Hi...kind of new to options trading, so sorry if this is a dumb question.

My understanding is that a call option becomes more expensive the closer the strike price is to the current price.

For example, for a $100 stock, the price of a $101 option would be more expensive than a $105 option since the stock is more likely to be in the money at expiration.

But for some option chains, I'm seeing the reverse: an option with a higher strike price being MORE expensive than one with a lower strike price.

Why would this be?
