So I've been seeing a lot of traders get caught off guard by early assignment, and honestly it's one of those things that can wreck your position if you're not prepared for it.

Here's the thing: when you're short an options contract, the buyer can exercise it before expiration. Most people think options only settle on expiration day, but that's not how it works. If you sold a put, you could end up having to buy 100 shares at the strike. If you sold a call, you might be forced to sell 100 shares. That's the early assignment risk you need to watch for.

Early assignment doesn't happen randomly though. It usually shows up when an option is deep in-the-money and there's barely any time premium left. The real kicker? Ex-dividend dates can trigger it too. Traders will sometimes exercise call options early just to grab the dividend payment.

Let me walk through a real scenario. Say AAPL is sitting at $171. A $185 put is trading at $14.00 with zero time premium left. That put is getting assigned. Period. But if you're looking at the $175 put at $5.70 with $1.70 of time premium remaining, you're probably safe. The early assignment risk is way lower because there's still value in holding the contract.

Here's where it gets serious: if you're the option seller and you get assigned, you have to fulfill your obligation immediately. If you don't have the capital sitting there, you could face a margin call. That's not theoretical—that's real money at risk.

Credit spreads make this even trickier. Say you sold a 100-95 bull put spread and the stock drops to 90 near expiration. If assignment hits your short 100 put, you can exercise your long 95 put and offset the position. But if the stock is trading between 95 and 100 at expiration, that's when early assignment risk becomes a real headache.

One more thing: most brokers will automatically assign any in-the-money options on expiration day anyway. So whether it happens early or at expiration, if you're short an ITM contract, you need to have a plan.

The bottom line is this—early assignment risk is something every options trader needs to understand and actively manage. It's not flashy, but it's the kind of risk that can blow up your account if you're not paying attention. Make sure you understand your broker's assignment rules, keep enough capital available, and always know what happens if you get assigned. Options can be powerful, but they require respect.
