NEW YORK (TheStreet) -- We've been buying Walgreen (WAG) , Jim Cramer said on CNBC's "Cramer's Stop Trading" segment. He was referring to a move by his charitable Action Alerts PLUS portfolio, of which he is co-manager.

However, Cramer admitted that Walgreen has been a tough stock to own, especially after management said it would not relocate its business for tax inversion purposes.

But Friday had good news in store for the bulls. September same-store sales rose 7.9% vs. expectations for a rise of 5.3%. Pharmacy same-store sales rose 11.3%, while estimates predicted an 8% rise. 

This is the "first real beat" that the company has had in a long time, Cramer said. 

Headwinds for the company seem to be "dying down," while prescriptions appear to be rising.

That's good for Walgreen, he concluded.
