Upstart Plunges 11.2% Amid Fintech Sector Turbulence—Can AI-Driven Lending Rebound From a Sudden Sell-Off?

Summary
• Upstart (UPST) slumps 11.2% to $61.20, its lowest since March 2024
• Intraday range of $61.00–$67.10 highlights sharp volatility
• Options activity surges with 163,000 contracts traded, triple average volume
• Fintech peers like Affirm (AFRM) also under pressure post-Klarna IPO
Today’s selloff in Upstart reflects a confluence of sector-wide jitters and bearish options positioning. The stock’s collapse follows Klarna’s market debut, which has triggered a reevaluation of buy-now-pay-later models. With $13.5 million in turnover and a 16.2% turnover rate, liquidity is surging as traders bet on a potential $60 support test.

Options Volatility and Sector Crosscurrents Trigger Sharp Correction
The 11.2% drop in UPST stems from a perfect storm of bearish options positioning and sector-wide sentiment shifts. Financial institutions have executed 44 unusual trades, with 45% bearish bias. The $68.00 put sweep ($260K) and $135.00 call sweep ($156K) signal institutional hedging against a potential $60–$65 range contraction. Meanwhile, Klarna’s IPO-driven rally has forced investors to reassess fintech valuations, with Upstart’s AI-driven lending model now facing scrutiny amid broader macroeconomic concerns.

Consumer Finance Sector Under Pressure as Affirm Slides 4.6%
The Consumer Finance sector is broadly under pressure, with Affirm (AFRM) down 4.6% as investors rotate out of buy-now-pay-later models. Upstart’s 11.2% drop mirrors sector-wide anxiety over regulatory risks and margin compression. While Affirm’s 20-day moving average remains supportive, Upstart’s 200D MA at $62.38 suggests a critical inflection point. The sector’s 50-day put/call ratio of 1.19 indicates bearish positioning, with Upstart’s options activity amplifying the trend.
