Post-Midterm AI Selloff Triggers Leveraged Unwind, Wall Street Calls Bottom and Eyes Year-End Rally

A leverage-driven AI selloff hit markets after the midterms, but strategists now call it a positioning reset, not a structural break. Seasonal tailwinds and reset valuations have banks reloading equity exposure.

U.S. stocks surged on Monday November 9, with the S&P 500 up 2.36%, the Dow climbing 1,120 points (+2.18%), and the Nasdaq 100 jumping 3.39%. The rally came just days after a sharp AI-sector selloff triggered by midterm election results and fears of tighter data-center regulation under a newly empowered Democratic majority. Investors treated the dip as a buying opportunity, snapping up beaten-down tech names.

Wall Street's consensus is forming quickly: the selloff was a leverage-unwind event, not a fundamental repricing. JPMorgan's Dubravko Lakos-Bujas described it as a forced deleveraging episode — margin debt had been running near record highs since summer, and the midterm shock gave overleveraged positions the push they needed to liquidate. The bank maintained its S&P 500 year-end target of 8,000 and noted that the position cleanup created attractive entry points, particularly in hyperscaler stocks where computing capacity constraints support pricing power. BlackRock's Rick Rieder dismissed the AI bubble narrative outright, calling the selloff a "rebalancing" driven by sector concentration and hedge fund de-risking rather than deteriorating fundamentals. He argued some AI-adjacent names are now genuinely cheap even after baking in downward revisions to growth and capex spending. HSBC's Max Kettner echoed the sentiment, disclosing that the bank had added tactical equity exposure and shifted back to overweight on U.S. stocks, pointing to Nvidia earnings and Anthropic's IPO as near-term catalysts. Seasonal data heavily favors bulls. BlackRock's analysis shows that since 1970, the S&P 500 has averaged a 14% gain in the six months following midterm elections — more than double the 6% average in non-midterm years. Separately, Knode Wealth Management data shows November averaging +1.85% since 1950 (the best month of the year), while Yardeni Research finds December has been positive 70% of the time since 1928. Ned Davis Research's proprietary momentum gauge triggered a sell signal during Thursday's rout but flagged a likely near-term reversal. Independent tech analyst Luke Lango offered a more nuanced take: while the bounce could prove to be a dead-cat bounce, the market's fears about AI capex collapsing are overblown. Any data-center slowdown is politically imposed, not demand-driven. "Spending is being stretched out, not cut off," he wrote, adding he remains bullish on a 3-5 year horizon but cautious over the next 3-6 months. The week ahead carries material risk. October CPI data drops Tuesday and will shape the Fed's rate path through year-end. Producer price data follows Friday. Multiple Fed officials are scheduled to speak, and key earnings reports are pending. If inflation prints hot, the narrative of a valuation-driven rally could reverse quickly — rate-sensitive leveraged positions would face renewed pressure just as they were re-established. The structural question beneath the noise is whether AI investment represents genuine productive capacity expansion or a leveraged speculative cycle dressed in capex clothes. The fact that the selloff was triggered not by deteriorating AI demand but by political risk to data-center buildout suggests the underlying demand thesis remains intact. But margin debt near records, sector concentration, and the speed of the bullish consensus re-forming all point to a market that is structurally fragile even when the direction is up.
