AppLovin's 11% Drop: Why Position Size Matters More Than Price Direction
AppLovin Corp. shares fell 11% in the session that MarketWatch's live market coverage reported on February 20, 2025. The drop came after a stretch of unusually large price moves in both directions.
Louis Navellier said the stock was up 34% the prior week and down 14% in the week of the report. Compounded, meaning each week's change applies to the previous result, those two moves leave the shares about 15% above their level at the start of the earlier week (1.34 × 0.86 ≈ 1.15).
In my view, that pair is best read as volatility, meaning how far and how fast a price swings, rather than as a trend. A 34% gain followed by a 14% loss is not a wash. A round trip of that size in two weeks is the kind of path that punishes anyone sizing a position off a single week's move.
The volatility sits on top of a very large run. On November 4, 2024, AppLovin had risen 310% year to date, which CNBC attributed to FactSet data showing that gain exceeded that of every U.S. tech company with a market capitalization (share price times shares outstanding) of at least $5 billion. Three days later, on November 7, 2024, the shares rose 46% on the Thursday and closed at $246.53. CNBC's report from that day put the stock's year-to-date gain at 519% as of that close.
The November figures are the base against which the February moves should be read. A stock that has more than quintupled in a single calendar year can land almost anywhere, and for a trading desk the question is less whether a double-digit daily move is possible than how often those moves now occur. The February sequence suggests that realized volatility, the swings actually measured in trading, had moved well outside the range a broad index exposure would typically produce. For risk managers, that matters more than any single print, because option-implied volatility (the swing level priced into options contracts), margin requirements (the cash brokers demand to hold leveraged positions), and index weights all respond to the same moves.
For ordinary savers, the lesson is more about position size than direction. A 14% weekly drop erases a large share of a gain that had been widely reported in the financial press, and anyone who entered after the 2024 run would have watched the stock move through dramatic percentage changes within days.
The moves described took place more than 20 months ago.
