Jim Cramer: Stocks That Do Well In a Declining Rate Environment Are Back

"They're back!" writes TheStreet's Jim Cramer, "The stocks that do well in a declining rate environment have come roaring back and the crash of oil will only accelerate the move. It's incredible, what stocks get bought at this moment almost seem literally etched in stone. It's the same group of stocks that starred when rates were first on the way down. There are almost no changed whatsoever. I guess these managers doing the buying feel that the money will be taken away if the declining rate playbook isn't adhered to."

Guilfoyle also looks at the financial sector, Disney's "Star Wars" series, and the sustained growth story that is Splunk (SPLK - Get Report) .
