B. Riley Financial, Inc. shares fall 1.86% premarket after downgrading ZimVie to Neutral.

B. Riley Financial, Inc. declined 1.86% in premarket trading. The company initiated a buy rating for NN with a $4 price target, which could be seen as a positive move. However, the stock's decline may be attributed to the downgrade of ZimVie to neutral from buy, as well as the investigation into CTO Realty Growth, Inc. by Pomerantz LLP, which could have a negative impact on the company's reputation.
