I was a little surprised this morning when markets opened and Computer Modelling Group (CMG on the TSX, or OTC:CMDXF) was down about 10%. A quick scramble for news revealed that the company reported earnings, and a glance at earnings showed pretty solid growth (in my mind). After a quick update to my model I realized that nothing has changed (to my investment thesis, anyway) and I bought more shares, increasing my position by nearly 130%. I was only holding a partial position at the start of the day, so the decision to buy more when shares were on sale was fairly easy
I may have lost out on $0.30 to take the time to conduct my hurried analysis, but I'm glad I pulled the trigger - shares closed over $1 above my purchase price.
