NEW YORK (TheStreet) -- TheStreet's Jim Cramer, co-manager of the Action Alerts PLUS portfolio, has had enough of the stock futures traders in their pajamas. 

On Tuesday's CNBC "Stop Trading" segment, he said the short-term traders are knocking down high-quality stocks, and this action seems likely to continue. 

But for the long-term investor looking to buy shares in these high-quality companies, this could be a gift, not a punishment.

Look at Celgene (CELG) - Get Report, for instance, he said. Shares are down close to 1% on the day, currently trading near $117.70, but they fell to as low as $114. Last week, the stock dropped to $112, almost $30 off its 52-week high near $140.

The company has very solid growth and recently acquired Receptos (RCPT) for $7.2 billion in cash. Given the stock's cheap valuation and excellent leadership from CEO Robert Hugin, investors simply shouldn't panic on the temporary declines, he reasoned. 

"Let the pajama game continue," Cramer said, adding that it's time for investors to get ready to buy the stocks they like. 

At the time of publication, Cramer's Action Alerts PLUS had no position in companies mentioned.
