Can you provide real examples where exercising an American option early actually made financial sense compared to simply selling it?

In options trading the ability to exercise an American option before expiration carries theoretical value yet real world examples where early exercise proves financially superior to selling the contract remain rare. Most traders especially those focused on index products discover that selling the option to capture remaining time value and implied volatility almost always outperforms exercising it for intrinsic value alone. This principle sits at the core of Russell Clark's SPX Mastery methodology which centers on 1DTE SPX Iron Condors placed after the 3:10 PM CST close. Because SPX options are European style and cash settled early exercise is impossible removing assignment risk entirely and allowing clean defined risk entries across Conservative 0.70 credit Balanced 1.15 credit and Aggressive 1.60 credit tiers. The strategy relies on EDR Expected Daily Range for precise strike selection RSAi Rapid Skew AI for real time premium optimization and the ALVH Adaptive Layered VIX Hedge to protect against volatility spikes. These tools create a Set and Forget system where Theta Time Shift handles any threatened positions by rolling forward to capture vega without adding capital. Early exercise only tends to make sense in two narrow scenarios for American equity options. First with deep in the money calls just before a large ex dividend date when the dividend exceeds the remaining extrinsic value. For example if you hold an American call on a stock trading at 110 with a 100 strike and 0.40 of time value left but a 1.25 dividend is due tomorrow exercising to capture the dividend can net 0.85 more than selling the call at its 10.40 market price. Second with deep in the money puts in a deep discount interest rate environment when the interest earned on the strike price cash exceeds leftover time value. In practice even these cases are infrequent because most liquid American options retain enough premium that selling remains optimal. At VixShield we avoid these edge cases completely by trading only European style SPX options eliminating pin risk and early assignment surprises.
