The S&P 500 index has been crushing private-equity returns in the past year, and Blackstone ’s second-quarter results illustrate that trend.
As part of its earnings release early Thursday Blackstone said its corporate private-equity returns in the year ending in June were 11.3%. That compares with a 24.5% total return for the S&P 500.
In the prior year ending in June 2023, the S&P 500 topped Blackstone with a 19.4% return against 9.7% for the firm’s corporate private-equity business, which has $145 billion of assets and remains one of its most important areas along with real estate.
Blackstone is the leading alternatives firm with over $1 trillion in assets under management and has the largest market value of any public investment firm at more than $160 billion.
Driven by Nvidia , Microsoft , Apple , Amazon and other big technology stocks, the S&P 500 has handily topped most asset classes in the past several years.
Another sign of more difficult times for private equity came earlier this week from Calpers, the $503 billion California pension fund, when it reported it s preliminary returns for its fiscal year ending in June . Calpers is one of the first major endowments or pension funds to report results for the June fiscal year. undefined The pension fund, a major player in private equity, said its private-equity investments gained 10.9% net of fees—although that figure is lagged one quarter. Calpers’ public-equity investments were up 17.5% in the year ended June—its strongest asset class. Private equity remains a favorite of many pension funds and leading university endowments like those of Harvard and Yale. Their view is that private equity can beat public-market returns over the long term.
But the private-equity business has gotten tougher in recent years due to keen competition for deals, higher interest rates and a less receptive IPO market, which has made exits tougher.
And private-equity portfolios of firms like Blackstone look nothing like the S&P 500, given their investments in small to midsize companies.
Blackstone, for instance, bought a majority stake in Emerson’s climate technologies business last year and more recently purchased Tropical Smoothie, a franchiser of fast-casual cafes. It also holds a stake in Bumble, the publicly traded online dating site, and it’s an investor in actress Reese Witherspoon’s media company, Hello Sunshine. Blackstone’s corporate private-equity business runs $145 billion and has 82 investments, according to the firm’s website.
Blackstone’s private-equity business has strong long-term returns including a gain of over 50% in the year ended in June 2021 when it handily topped the S&P 500 index.
But the S&P 500 index has become difficult to beat more recently and it’s dominated by some of the best companies in the world. It carries less risk than private equity, given the cash-rich balance sheets of its leading companies like Apple , Microsoft and Alphabet .
Private-equity firms, by contrast, often use considerable leverage to boost returns. Investors can get exposure to the S&P 500 through index funds that charge 0.1% or less in annual fees and with immediate liquidity.
A key risk with the S&P 500 is its vulnerability to a selloff in the leading tech firms that now make up over 40% of the index. The recent rotation into smaller companies illustrates that.
Blackstone shares gained 1.1% to $136.31 Thursday in the wake of its earnings news as investors focused on rising investment deployments and positive management comments on the firm’s outlook.
The firm’s nearly $40 billion of inflows and $34 billion of capital deployment during the second quarter marked “the highest level of investment activity in two years,” Chief Executive Officer Stephen Schwarzman said in a statement.
Citi analyst Christopher Allen wrote in a note to clients on Thursday that while Blackstone’s overall performance was mixed, the outlook appears to be improving given fund-raising and deployment trends.
Investors also were heartened by Blackstone President Jon Gray’s comments about a bottoming in commercial real estate and strong capital deployment in that area.
But ultimately, the game for Blackstone and its alternatives peers is about performance—particularly beating low-fee public investments like the S&P 500. That seems to be getting more difficult.

Wall Street’s hottest momentum trade has reversed sharply, as former winners tumble and heavily shorted stocks surge.
Wall Street’s hottest trade has gone ice cold.
For years, it paid off to buy stocks that were rising in price—and bet against struggling shares. The momentum trade was especially profitable this year, as investors piled into hot stocks including Micron Technology, Nvidia, Advanced Micro Devices and other artificial-intelligence darlings while wagering against those likely to be hurt by the embrace of AI.
The S&P 500 Momentum Index soared 44% in the second quarter, its best quarterly performance on record, and it surged 133% over the past five years, nearly double the broad market’s performance.
Mega funds and rookie investors alike piled into the trade, some using leverage and options contracts in an effort to amplify their returns, propelling the underlying shares higher.
“It is a self-fulfilling prophecy,” said Matthew Tym, managing director at Cantor Fitzgerald, of the trade.
Suddenly, the trade is a loser. The momentum index has tumbled more than 9% since July 1, lagging behind the S&P 500’s 2.8% gain. The index—which tracks stocks in the S&P 500 based on a “momentum score”—is on track for the biggest quarterly underperformance in 25 years. July was the second-worst month for the momentum trade in around 40 years, according to Bank of America estimates; the only month worse was April 2009, in the teeth of the global financial crisis.
Hedge funds that bought momentum shares while shorting low-momentum stocks suffered even more. At the same time, a basket of the most popular stocks held by hedge funds tracked by Goldman Sachs recorded its biggest one-month underperformance in July relative to the S&P 500 in more than 20 years, according to the bank’s analysts.
Momentum trading is based on a rather simple observation: Investments that go up tend to keep outperforming; those that underperform often remain laggards. This kind of trading might seem too simple a stock-picking strategy to work. Yet it often has.
“For decades, it didn’t take a lot of sophistication to run a momentum strategy and make a decent living at it,” says Agustin Lebron, senior researcher at EquiLibre, a trading firm.
Part of the reason: It takes a while for corporate and other information to spread to various investors, so they slowly build positions, producing buying momentum.
“A huge pension fund can’t flip around its positions in a day,” says Lebron. “Behavioral biases also account for some of the effect, as well—people tend to sell their winners too early and hold losers too long.”
Fans of the strategy point to the human tendency to extrapolate from past results—and chase investment returns—noting that momentum patterns have been evident in markets for decades, even centuries. They also say that some of the worst months for momentum strategies are during longer periods of outperformance.
Some have been doing the trade by buying the strongest investments in a sector while shorting the weakest; others lean in to rising markets or asset classes. Still others use a quantitative approach or turn to banks or others who sell ways to make distinct wagers on momentum as a “tradable factor” or a “thematic basket.”
The fans remain believers. “Any strategy has disappointing periods,” says Antti Ilmanen, global co-head of the portfolio solutions group at AQR Capital Management.
The surge in Moderna and other biotech stocks helped crush the momentum trade. These shares were among the most heavily shorted in recent years, but positive news on a cancer vaccine from Moderna and Merck sent those stocks flying, crushing some quant and other hedge funds. Moderna is up around 150% so far this month.
These traders had an especially rough day on Aug. 19, which Goldman Sachs told its clients was the worst day for “systematic long-short managers” in more than two years. About half of the losses were because of momentum trades, the bank said.
Some traders have begun to short, or bet against, the very stocks that propelled the momentum trade earlier this year. Net short positions in futures tied to the Nasdaq-100 index among speculators recently climbed to some of the highest levels of the past two decades, according to data from the Commodity Futures Trading Commission.
The about-face is a sign of how markets have become more treacherous for investors, even as indexes keep climbing. Part of the issue: the recent meltdown of Situational Awareness, a hedge fund that had piled into some of the most popular momentum shares, including chip stocks. After a period of market tumult, Nvidia shares rocketed almost 9% after its earnings, showing how quickly sentiment can shift.
Some investors say the run-up in share prices driving tech stocks higher reminds them at times of the dot-com frenzy decades ago.
Mike Ogborne, the founder of San Francisco-based Ogborne Capital Management, said he has grown more cautious on technology stocks and is keeping more of his portfolio in cash than he typically does.
And he is nervous about the surge in spending by technology giants and quarterly capital expenditures that keep rising.
“It is a little bit like Cinderella and the clock striking midnight. You don’t know when midnight is going to come around,” Ogborne said. “They don’t send a memo around telling you when the capex cycle is over.”
