# Gamma

Looking at the hypothetical example, XYZ is trading at $50. The XYZ Jan 50 call is trading for $2, has a Delta of .50 and a Gamma of .06. Should XYZ go up to $51, an investor can estimate that the 50 strike call will now be worth around $2.50. The new Delta of this 50 strike call at an XYZ price of $51 should be around 0.56 (simply adding the Gamma of .06 to the old Delta of .50).
