This was a week that started with earnings and ended with a geopolitical oil shock, and the two stories barely touched. Tesla lost roughly $140 billion in market value in one session, Brent crude broke $100 for the first time since May and gave most of it back within 24 hours, and the S&P 500 finished basically flat while the Nasdaq bled out under chip-stock pressure. Here's what actually moved money this week, July 20 through 24.
How did Tesla's earnings hit the stock?
Tesla beat revenue estimates but missed badly on profit in its Q2 2026 report. Revenue hit a record $28.2 billion, up 26% year over year, while non-GAAP earnings per share came in at $0.33, well short of the roughly $0.53 analysts expected. The stock fell about 14.5% on July 23, its worst single session in years.
Operating income fell 57% to $398 million as operating margin compressed to just 1.4%, down from over 4% a year earlier. That's the number that mattered, not the revenue beat. Deliveries and top-line growth held up. Regulatory-credit income and pricing did not. The stock opened near $374 and closed near $320, wiping out an estimated $140 billion in market cap in a single session.
Why did oil spike past $100 and then fade?
A Houthi attack on two Saudi oil tankers pushed Brent crude above $100 a barrel Thursday for the first time since May, widening the risk premium already built into prices from disruption near the Strait of Hormuz. The spike proved short-lived: Brent gave back most of the move by Friday on reports of a possible revival in US-Iran talks.
Houthi forces struck the tankers Encelia and Layla with drones and missiles in the Red Sea on July 23, setting one vessel on fire with the crew reported safe. Brent jumped as much as 6.3% to touch $100, its first close above that level since late May. By Friday, Brent had dropped roughly 4% to settle near $97, its sharpest one-day drop since late June, after reports that Pakistan, backed by China, was working to revive stalled US-Iran talks. WTI slipped toward $89 but still finished the week up around 10%. The pattern is becoming familiar this summer: a shipping attack sends a risk premium into the price fast, and it fades just as fast the moment there's a diplomatic off-ramp.
What happened to the dollar and yields this week?
The dollar kept climbing against the yen and Treasury yields held near multi-month highs, both consistent with a market that has largely stopped pricing near-term Fed rate cuts. Neither move was new this week so much as a continuation of a trend that has been building since the ECB's policy decision on Wednesday.
The ECB held its rate at 2.25%, and USD/JPY pushed to its highest level in roughly 40 years as the rate gap between the US and Japan stayed wide. The 10-year Treasury yield sits near its highest level since January.
How did the major indexes close the week?
Stocks closed a second straight losing week. The S&P 500 finished essentially flat on Friday while the Nasdaq Composite fell for the week on renewed AI-capex spending worries that hit chip and hardware names hardest. Breadth was weaker than the headline index moves suggested.
The S&P 500 closed July 24 at 7,412, up just 0.05% on the day, while the Nasdaq Composite slipped 0.64% to 24,976, down about 2% on the week. The VIX closed at 18.58, down slightly on the day but still elevated versus its summer range. Semiconductor and hardware names took the brunt of the selling, with names like SanDisk down double digits on the week.
What did insider and congressional filings show?
3M's group president and chief legal officer both sold stock this week following same-day option exercises, a routine pairing rather than a bearish signal. Alcoa's and Bank7's top executives also sold shares. A United Therapeutics executive sale making headlines is actually part of a scheduled 10b5-1 plan, a lower-signal event than a discretionary sale.
Kevin Rhodes, 3M's EVP and Chief Legal Officer, sold 7,669 shares at $171.20 for $1.31 million on July 22, leaving him with 43,779 shares. Group President Christian Goralski sold 4,902 shares at $170.46 for $835,577, leaving him with 6,971 shares. Alcoa's Chief Operations Officer Matthew Reed sold 4,600 shares at $46.82 for $215,372, tied to vested restricted stock, leaving him with 71,770 shares. Bank7 Corp CEO Thomas Travis sold 6,500 shares for roughly $312,000, about 2.6% of his stake, continuing a pattern of sales over the past year with no offsetting buys.
United Therapeutics CEO Martine Rothblatt also sold shares this week, but these sales are part of a pre-arranged Rule 10b5-1 plan adopted in November 2025, with recurring roughly 9,500-share tranches executed near $540 to $553 a share through the summer. Scheduled 10b5-1 sales are set months in advance and don't reflect a same-week view on the stock.
One filing that isn't really an insider signal at all: B&R Technology Merger Corp's sponsor bought $6.875 million of private placement units alongside the SPAC's $325 million IPO, which priced July 21. That's standard sponsor funding built into the deal structure, not a discretionary bet on the merger.
On the congressional side, Rep. Debbie Dingell disclosed a Freddie Mac mortgage-backed security purchase filed with the House on July 20, continuing a pattern of agency-debt buying she has made through the year.
What is WallStreetBets watching?
Retail sentiment skewed bearish on SPY this week and bullish on Micron, a split that says more about what traders are debating than where either is headed. Tesla, SpaceX, and QQQ all drew mixed, divided chatter rather than a clean consensus in either direction.
The negative SPY chatter tied to Middle East tensions and the yield move, per the terminal's social sentiment feed, while Micron traders framed memory-chip tightness as a profit driver even as the broader semiconductor group sold off. Retail positioning like this is a sentiment gauge, not a signal to trade against or with. It tells you where attention is concentrated, not where price is going next.
Next week brings the heaviest stretch of the summer. The Fed's rate decision lands Wednesday at 2:00 PM ET, with Microsoft and Meta reporting earnings the same afternoon, and Apple and Amazon following the next day. Four mega-cap earnings prints stacked against one Fed decision inside 48 hours is a setup that will likely move dealer gamma exposure more than any single headline did this week.
