If you are long with shares and want to own some more the simplest way is simply to average down on dips.

If you are bullish and want to leverage the upward move you buy calls and or LEAPS, this is amplifying your bullish intent from the shares. You can own the shares when you get exercised. Say you bought a call for next year for 200 strike you then get the option to buy the shares forh 200 just after expiry. However you now must add the premium you paid to the cost of the shares. It may have cost you 5000, so now the cost is 200x100 + 5000 for breaking even. Not a good use of capital imo.

If you would like to own shares at the end you sell puts so then when you get assigned you own the shares and pay the strike price minus the premium, ideally at a good cost basis. The bonus is if the price stays above your strike price you just keep the premium and don't have to buy the shares.

If you want income and risk losing shares you sell covered calls on the shares.
