What This Means for Traders

The historical data suggests a pattern where options traders may have consistently underestimated the potential for volatility in Amgen's stock around its earnings releases. While the implied move provides a baseline for expected price swings, the past eight quarters indicate a higher probability of a more significant reaction.

However, the market has also overestimated the move on occasion. On October 30, 2024, an implied move of 5.2% was met with an actual stock change of just 0.2%. Traders often use this type of data on implied versus historical volatility to gauge risk and structure strategies ahead of corporate earnings events.
