Tuesday was a gray day, both in and out of the market. Despite a flurry of big headlines, the major indices as they finished the day up just 0.1% as the future of both Citigroup and Bernie Madoff hung in the balance.

Here are some of today’s winners and losers:

Winners

Developers Diversified Realty Corp. (DDR)
Tuesday was another volatile day for the REIT, which managed to regain most of the losses it incurred Monday. Shares closed up nearly 16 to finish the trading day at $6.97, a gain of 95 cents.

Lincoln National Corp. (LNC)
Shares were up Tuesday as the lender prepares to receive government funds and release its fourth-quarter earnings. Shares gained more 14.6% on the day, to end at $20.05 – an increase of $2.56.

Thermo Fisher Scientific Inc. (TMO)
It seems Barron’s was right – TMO may be the stock to buy. The stock slid recently after making a strong climb at the end of last year, but shares closed the trading day up more than 8.5%, gaining $2.93 to close at $37.08.

Varian Medical Systems Inc. (VAR)
A drastic increase in sales helped give the medical equipment supplier a boost. The stock rose 8.4%, or $2.86, to close at $36.92.
