Most of the S&P 500 has reported Q4 results now and things look decent. Earnings growth is tracking at 13%, largely driven by tech companies. However, there were some major moves in individual names this week. * **Kyndryl** plummeted 42% after delaying their 10-Q filing and announcing the CFO is leaving. * **MicroStrategy (MSTR)** dropped 17%. Bitcoin volatility hit them hard, resulting in a $12.4 billion net loss and $8.9 billion in unrealized crypto losses. * **Monday.com** fell 14%. They beat earnings and revenue estimates, but the guidance was weaker than Wall Street wanted. * **Estee Lauder (EL)** dropped 10%. They beat estimates but tariff issues are weighing on the stock. * **Peloton (PTON)** is down 9%. Revenue missed expectations and subscriptions dropped 7%. * **On Semi (ON)** fell 7% after missing earnings estimates and providing weak guidance. * **Chegg (CHGG)** dropped 5%.
