The Weekend Rip
Happy Weekend!

Markets swung through highs, dips, and rebounds this week as AI megadeals, Fed caution, and geopolitical drama dominated headlines. Nvidia’s $100B OpenAI chip deal kicked off Monday’s rally, while Eric Jackson’s BETR pick sparked meme stock mania. Lithium Americas and Opendoor surged midweek on stake news and housing data, but Powell’s remarks cooled sentiment. Trump signed off on the TikTok takeover Thursday, and Friday’s inflation data reassured investors that rate cuts are still on track.

Let's recap and prep you for the week ahead. 📝

◀️ Markets hit fresh highs Monday, driven by Nvidia’s $100B OpenAI chip deal and Eric Jackson’s viral endorsement of Better Home & Finance, which doubled intraday as traders dubbed it the next OpenDoor. Tech led gains while Kenvue plunged to record lows after President Trump linked Tylenol to autism in a controversial NIH directive. Meanwhile, Disney faced backlash over Jimmy Kimmel’s suspension, and Plug Power, Office Depot, and Metsera all surged on bullish news and buyouts.

🌏️ Markets cooled Tuesday as Powell’s cautious Fed remarks and Trump’s fiery UN speech weighed on sentiment, despite strong earnings from Micron and a surge in lithium and defense stocks. Lithium Americas soared on reports of a U.S. stake in its Thacker Pass mine, while BigBear.ai rallied on a Navy partnership and retail traders doubled down on Eric Jackson’s BETR pick. Fed officials warned of labor risks and stagflation, and Trump hinted at a policy shift on Ukraine while urging NATO to confront Russian aggression.

⚡️ Markets dipped Wednesday as investors paused after Tuesday’s highs, digesting Powell’s cautious remarks and Yardeni’s warning of “irrational exuberance.” Lithium Americas surged on news of a potential U.S. stake in its Thacker Pass mine, while Opendoor climbed after Jane Street revealed a $361M position and new home sales hit a three-year high. Robinhood rallied on FINRA’s plan to ease day trading rules, and Alibaba jumped 9% after pledging $50B to AI, joining a wave of mega-cap handshake deals across tech.

🐂 Markets slipped Thursday despite upbeat GDP and jobless data, as investors digested Trump’s Oval Office signing of the TikTok takeover deal and warnings from Citadel’s Ken Griffin about government stake-picking. The $14B TikTok valuation gives the U.S. a 45% stake, with Oracle providing cloud infrastructure, pending China’s approval. Costco beat earnings on strong membership growth, while CarMax missed as used car sales slumped, and PepGen surged 121% on DM1 trial data.

😢 Markets rebounded Friday after inflation data showed prices rising but not enough to derail the Fed’s rate cut path, with every sector closing green despite fresh tariff threats. Trump proposed a 100% duty on drugs not manufactured in the U.S., boosting healthcare stocks, and chipmakers were offered exemptions if they match domestic output. EA surged on reports of a $50B buyout led by Silver Lake and Saudi Arabia’s Public Investment Fund, while a looming government shutdown and OpenAI’s $100B week kept macro tensions high.
