Actually I am not sure that the comparison will prove if Norm has been of benefit or not. I have taken him to task several times for making the same mistake in his estimates. He repeatedly overestimated the bank's ability/willingness to "write in" income based on overstated reserves for loan losses.
However, I found the rest of his estimates and opinions quite valuable. He chose to play calls at a 20 strike but I took his info and confidently sold puts at 23 and 24.
Money in the bank.
I agree with the notion that one could go back and read prior postings to determine whether a poster knows what is going on. Norm's estimates have been high but his insight into an enterprise that was clearly a good investment 18 months ago was valuable.
