The Dow Jones Industrial Average closed below 14,000 as technology stock and energy stocks led the markets lower. CNBC's "Fast Money" team considered the drop to be profit-taking and reviewed various downgrades by analysts.Chip stocks traded lower after Morgan Stanley downgraded Intel ( INTC), Advanced Micro Devices ( AMD) and NVIDIA ( NVDA) to underweight. Pete Najarian viewed the downgraded as very interesting, but he feels that PC demand is real. Guy Adami sees it as a gutsy call by Morgan. Mattel ( MAT) and Hasbro ( HAS) traded lower after BMO Capital Markets downgraded the toy sector. In Macke's opinion, the downgrade is about taking gains and he is still long Hasbro and Disney ( DIS) CSX Corp. ( CSX) traded lower after it was also downgraded by Morgan Stanley citing lack of freight volume growth. Adami maintains that $38 is the bottom. He also points out that Carl Icahn and Warren Buffett are long CSX.

Finerman thinks that BEA Systems is one where Icahn can become an active shareholder. She hazards a guess that Icahn will sue BEAS to force them to have an annual meeting. Adami thinks BEAS is going higher with or without Icahn.
