While every earnings season allows publicly traded companies to deliver market-shifting news, an underlying dynamic exists that many (if not most) retail investors are largely unaware of. For optionable securities, the derivatives arena often sees heightened expectations of stock movement known as implied volatility (IV). This metric is often stacked against the historic (or realized) volatility, which measures how much the price actually moved in the past.
When large enterprises such as semiconductor giant Nvidia (NASDAQ:NVDA) report their earnings, their stock prices usually jump around more than normal. In some cases, the expectation is for a robust swing northward. In others, market makers anticipate a corrective spell. These short, unpredictable movements raise the premium that the underlying options command, as traders are willing to pay more for protection or speculation.
