GRM InvestmentsThe large purchases by GRM are worth paying attention to, and I have put my money behind theirs in the past and got rewarded. However, even they don't have a crystal ball. The last time I piggy-backed on them with regards to CS, there was a more than 20% decline in share price after the point that they were loading up as they have been in November and December. (They bought about 3x as much in early November as they did at the end of the year. )
