You can
a: Buy 100 share of NVDA at 140
or
b: Buy "2"NVDA leap with strike price of 70 with $80 each.
You dont want to buy "1" NVDA leap, because even though your % of return is 2x of buying the stock, your actual $$ gained is almost the same as buying the stock. It defeats the purpose of going through all the trouble to buy leap.
But buying "2" leaps expose you to higher risk.
Of course, you can choose to buy "1"NVDA leap, and buy another leap of another stock. But the result is the same, basically, when you buy leap, you are using some kind of leverage, and leverage is good in a bull market, and bad in a bear market.
