Buffett’s successor hits his first major stumble: Berkshire’s Google stake is reportedly sitting on a $3 billion paper loss🚨📉 Alphabet has fallen more than 24% since June. But before everyone pins this on Greg Abel, remember: Buffett previously said buying Alphabet was his decision. Abel now has to decide what comes next. Hold through the selloff, buy more, or rethink the position? Google’s reported Q3 earnings miss and negative free cash flow have put its AI spending under the microscope. Investors want to know when those enormous bills will start paying off. Meanwhile, Berkshire’s Class A shares just hit a record high. Its insurance and railroad businesses still matter, and it ended Q2 with roughly $365.5 billion in cash and related liquid assets. A struggling tech position doesn’t tell the whole Berkshire story #Buffett #Google

Purge day on Wall Street 🚨 Two days after Democrats took both chambers, funds are already blowing up. Leopold Aschenbrenner, AI's most famous wonder kid, has had his fund Situational Awareness liquidated. Almost every position in it got cut in half before the end. Memory, GPU clouds, miners turned AI hosts, AI power. $SNDK $CRWV $CORZ $NBIS $BE $MU. He went all in on the full AI infrastructure trade. Here's the problem with leverage. You can be right about the direction and still lose everything. With enough borrowed money, a 40% drop takes you out, and you never get to see the bounce. Let this be the lesson. Never pile heavy leverage into high-risk positions. And he's not alone. The rumor is that Walleye Capital, a multi-strategy hedge fund running about $17B, is blowing up too. It lost 5.9% in October, its worst month since 2020. Today there's talk it's cutting its equity long/short team, firing department heads and planning to hand money back to investors. The full story isn't confirmed yet, but the direction this is heading is really dangerous ⚠️ #Nasdaq100Tumbles6% #AI

Remember when everyone said Microsoft was "too expensive" and "losing the AI race"? Bill Ackman bought it anyway. He's now sitting on roughly $1.1B in paper gains 📈👏 $MSFT ripped almost 7% yesterday to close at $555.80, a new all-time high. Azure growth sped up to 48%, and after the midterms money came rushing back into big tech. Pershing Square opened the position in Q1, at an estimated cost of around $370 a share. Then Ackman bought more in Q2 and now holds about 6.2M shares. That's up roughly 50%. Now Bridgewater. They dumped 34% of their Microsoft stake in Q2, more than 370K shares, right before it took off 🤣 #Microsoft #AI #USMilitary

#USMidterms-WhatAreMarketsExpecting? 🚨Trump lost Congress. His portfolio is still winning Per his filings, his accounts made ~3,600 trades in Q1 2026 alone.

Jensen bought the dip on CoreWeave in January. The dip kept dipping🚨📉 Nvidia put another $2B into $CRWV at $87.20 a share, taking its stake from about 6% to 11.5%. CoreWeave closed at $50.15 on Monday. That's an all-time low, and the stock is down 44% this month. On paper, that $2B is now worth around $1.15B. The worry is the debt. CoreWeave's credit default swaps just hit a record high, and some analysts are already saying "Lehman." Oracle took a hit the same day. It announced a $20B raise and the stock fell 8.8%. Larry Ellison lost roughly $11B in one session #JensenHuang #Aİ #CoreWeave #EarningsSeason

🚨Bill Ackman just went big on Amazon, Meta and Microsoft. Together they're now about a third of his portfolio On the In Good Company podcast, the Pershing Square boss said he's been buying the exact Big Tech names Wall Street dumped over their huge AI spending plans. His logic is simple. A company comes out and says "demand is so strong we have to spend way more than we planned just to keep up"... and the stock drops. To Ackman, that's a gift. How he built the positions: 🔹$AMZN: bought during the panic after Trump's "Liberation Day" tariffs 🔹$META: started buying at the end of 2025 🔹$MSFT: bought in early 2026, paid for by trimming his Google stake #BillAckman #BigTech #AI
