+Shares vs options — what's the difference?
SharesYou own the stock. The return is the underlying's move (entry → exit), linear, and you can hold as long as you like. Steadier, lower leverage.
OptionsYou buy a contract (a call or put at a strike, expiring on a date). The return is on the premium — leveraged (a small stock move can be a huge % on the option) and time-sensitive (value decays toward expiry). Higher risk and reward; here the premium is modeled, not self-reported.
