Why Your Stock Can Go Up While Your Calls drop
Many beginners assume that buying a call option means making money whenever the underlying stock rises.
Unfortunately, it isn’t that simple.
An option’s price is influenced by more than just the stock price.
Consider this example:
-You buy a call option for $500.
-The stock rises by 2%.
- Implied volatility drops significantly.
- Several days pass, reducing the option’s remaining time value.
Despite predicting the stock’s direction correctly, your option could still lose value.
This happens because three important forces are working simultaneously:
Delta: How much your option changes when the stock moves.
Theta: How much value your option loses as time passes, all else equal.
Vega: How sensitive your option is to changes in implied volatility.
With options, predicting the direction isn’t enough. You also need to consider timing and volatility.
A good prediction can still result in a losing trade.
