Here's what CNBC's "Fast Money" traders had to say about some of the market's biggest movers on their "Pops and Drops" segment Monday.
Nationwide Financial ( NFS) popped 26%. Karen Finerman said that buyout activity was responsible for the jump in share price. PowerShares DB Agriculture ( DBA) rose 2%. Tim Seymour attributed the move to a rising emerging market consumer.
Citigroup ( C) dropped 6%. Najarian said excessive banking fears caused the stock to drop. AK Steel ( AKS) fell 10%. Adami said that on a bad day, the steel names underperform. On the other hand, he said investors like Harbinger are accumulating steel names. iShares MSCI Malaysia ( EWM) was down 12%. Seymour said that the Malaysia stock market is down 25% over the past weeks. The recent election wasn't the only factor, he said. He urged viewers to put money into Taiwan. Rio Tinto ( RTP) lost 6%. MannKind ( MNKD) stumbled 10%. Najarian said that as other drugmakers get out of inhaled insulin drugs, investors are getting out of MannKind, the only company still in that business. Blue Nile ( NILE) ticked down 5%. Guy Adami noted heavy short interest in the name.
