The S&P 500 climbed 1.05% last week, while the Nasdaq Composite ended the week up 1.59%. Those numbers, while unostentatiously positive, do not tell the story of last week’s drama. This was a week with earnings from key tech players, a meeting of the Federal Open Market Committee (FOMC), and big news from a buzzy new hedge fund. The result was wild swings in both indices.
We saw outsized reactions from the market after some of the anticipated big tech earnings reports this week. On the winning side, Microsoft set a notable record on Thursday, notching the largest single-day market-cap increase ever seen – $450 billion. This strong showing came after MSFT 5.17% announced healthy Azure cloud growth and, unlike some of its Mag Seven brethren, committed to continued positive cash flow. Meanwhile, Meta META 6.51% was down as much as 11% at one point in Wednesday after-hours trading after its earnings report triggered nervousness regarding its capex spending and its steep decline in cash flow. Meta’s earnings miss, while in part due to significant one-time charges, likely didn’t help ease that nervousness, and the shares sank another 9.7% on Thursday.
The FOMC held its July meeting on Wednesday, and while our Chart of the Week (below) shows that markets had a negative reaction to what they saw and heard, Fundstrat Head of Research Tom Lee’s take was contrarian bullish. As he noted, the anticipated number of Fed hikes before the end of the year (as implied by Fed Funds futures trading) fell after the meeting, from 1.83 hikes to 1.32 hikes.
Nevertheless, the post-meeting surge in long-term yields triggered a sharp decline in the stock market, likely contributing significantly to the third major market event this week – a sharp reversal in fortunes for Situational Awareness, a buzzy hedge fund founded in 2024 by former OpenAI Superalignment researcher Leopold Aschenbrenner. The post-FOMC decline in stocks, including AI stocks, appears to have hit the fund’s aggressively leveraged bet on AI stocks (along with short bets on areas like software) hard, triggering margin calls that forced the liquidation of nearly all of its positions in publicly traded companies. To Lee, margin calls throughout the market, including those that hit Situational Awareness, “in some ways explain why the AI trade really fell off the cliff over the past few days.” Consequently, he suggested, “I think this is establishing a structural bottom.”
Head of Technical Strategy Mark Newton is less certain. “I’m not sure that this week marked any sort of meaningful low, even if one hedge fund had to liquidate some holdings,” he told us at our weekly research huddle. “There is some gravity that is taking down parts of tech that got stretched, and it’s important to pay close attention to that,” in his view.
On the other hand, Newton pointed out that “we’ve seen many parts of technology, even some that we thought were really starting to stabilize, have now fallen out of bed even further, and meanwhile, equal-weighted S&P made new all-time highs on Tuesday. […] You have a lot of areas in the market that are really, really working well, areas like health care and financials,” flagging them as what he views as “the top areas to be in right now.”
Still, Newton left us with this cautionary reminder for those inclined to panic: “Although equal-weighted S&P RSP 0.62% has done very well since the spring, it now is up to pretty strong technical resistance. That’s something to remember for anyone thinking about dumping tech: As the old saying goes, don’t throw the baby out with the bathwater.”

Chart of the Week

The FOMC held its July meeting on Wednesday. While the central bank opted to keep rates steady at 3.5%–3.75% for the fifth straight meeting, three voting members dissented, voting for a 25 bp hike. As seen in our Chart of the Week, the S&P 500 reacted ultimately saw a notable drawdown of 1.31% from the end of the meeting until markets closed that day, which helped trigger margin calls for aggressive investors such as the hedge fund Situational Awareness.
