Clearly, there is not much of a difference between the BSM expected
value (shown by the dotted line) and the dot representing a 10 percent

With the longer time horizon, our assumed stock price is significantly
higher than what the BSM calculates as its expected price. If we take “assumed
future stock price” to mean the price at which we think there is an equal chance
that the true stock price will be above or below that mark, we can see that the
difference, marked by the double-headed arrow in the preceding diagram, is the
advantage we have over the option market.

downside exposure will be overvalued and upside exposure will be undervalued.
How, you may ask, can this discrepancy persist? Shouldnt someone
figure out that these options are priced wrong and take advantage of an
arbitrage opportunity? The two reasons why these types of opportunities

(LEAPS)—options with tenors of a year or more—do exist, but
