NEW YORK (TheStreet) -- TheStreet's Debra Borchardt is with Jim Cramer, co-manager of the Action Alerts PLUS portfolio, answering the top questions from his Twitter feed. 

Shares of Apple (AAPL) are higher by nearly 2% in Monday's trading session. Cramer says that investors can own the stock at current levels, especially under the aggressive buyback program by CEO Tim Cook. 

He added that Cook wouldn't be buying up the stock in this manner if the company didn't have some great products in the pipeline. "Own Apple," he concluded. 

Turning to the new deal between Yahoo! (YHOO) and Yelp (YELP), Cramer says the former could move higher, especially because of its stake in Alibaba.

He continues to like Yelp because of its presence on social and mobile platforms, which will also benefit Yahoo!. He also reminded investors of Yelp's strong global growth trends. 

Finally, one user wanted to know if Visa (V), Nike (NKE), Starbucks (SBUX) and Boeing (BA) made a good investment combination. 

These are "some of the great growth names of our time. I want to own all of them," Cramer concluded.
