Brent Tops $100 on Aramco Attack Claim as Insider Selling Sweeps AI and Cloud Stocks

On Friday, October 2, 2026, the clearest mover of the session was geopolitical, not macroeconomic. Yemen's Houthi movement claimed a missile and drone attack on a Saudi Aramco facility in Riyadh, and Brent crude, the global oil-price benchmark, traded above $100 a barrel. The mechanism was simple: an attack claim against the production base of the world's largest oil exporter raises the probability of an actual supply disruption, and traders bid the price up to cover that risk before any damage was confirmed, rather than waiting to find out. Two stories about artificial-intelligence infrastructure pointed in opposite directions. Applied Digital, which builds data centers used for AI computing, rose 5% after announcing a construction milestone, rewarding physical buildout tied to AI demand. CoreWeave, a cloud company that rents out AI chips to other firms, saw insiders — the executives and directors who run it — sell stock across the board in filings disclosed the same day, including $438 sales each from principal accounting officer Jeff Baker and executive vice president Chen Goldberg. The dollar amounts at CoreWeave were small, but the breadth of names selling at once was not. Four DocuSign executives, led by chief executive Allan Thygesen's $1.8 million sale, sold nearly $3 million in stock in rapid succession. Crowdstrike and Natera executives separately sold tens of millions between them, and Snowflake director Michael Speiser alone disposed of $17.45 million in shares. None of this selling forces a stock down by itself — insiders sell for tax and diversification reasons too — but when it clusters across this many high-multiple technology names in one week, markets tend to read it as a sign that the people closest to these companies see limited room left for further gains. The macro data cut against the usual logic that weak jobs numbers mean looser policy. A weak September jobs report was judged unlikely on its own to stop the Federal Reserve from tightening further, because inflation, not labor-market slack, has become the binding constraint on how much the Fed can ease. Treasury Secretary Scott Bessent reinforced that reading, dismissing the recent rise in Treasury yields — the interest rate the government pays to borrow, which rises when investors demand more compensation for risk — as part of a global trend rather than a warning specific to US policy. Ratings agency Scope added a longer-dated worry, forecasting that US federal debt would reach 160% of GDP, the broadest measure of national economic output, within a decade, a trajectory complicated by President Trump's continued public pressure on the Fed for lower rates. None of this was settled by the close. Bank of America called for the euro to weaken to $1.15 by year-end, betting that interest-rate divergence between the Fed and the European Central Bank keeps favoring the dollar. Berkshire Hathaway added to its homebuilder holdings even with the average mortgage rate near 7.5%, a bet on future rate relief rather than current affordability. That same tension between elevated-for-now and lower-eventually showed up in INDY's own Buy List 2026 model portfolio, which held a total return of +7.15% on €120,000 invested (price-only return +6.56%), with Bitcoin-linked names MicroStrategy (+69.03%) and GameStop (+34.48%) still the biggest winners even as insiders were selling heavily elsewhere in high-growth technology. Whether oil holds its new premium, whether the Fed actually tightens despite a weak jobs print, and whether the dollar moves toward BofA's $1.15 target are the questions the next session will start to answer.
