How much more leverage am I taking with this option compared to just buying the stock?

How this is calculated

• Effective leverage equals delta multiplied by the stock price, divided by the option premium. This estimates how many times more sensitive your option's value is to a percent move in the stock, compared to owning the stock directly with the same dollar amount.
• This is the same figure options traders sometimes call leverage or elasticity: for roughly every 1% the stock moves, the option's value moves by roughly this many percent, near the current price.
• Share-equivalent exposure per contract equals delta times 100, since one standard equity option contract represents 100 shares.
• This estimate only holds near the current price and the current moment. Delta itself changes as the stock moves (that's gamma) and the option's value also erodes over time from theta decay, neither of which this leverage estimate captures.
• Higher effective leverage means larger percentage swings in both directions, gains and losses. A cheap, far out-of-the-money option with a small delta can carry very high effective leverage precisely because it's cheap, not because it's a safer trade.
