MMM has jumped from 190-195 to 212 range and seems that it is in pullback mode. Same is true for MRK. You can easily cover it at 62.5. These are just suggestions. DYOD.
between 2004 to 2012, my ROR per month was about 4.7% per month. I had a month with 56% up and a month with 38% down. I do not do that crazy stuff anymore. Now it is about 14% to 40% per year. I am trading on 5 different accounts.
it was good to see 50% gain a month but seeing my account drop 30% was very painful. I had 70000 shares of YHOO at 14 and sold it at 16 and then it went to over 40.
