NEW YORK (TheStreet) -- On CNBC's "Cramer's Stop Trading" segment, TheStreet's Jim Cramer, co-manager of the Action Alerts PLUS portfolio, took a closer look at Morgan Stanley's upgrade of Molson Coors Brewing (TAP - Get Report) to equal weight from underweight.
Although the upgrade by itself isn't that exciting, Cramer said "something fishy" appears to be going on, considering that the upgrade has come so late after the stock's price appreciation.
He reasoned that the analyst did not want to have the equivalent of a sell rating on TAP ahead of some potentially big news. Perhaps Altria (MO - Get Report) will sell its stake in Sabmiller, Cramer said.
"There's going to be a deal in this beer world," and it could come within the next 10 days, Cramer said.
