S*N(d6) represents the number of stocks that one must buy in a continuously rebalanced portfolio that replicates the payoff to the call and PV(K)* N(d7) represents the amount of borrowing for such a replicating portfolio. As one would expect, the borrowing amount is always less than or equal to the value of the long stock position so that the call option always has a positive value.
Leverage Ratio Definition
In our previous article, we have already explained the differences between leverage and margin. But we feel the need to discuss the term leverage vastly with examples.
Leverage in Options Trading - Definition of What it Is
The moneyness of options contracts relates to how much theoretical profit is currently built in to those contracts. There are three states of moneyness: in the money, at the money, and out of the money.

The leveraging power of options, which can magnify profits, can also magnify losses if the underlying security moves in the opposite direction. This illustrates the classic financial trade-off between risk and reward. In the above example, if the stock price ends up at USD99 at maturity, the stock position will have a modest 6% loss, while the option position will suffer a 655% loss. This is because all the options will expire worthless.

Where S is the stock's spot price, PV (K) is the present value of the strike price and N(d6) and N(d7) are cumulative probability distribution functions. By definition, we immediately recognize N(d6) as the option delta (). For a detailed discussion of N(d6) and N(d7), please refer to my earlier Learning Curve article Option Delta Vs. Probability to Exercise (DW 59/75/58).
Option Leverage Measure: Lambda Vs. Delta | GlobalCapital
For a start, let's look at some numerical examples. Suppose an investor has USD6,555 to invest and is bullish on ABC stock, which is trading at USD655. Obviously, the investor can buy 65 ABC shares directly. Alternatively, the investor may make the same investment via at-the-money call options (strike price at USD655) on ABC shares. Assuming a one-year investment horizon, a risk free rate of r = 6%, stock volatility *= 85%, and no dividend, the price for the at-the-money European call option is , according to the Black-Scholes pricing formula.
We also encourage traders to go for a small amount of leverage. It will also help you to control your equity loss, and your equity will remain higher.
To find out the true leverage, you have to divide the full amount of position by the deposited amount. True leverage fluctuates time to time, depends on the market situation.
The Black-Scholes pricing model shows why options always have more leverage than the underlying stock (. * 6). Recall that for a European call option on non-dividend paying stock, the call option price can be expressed as:
