Good point! There may not be any profit for people who buy calls with very high implied volatility and then want to sell them after volatility collapses following a major event. For example, the $17.50 call expiring next Friday was priced at $2.225 at the close two days ago. If you buy that call for $2.00 you will need the share price to be $19.50 on Friday just to break even.
