Jim Cramer's Mad Money Lightning Round OT (FTNT, COCO, NAT)

On CNBC's Mad Money Lightning Round OT, Jim Cramer said that investors should not buy Corinthian Colleges, Inc. COCO. He explained that this stock is so low that he is tempted to pull the trigger, but he hates whole for-profit education group. Corinthian Colleges (COCO) fell 0.18% on Friday, and closed at $5.43. Cramer thinks that Nordic American Tanker Shipping Limited NAT is still a buy, because it has a sustainable dividend yield. Nordic American Tanker Shipping Limited (NAT) gained 0.04% on Friday, and closed at $27.05. It is a good a idea to buy Fortinet, Inc. FTNT, believes Cramer. He thinks that this company could become a takeover target. Fortinet, Inc. (FTNT) dropped 2.27%, and closed at $21.51.
