I just read somewhere that said any stock position can be replicated with options, and then it went on to talk about how it's advantageous to do so with options instead of buying stock. What's this all about? So like if want you be long a stock do you just buy a call instead? How would you determine what strike price makes your position equivalent to having bought shares instead? I guess the difference would be your long stock position lasts forever and your option expires eventually. Was whoever said this crazy or is there a reason why one would want to use options instead of stocks for general positions?
