Citi chief Vikram Pandit offered some reassurance to investors and the market, saying the bank has had a strong start to 2009. Nonetheless, U.S. officials are reportedly examining what new steps they might need to take to stabilize

Citi

if conditions worsen for the bank, according to a

Wall Street Journal

report. The Treasury Department already has a 36% stake in the troubled U.S. bank, which dipped below $1 a share briefly last week.

Stocks appeared to get an added boost after

CNBC

reported that Rep. Barney Frank (D., Mass.) believes the uptick rule might be restored within a month. The uptick rule hasn't been in effect since 2007, and some market observers believe that has allowed unfettered short-selling to take down shares. Before the rule was repealed, a short sale could only come after a move higher in a security's price.
