Top Funds' Activity in Q2 2026
Ken Griffin of Citadel in a letter to clients on Friday addressed for the first time the firm’s purchase of assets from Leopold Aschenbrenner’s Situational Awareness hedge fund.
According to a letter obtained by CNBC’s Sara Eisen, Griffin told clients that Citadel has unwound more than 80% of the aggregate risk from the original portfolio purchased by conducting more than 100 block trades over $4 billion in market value.
Griffin detailed in the letter that Citadel entered discussions with Situational Awareness to acquire some of the fund’s holdings on July 29. One day later, CNBC’s David Faber reported that Situational Awareness was forced to sell all of its public stock positions after facing steep losses. Citadel was later revealed as the buyer of the assets.
“A transaction of this magnitude could not have been completed without the extraordinary cooperation of the trading and prime brokerage teams at the banks serving both firms,” Griffin wrote in the Friday letter to clients. “I am grateful for the focused effort they brought to the rapid transfer of the portfolio.”
Griffin also confirmed the firm’s flagship multistrategy Wellington fund returned 5.94% in July, which CNBC previously reported marked the fund’s best monthly performance since 2022.
Situational Awareness as a hedge fund concentrated positions in the artificial intelligence trade, on a belief by 25-year-old Aschenbrenner that the technology would fundamentally reshape the world and the economy. At the same time, the fund had short positions in some software companies, a sector that investors have worried will be disrupted by AI.
However, the AI trade faltered in June and July — even while broader indexes appeared flat — with stocks that Situational Awareness had large stakes in, like Sandisk and Bloom Energy, tumbling more than 50%. At the same time, software names like Adobe rebounded, meaning the fund was losing money on both its long and short positions.
That set off both margin calls and compulsory sales at the fund.
Since Citadel stepped in to buy the fund’s publicly traded assets, the AI trade has rebounded, with Situational Awareness’ sale representing a bottom for the sell-off that started in June.
It's that time of the quarter again where we get a sneak peek into the portfolios of the world's most successful money managers, with a customary 45-day lag.
The data was out on Monday, but before I get to it, I led with this article on Citadel profiting off of Situational Awareness's woes, scooping up the portfolio on the cheap and then selling 80% as these stocks rebound.
All this happened in the last few weeks, an amazing story which I chronicled here, and it wasn't just Citadel that profited; other large hedge funds did as well in a coordinated attack where the ruling class of hedge fund kings taught young Leopold Aschenbrenner a lesson he will never forget.\
Citadel made a killing here. Its flagship multistrategy Wellington fund returned 5.94% in July, the fund’s best monthly performance since 2022. And keep in mind, they manage risk extremely tightly and handled the Situational Awareness portfolio perfectly, buying it at the right time and selling it when positions fully recovered.
How did it do this? Just look at shares of Sandisk, hit a low of $998 on July 29th and recently popped just shy of $1,827 on August 17th when Citadel probably sold a good chunk at a big profit (they bought at a discount so less than $998 a share).
And if you look at the major institutional holders of Sandisk here, you will see the regular large investors but dig a little deeper, and you'll see top hedge funds owned it as well (remember, this data is as of the end of last quarter).
Importantly, there was huge money to be made just trading this stock, and top hedge funds pounded on the opportunity (next quarterly filing will prove this).
What else happened this week? Former macro hedge fund manager turned Treasury Secretary Scott Bessent engaged in yield curve control, trying to bring down rates on the long end. So far his efforts have not worked, but he has a huge toolkit to work with.
I don't know, I agree with JPMorgan’s James Sullivan, the Treasury buybacks may offer temporary relief but risk merely shifting the debt problem down the road, and it's not bullish for the greenback.
Surging government and corporate debt supply, alongside waning foreign demand, could keep upward pressure on yields.
Of course, I have a solution for all this: slap on a 2% sales tax in the US and pay off some debt!!
Back to stocks. The Dow surges 500 points on Friday, but the index posted back-to-back weekly losses:
The S&P 500 rose on Friday as investors tried to find their footing following a steep sell-off driven by rising Treasury yields.
The broad market index climbed 0.43% to end at 7,674.37, while the Nasdaq Composite rose 0.43% to 26,180.45. The Dow Jones Industrial Average was up 517.80 points, or 0.98%, supported by gains in healthcare stocks such as Merck and Johnson & Johnson. The 30-stock index closed at 53,277.01.
The financials sector offered a boost to the broader market, with crypto-related stocks seeing sizable gains as bitcoin posted a weekly advance of 22%. Robinhood shares jumped almost 14%, while Coinbase added 8%. Materials also outperformed, up 2% on the day.
Wall Street is coming off a losing session, as Treasury yields resumed their march higher after the government’s efforts to stymie a sell-off in the Treasury market. Bonds, particularly on the long end of the curve, have been under pressure as investors fear rising inflation due to higher oil prices.
Thursday’s pullback ultimately led the S&P 500 to tumble 1.4% on the week, while the Nasdaq lost 2% in the period. Both indexes snapped three-week winning streaks. The Dow slid 0.9% for back-to-back weekly losses.
The downturn this week also affected stocks beyond the U.S., with the MSCI All Country World Index posting a weekly decline of almost 1%.
In the wake of the latest market drawdown, Leo Kelly, founder and CEO of Verdence Capital Advisors, thinks equities could see even more losses — particularly, a slide toward correction territory in the fall — if Treasury yields continue to rise and tensions in the Middle East persist.
On Friday, longer-dated yields continued their ascent, with the 10-year Treasury note yield gaining more than 3 basis points to 4.734%. The 30-year Treasury bond yield advanced more than 3 basis points as well to 5.273%.
“The market has adjusted to 4% to 5%” on the 10-year yield, Kelly said. “If we had some sort of event and the market broke out and went to the 6% to 7% range on the 10-year, that’s a problem, and the market will react poorly to that.”
With yields higher, investors will be turning to next week’s speech from Federal Reserve Chairman Kevin Warsh at the Jackson Hole Economic Policy Symposium for more clarity on that front, as well as other areas such as central bank independence.
For the week, here are the top-performing US large-cap and mid-cap stocks (see full list here and here):
I circled some of the symbols I tracked closely this week. For example:
- Moderna shares (MRNA) surged 129% this week on promising results of its cancer vaccine for melanoma. Among its top holders Fidelity, BackRock, Vanguard, Baillie Gifford and Two Sigma.
- Shares of Amylyx Pharmaceuticals (AMLX) surged 79% this week after after its treatment candidate for post-bariatric hypoglycemia (PBH) reported strong results in phase 3 clinical studies. Among its top holders, you have Fidelity, BlackRock, Perceptive Advisors and Vanguard.
I'm just showing you two examples here but you really need to do a lot of work to understand who bought which stocks and who did well and why.
Importantly, things move in real time, not lagged time, but you can still learn a lot by paying attention to where top funds are focusing their attention and add that information to your toolkit.
What else? If you look at the top performing stocks year-to-date (full list here), you'll see a lot of stocks up 300% or more, which shows you trends tend to persist in this market:
I circled a few, including 10x Genomics (TXG), which Stanley Druckenmiller's Duquesne family office owns (and made a killing off of, see his positions here).
Again, I don't expect people to look at all the top funds' holdings below and if you don't understand how to technically analyze daily or weekly charts or if you don't understand biotech stocks, forget about it.
I'm providing you a toolkit, your analysts need to dig hard here to figure out opportunities and then discuss with portfolio managers who need to trade these stocks and figure out the right setup.
Is there alpha here? You bet there is but you need to know how to find it and take the appropriate risks.
Ok, let me wrap this up, time to enjoy my weekend.

returns, typically using high-frequency models so they churn their
portfolios often. A few of them have outstanding long-term track records
and many believe quants are taking over the world.

science to develop their algorithms. Market neutral funds will

Top Deep Value, Activist, Growth at a Reasonable Price, Event Driven and Distressed Debt Funds
These are among the top long-only funds that everyone tracks. They
include funds run by legendary investors like Warren Buffet, Seth
Klarman, Ron Baron and Ken Fisher. Activist investors like to make
investments in companies where management lacks the proper incentives to
maximize shareholder value. They differ from traditional L/S hedge
funds by having a more concentrated portfolio. Distressed debt funds
typically invest in debt of a company but sometimes take equity
positions.
