This was in response to a Jesse Eisinger column in The Wall Street Journal that heaped negativity on the company. The drop in Commerce's stock, which currently trades around $32 a share, is good news for bargain hunters. My calculations indicate that Commerce will be worth more than double the current quote, or $67 a share, by 2008, and worth triple the current quote, or $100 a share, in four years. Investors interested in the upside opportunity in Commerce stock have to be able to see through the negativity in Eisinger's column. At a minimum, the bulk of the argument is misleading. I'll review where his conclusions go awry.
