Weekly Roundup: Tesla -14%, SMCI +24%, and the Mall Apocalypse Is Real

Welcome to the week where the market decided to have a full identity crisis. The S&P 500 finished basically flat for a second straight week (first back-to-back weekly loss since March), but that headline number is doing a lot of heavy lifting. Dig one layer down and it's carnage: $TSLA dropped 14% in a single session, its worst day in over a year, after earnings showed margin compression and a capex story that spooked investors who already spent two days watching $GOOG fall 7% on the same AI spending anxiety. The Mag 7 posted their worst single-day drawdown in five years. Cool, totally fine, nothing to see here.

Meanwhile, on the opposite end of the universe, $SMCI (Super Micro Computer) had its best week since May, surging 24% after raising its Q4 gross margin outlook and reporting a record AI server backlog. KeyBanc called the update meaningfully positive. The stock is still down 40% since June, which tells you everything about how violent the AI hardware sentiment swings have gotten. Bears and bulls are both technically right about SMCI depending on which 90-day window you look at.

The macro backdrop this week was, to put it professionally, a lot. Brent crude crossed $100 per barrel after Houthi strikes hit Saudi tankers in the Red Sea, threatening the Yanbu bypass route that was quietly moving 4 million barrels per day. Warren Pies of 314 Research went on CNBC to say he's overweight both commodities AND equities, and specifically argued the Fed should not hike into this. The FOMC rate hike probability still jumped from 13% to 34% in one week. That spread tells you how divided the smart money is right now.

On the sentiment side, the week's most-discussed YouTube content split into two camps. The AI optimism camp got loud after Jensen Huang's exclusive interviews dropped across every Bloomberg show imaginable, detailing a $500B partnership with SK Group and a $1B investment in Naver. The bear camp, meanwhile, was walking through empty malls in Alabama (shoutout Jeremiah Babe and the Wiregrass Commons food court, which is fully closed and apparently hosting a parking lot that's crumbling). Both camps feel correct, which is peak 2026 energy.

Also worth flagging: $RNG (RingCentral) popped nearly 25% after a Q2 beat and raised guidance, $SLB surged 11% on a Q2 earnings beat driven by international growth, and $AMD CEO Lisa Su was out talking about a $2 trillion TAM for high-performance AI compute over the next four to five years. The Helios rack-scale systems are in full production. OpenAI, Meta, and Anthropic are all committed customers, which either sounds very bullish or very concentrated depending on your mood.

The week's quiet loser? Anyone who thought the AI capex supercycle would get cheaper before it got more expensive. Google's capex hit a run rate that had analysts visibly stressed. The Traveling Trader channel called out Google reporting negative free cash flow for the first time in its history on $44.92 billion in quarterly capex. The market is now asking the uncomfortable question it avoided for two years: at what point does AI spending become a confidence problem instead of a growth story? We'll find out when Meta and Microsoft report next week.
