stocks vs options

what do you mean convexity? How would it benefit trader?

Imagine a return graph where X is the stock price and Y is the profits. Trading the outrights will have a graph that is a linear function. Long options (long volatility) strategies will have a graph that is an exponential function.

We see that slope of that linear function is a constant multiple.

However, the variable rate of change of that exponential function shows convexity.
