Cramer’s Lightning Round: Oneok is a buy

$Dollar Tree (DLTR.US)$ : “The problem with Dollar Tree is that people I think have discovered that the small form is no longer working, they would rather go to Walmart, which is a buy, or Costco if they can afford the membership fee.”

$ONEOK Inc (OKE.US)$ : “I think Oneok is terrific. I would indeed buy more.”

$DexCom (DXCM.US)$ : “Dexcom had a real bad miss. They still really haven’t fully explained why that is...I’d stay away from Dexcom.”

$CRISPR Therapeutics (CRSP.US)$ : “CRISPR I happen to have a sweet spot for...I would be a buyer of CRISPR.”

$KeyCorp (KEY.US)$ : “Definitely keep Key. Key is very, very strong, a terrific, terrific bank.”
