Assume SPY has the current price of 452. The following weekly options have the corresponding prices and greeks Option Call 450 Call 455 Call 460 Call 465 Price 3.5 1.5 0.5 0.2 Delta 0.7 0.3 0.1 0.05 Theta -0.5 -0.4 -0.2 -0.1 Vega 0.2 0.15 0.1 0.05 olo a. If you buy a call 450 at 3.5$/share and then SPY price goes to 453 right after that, what is your profit? What is the return on investment (RON)?
