Impressive Option

Near the start of the year (January 17th), I started looking a bit into options.  Not sure if I have the courage to buy such leveraged investments, but I will tell you that when things are going good they can do quite well.  I wrote down call option prices on 24 MFI stocks on the 17th of January.  I tried to pick strike prices that were in the money or almost in the money, to try and be consistent.  Here is how the 24 Options have done in 4 months:
