Investing Billions - E314: How Endowments Actually Think About Risk

Episode Date: February 27, 2026

If private equity generates alpha, why are investors still paying for beta? In this episode, I sit down with Roger Vincent, Founder and CIO of Summation Capital, to break down portfolio construction, co-investing, and fee alignment in private equity. After more than a decade leading Cornell University’s multi-billion-dollar private equity portfolio, Roger shares why diversification in PE actually increases expected return, how elite endowments use co-investments to systematically reduce fee drag, and why most allocators are misaligned with the capital they steward. We also unpack Summation’s industry-first structure—charging carry only on alpha over a public benchmark and offsetting fees through a no-fee, no-carry co-investment program.

You spent many years at the Cornell Endowment managing $2.5 billion at the time and generating some pretty spectacular results. What did that teach you about investing? I was at the Cornell Endowment for about 12 years. I left in 2024, so I got to invest there throughout an extended cycle through a cycle. What I really learned about that experience was how important portfolio construction is to investment returns. And I think it's an area that people have under invested in, underspent time thinking about, and there's just a lot of value that investors can get by focusing on how they construct the portfolio that their asset classes are made of. Why is portfolio construction such an underrated thing?

Just taking the one asset class that I really spent my time on, which is private equity, which we think of as everything from early state venture capital to growth equity to buyouts around the world, there's an incredible diversity of ways to generate the types of returns that are attracted to us as investors. And how you put those together in a way where the whole is more than the sum of the parts is really critical. What are some examples of some assets that play a very specific role that complement the rest of private equity portfolios? Venture capital is a great example, over long time horizons, venture capital has produced the best returns, and that's at the median level. It also has produced the best opportunity for outperformance by selecting first core tile

managers, but it does this with a lot of cyclicality. And so if you make an entire portfolio out of nothing but venture capital, it may have characteristics in terms of highs and lows and and lack of cash distributions that aren't tolerable for most asset owners. The most common misnomer is that you either have to sacrifice returns to get diversification that protects you from uncertainty to come. And so I tend to find that most investors feel like there's a tradeoff there. If they want to generate high returns, they need to be highly concentrated and take all the risk associated with that.

and if they want to de-risk and be more broadly exposed, that comes at the expense of higher returns. Last time we chatted, we have this interesting conversation about the public markets, and exposure to beta has more or less become a zero-cost basis with index funds and ETS. But that hasn't happened in the private markets. Why is that? Why didn't the private equity industry keep up with the times? It's hard to say. There are a lot of examples in financial markets.

of fee structures being a lot stickier than people think they should be. I would guess that in private equity, one of the reasons is it's been somewhat insulated from competitive pressures because of this large secular growth that we've seen in the asset class. And so as it's gone from this very niche part of the market to this very significant part of complex large institutional portfolios, that growth has led to demand for products that probably has enabled people to survive with stale fee structures. There's this constant product innovation. People are willing to pay for new products.

Professor Steve Kaplan has done numerous studies on this, that private equity, buyout and venture capital has alpha, roughly three to 500 basis points, net of fees. So the whole argument from the GP side is, yes, you're paying a lot, but you're actually on a net basis. You're still getting your 300 to 500 basis points a year. One of the hardest things of investing is seeing what should, before everyone else does. For decades, only the largest hedge funds could afford extensive channel

research programs to spot inflection points before earnings and to stay ahead of consensus. Meanwhile, smaller funds have been forced to cobble together ad hoc channel intelligence or rely on stale reports from sell-side shops. But channel checks are no longer a luxury. They're becoming table stakes for the industry. The challenges has always been scale, speed, and consistency. That's where AlphaSense comes in. AlphaSense is redefining channel research. set of static point in time reports, Alpha Sense channel checks delivers a continuously refreshed view of demand, pricing, and competitive dynamics powered by interviews with real operators, suppliers, distributors, and channel partners across the value chain.

Thousands of consistent channel conversations every month deliver clean, comparable signals, helping investors spot inflection points weeks before they show up in earnings or consensus estimates. The best part, these proprietary channel checks integrate directly into Alpha Sense's research platform trusted by 75% of the world stop hedge funds with access to over 500 million premium sources, from company filings and brokerage research to news, trade journals, and more than 240,000 expert call transcripts. That context turns raw signal into conviction. The first to see wins, the rest follow. Check it out for yourself at alpha dash sense.com slash how I invest. You know, Professor Kaplan's work has been incredibly influential in the endowment

world that was influential on how I thought about investing at Cornell, how he measures outperformance has really become the industry standard and has been a great new tool that we've had at our disposal. And so, yes, the industry does on average generate alpha. That doesn't mean that people should be paying for the part of the returns that is not the alpha, and that's the beta. Ed. One of the interesting things about the allocator world is the incentives for allocators. Tell me about what those incentives are and maybe how they sometimes diverge with the underlying pool of capital. Incentives are incredibly important. I often say if there's only one word that one needs to describe my style of investor or what I think is the most important word in investing, it's alignment. And so how you set up incentives either creates that alignment or creates that. misalignment. And I'm just going to be a little bit more specific. Anybody who invest in private equity, who's not a GP, is allocating. And so that allocator might be an endowment. That allocator might be

a fund of funds. That allocator might be a high net worth individual that's picking funds themselves or picking direct investments themselves. They're allocating on their own behalf. They're both the asset owner and the allocator. So endowments are really interesting because they've been allocating to private equity probably as a group longer than just about any other group of asset owners. And they've been doing at a greater scale, I would say they've achieved greater sophistication than anybody else. And one of the things that the endowment allocators have done, which is really unique and impactful, is they've set up better alignment with their allocation teams. In my experience, certainly at Cornell, but also knowing how many of my peers operate,

the way they incentivize the team is relative to benchmark performance. And so their view is that everybody should be accountable to a benchmark of what one would expect to achieve in their asset class. You know, typically this is an investable, passive way of accessing something quite similar. And that the only real value that that allocation team is bringing is outperformance over that benchmark. Do you think that's the right way to approach it? Shouldn't it make sense to benchmark private equity against other private equity funds? Why benchmark against public indices? Well, the deeper answer is we're going to evaluate performance of a private equity portfolio

about 25 different ways. And we're going to use each one of those evaluations for a different purpose. So, yes, we are evaluating the performance of the private equity portfolio against other private portfolios. were assessing each individual fund against other individual funds of their same style in vintage year and a quartiling exercise. But for compensation, the philosophy is that you want to pick something that represents your cost to capital. And most endowments are really just very sophisticated 60-40 portfolios, where about 60% of the allocation is to equity exposure. And if,

the team weren't there and they wanted to run essentially the same portfolio, they would just put that in that 60 points in liquid passive beta. And so the active choice that is being made by the asset owner, the institution is to go hire a bunch of allocators, have then take what was a passive and liquid asset, make it active and illiquid. and in that hope to generate excess performance. How do endowments like Cornell and other IVs leverage co-investments to their advantage? You see a number of institutions, but certainly not all, applying some level of co-investment to their portfolios. And this could be direct investments or co-investments alongside an existing manager. Where I will tell you, the industry really is that the most sophisticated investors are doing some level of co-investing with their existing managers to average down that fee load. And so rather than the

industry coming off the two and 20 fee structure and saying maybe today it should be one and a half and 15, it's really for the most part sticking to two and 20, but allowing its larger, more sophisticated investors to achieve an all-in lower feed burden if they take the time and the effort to go and co-invest. So there's a lot of people out there that are paying, you know, rack rate and then a number of more sophisticated players out there that are using this tool to, to average those fees down. And so it's, it's a really great tool to have. Some people are probably taking it a little too far. And, you know, the question I would ask them is, are you really, you know, the best investor in the world, all of these different little pockets of the market such that you can go and eliminate that fee by doing it yourself.

Or are you going to be better off working with the world's best investor in that area and paying them the fees? And we were able to generate significant outperformance at Cornell, predominantly just working with the people that we thought were the best investors in that market. I've spoken with hundreds of family offices that tried to do direct, maybe a couple hundred. A couple edge cases have worked. Almost all have failed. In other words, what's worse than two and 20 is paying 100% of your investment into mistakes. The couple that have worked have very much stuck to their knitting. They had a manufacturing company. They would do direct investing into manufacturing plants. They had an oil rig. They would direct invest into oil rigs. In a case where they could not only assess, but they had the right to win against other private equity funds and other pools of capital. in that very much category. That's the only case that I've seen that has worked over time. That completely makes sense to me. I could see that people, if they really had an area of expertise, could invest there successfully. The problem is that, you know, most people don't have expertise in everything. And so, you know, if that's your only strategy of investing,

you're going to have very poor diversification. And so I think of there as being a spectrum that people can be on depending on what kind of return they're trying to achieve. If you are an endowment, let's just say you're in the, you're rich category, we want to stay rich category. And so the strategy that the endowments are following is designed to get the highest expected return with the lowest variance of potential outcomes. And so the diversification, the portfolio construction that we engage in is intended to do this, to increase the expected returns, but to constrain both tails, but particularly the left tail. At the full other extreme, if you want to make money, you know, the best way to do this is to be concentrated. And it's no surprise that the richest

people in the world are the entrepreneurs who make all of their money by investing in a single company. Have you been waiting for the perfect time to upgrade your tech? Good news. The wait is over.

They've made their money that way. And now there's somewhere along this spectrum where they maybe have some tolerance for concentrated risk to keep growing that wealth. But they probably have some portion of their wealth that they want to make sure is being managed in the more endowment style where they're getting the best return possible, but really keeping a very careful eye on risks that can be diversified away. And co-investment is an art in of itself. I'd argue it's a little bit easier in buyout than venture capital. How does one become an elite co-investor when it comes to investing into venture capital co-invest? That's a really interesting question. The perspective I bring on it is before I was at Cornell, I was a GP. And so I've actually spent the majority of my career still at this point, having served as a GP, doing,

deals, syndicating co-invest. And so I understand quite a few of the things that GPs are thinking about when they are syndicating something. And there's a lot of value that the co-investor can bring to the table other than the capital. And one of them is certainty and clarity and predictability. And so when we co-invest, we have a process that we think is rigorous, but very easy for the GP to work with. And so a problem a lot of family offices have is they're under-resourced and maybe they're new to this and they're not as easy to be capital partners with from the perspective of the GP. Your question on venture capital is a difficult problem for anybody to solve. The thing about venture capital is there's just a very big difference between early-stage venture

capital and late-stage venture capital, just to pick two extremes. And, And most of the co-investing that one will see in venture capital is going to be at the late stage. That's when big dollars are being raised. And so nobody's going out and syndicating a seed or a pre-seed investment opportunity because the check is already very small. And so one of the problems which people have, if they want to co-invest in venture capital, is that they have to think about what stage they're going to get exposure to relative to what stage they're trying to get exposure to. And so there's that challenge. The other challenge is the power law.

I think at this point, everybody really understands that there's a very long right tail to venture capital returns. And if you don't happen to have exposure to a piece of that right tail, the expected return in venture capital can be very low. And so, again, this comes down to portfolio construction. You have to make sure that you are making enough co-investments. and you're getting enough venture capital exposure that something is very likely to be in that right tail. You're going to have a big winner in there. So being able to do this at a very high volume

is critical to getting the returns that you're hoping to get. In that vein, you might have two investments. One, your foot is an ice, ice hot water, 10X. The other one is ice cold. It's a zero. On average, you should feel like it's a 5x, but it feels either very cold or very hot. Are there structural ways that institutional investors get around the variance of co-investments?

And what are some best practices for that? You're bringing up a great broader topic, which is behavioral finance. And I think that the institutional approach that I learned at Cornell really tries to take some of the emotion out of private equity. And so one approach that most endowments are following, certainly, you know, I follow is to be more systematic about your co-investing. And we're trying to build a larger portfolio of co-investments. We're really trying to capture that 600 basis points of fee saving without introducing additional risk into the portfolio. And so if you only do this once, you're introducing a lot of risk.

the situation is fairly binary. You're probably going to lose all your money, your cold foot. Maybe you're going to make a lot of your money, but you've just turned the whole situation into a bit of a coin flip. What we want to do is make sure that we're doing enough of these. We don't have to get that out of shape if one of them doesn't work. If they're enough there, and we're doing them in a way that is rigorous with some of the best investors in the world, we'll get our fair share of winners. And at the extent, end of the day, day, what do we expect to achieve? We expect to achieve similar returns to what we would have gotten with the funds, but 600 basis points higher because of the fee savings. And if you go and look at

the academic research on co-investing in private equity, what you will find is the rigorous analyses show that it outperforms by almost precisely that amount, the fee savings. You've now taken all the insights that you had from Cornell earlier in your career as a GP and started summation capital a couple of years ago. What does summation capital do? Summation really tries to take private equity and make it accessible to people who don't want to do it themselves. And what does that mean? It means having somebody who is professional at operating this style of a portfolio, professional at underwriting management, you're writing managers, professional at constructing that portfolio in the right way. These are very

deep skills and the relationships that you have to have in the industry or deep relationships. Most people don't have them and they take a very long time to generate. So I didn't think that everybody who wanted to have good exposure to private equity needed to reinvent the wheel on this. So what we're doing is making that endowment style of, private equity available to a much broader set of asset owners. We do this by generally following the investment strategy that I implemented at Cornell and is very similar to what you would find at any large, sophisticated endowment. But then we innovated in a couple of ways that the market hasn't seen before.

And we innovated to get the alignment right. We innovated to get rid of fees that were really detractive to return. and we innovated to make the product simple to use. And when people can't do that, what I find too often is they go for second choices. They go for very poorly constructed portfolios like you alluded to before. And you construct endowment style portfolios. What does that mean? What's the practical difference between that versus a typical family office portfolio?

I don't think most people appreciate how much diversification is in a large, well-constructed portfolio. So the data shows that your average large endowment, I'm talking about endowments with more than $5 billion, something like 50 to 75 GPs in it. Take that number, multiply it by three or four to get to the number of funds that you might be managing because these are typically long-term relationships where you're going to be in multiple funds over time with each of these managers.

And then each of those funds has underlying, multiple underlying portfolio companies. So now you're going to get to many dozens of managers, you know, hundreds of funds and thousands of portfolio companies. Very few families and other asset owners that I've ever come across are able to achieve or even understand the benefits of achieving that level of diversification. And if they did understand it, their ability to go and implement it would be pretty constrained. Some would call that dewarcification, meaning you're just getting,

getting to beta, why is that not over diversification? I love that you ask this question because I get it a lot. I think this really goes to the crux of the misunderstanding. And we think that that level of diversification doesn't drive returns towards the media and actually increases your expected return. And one of the analogies I give to use, you know, used to give this is I'll comment a couple of different ways. When I was coming up in the investment world and when I was learning about investing, even before I was actively investing, there were really two philosophies on how to invest.

One, I credit to John Bogle, who said, look, don't try and beat the market, just try and keep your fees low, take the index. And so that's, you know, that's full diversification in the context of liquid equities. And the other, I really credit to Warren Buffett. And he said, look, put all your eggs in one basket and watch it like a hawk. And you had to somewhat choose between one of these two philosophies. And the view, I think as you're expressing it is a little bit like if you're not taking the Warren Buffett approach, then you're automatically just going towards the beta of the market. Now, first, let me say that the beta of private equity is not a bad return. As Steve Kaplan showed, there's pretty reliable performance there over liquid equity markets and over long periods of time,

hundreds of basis points can really add up into a meaningful difference of outcomes. What I discovered at Cornell was, and really worked on was a third philosophy. And this is what I call to gather a bunch of hawks who are each watching their own nest like a mother hawk, you know, like a hawk and watch them like a mother hawk. And so that's really what we're trying to do. We don't disagree that being specialized and being focused and even being concentrated is a benefit. we think it's a benefit at the GP level. And that's the power of what the endowments are doing, is they're getting the benefit of that specialist

and that expert in that segment of the market, and they're getting the benefit of the broad diversification by spending the time to do the work to build these types of complicated portfolios. It seems like the sin that a lot of institutional investors make is they double diversify. What you don't want is you don't want spikiness on a portfolio construction level,

But people equate those two things and they end up making sure that every single manager kind of hits this 2 to 2.5 expand. And the way to accomplish that is to never take any guess, to just be beta and everything. That's absolutely right. And essentially, if you're paying your allocator to do diversification for you, and then you're also paying a GP to run a massively diversified portfolio, you just pay two different people twice for the same thing. Yeah, Silicon Valley has roughly a 50% success rate in terms of figuring out the next great wave.

But if you had invested in every single trend, you'd have done extremely well, but you would have been wrong 50% of time. It's sort of a paradox. For summation capital, you've aligned incentives in a unique way. Tell me about that. And how do you measure your own performance? It's unique in the financial world, in the financial markets. It's completely standard in the endowment. world. So as I already said, I like pretty much everybody, if not everybody in the endowment world,

was primarily compensated based on performance, but relative outperformance against a reasonable benchmark. And so for most of the time I was at Cornell, I had to outperform liquid equities to justify that I created value and to be able to make a case for receiving performance compensation. This became my standard way of thinking that this was the right way to compensate people. Why else are we locking up our liquidity, arguably taking greater risk in private markets, other than to outperform what we could get quite easily for free in liquid equity markets? I went looking for that fee structure in an investable product. This was a number of years ago.

and I was shocked to realize that, to my knowledge, this was back then, but it's also today, there's not a private equity fund, there's not a private equity fund of funds, there's not a private equity advisory firm, there's not a private equity bank, focused bank that will enable you to get private equity exposure. This is anywhere in the world in history of the asset class where you can put even a portion, if not primarily pay them on the performance of Alpha. Well, Roger, love what you're doing.
