Jim Cramer explained his position on FANG stocks Monday, while answering viewer questions from social media. Cramer, the portfolio manager of Action Alerts PLUS, said the FANG stocks are anointed stocks that people will buy on the way down.  But he added, that doesn't mean the stocks are going to go up.  'They have great growth, and there's not that many companies with great growth. That's not a reason to buy them. It's a reason why people are buying them,' said Cramer, who is also host of CNBC's 'Mad Money.' Cramer said it's okay to own one of the FANG stocks, but not all of them. The Action Alerts PLUS portfolio has a big position in Facebook(FB) and also has a small position in Alphabet(GOOG).  Cramer was asked if he likes Seritage Growth Properties(SRG), a Warren Buffett holding. Cramer responded that there are better real estate investment trusts, and he's not excited about.  On the retail front, Cramer was asked about Home Depot(HD) and he suggested buying Newell Rubbermaid(NWL), which has a lot of products sold at Home Depot stores. He also said Action Alerts PLUS has been buying shares of Stanley Works(SWK). A viewer was asked whether to buy FedEx(FDX) or UPS(UPS), and Cramer said to wait for FedEx's earnings report this week before deciding. Energy was a focus of some questions, with Cramer being asked about Devon Energy(DVN) and Transocean(RIG). He responded that he doesn't like either one of those names. Cramer commented on Ciena(CIEN), saying he was surprised by how weak the company's quarter was. He said Ciena has been inconsistent and seems dicey. He added that he likes Cisco(CSCO) because of its valuation and its good yield. Cramer was also asked about Harman International(HAR), and he said the stock will face some headwinds from Apple's(AAPL) expected move into the car market.  On another topic, Cramer said he still likes MasterCard(MA) and Visa(V) very much, and they are two well-run companies. He said if you own the stocks, you can add to your position on weakness. But Cramer added he prefers PayPal(PYPL) in the group. With the start of this week's Federal Reserve meeting approaching, Cramer was asked about what would happen if the Fed doesn't raise rates. He thinks the market will react negatively, with investors believing the Fed is more worried about the economy. Cramer doesn't want the Fed to raise rates.
