NEW YORK (TheStreet) -- It's Monday again, which means TheStreet's Jim Cramer is with Debra Borchardt, answering questions from his Twitter feed. 

Addressing Celgene's (CELG) recent decline, Cramer said investors could still buy it. 

Despite its rapid selloff, the stock is still up almost 90% so far this year and should continue to go higher, he also said. 

Switching to a discussion of natural foods, Cramer said Sprouts Farmers Market (SFM) reported a great quarter, but he said he wouldn't be a buyer as long as Whole Foods Market (WFM) continues to struggle.

Lastly, he suggested investors should sell Ford (F) if CEO Alan Mulally decides to leave the company for Microsoft (MSFT). 

Cramer said he would be a buyer of Microsoft and seller of Ford should such a leadership move play out.

Action Alerts PLUS, which Cramer co-manages as a charitable trust, had no positions in stocks mentioned.
