Just noticed Citigroup closed at $106.53 yesterday, down 2.22% - which is actually a bigger fall than the broader market. The S&P 500 only dropped 1.33%, Dow was down 0.95%, and even Nasdaq just fell 1.59%. So C took more pain than the symbol indices.

Looking back a month, Citigroup's down 5.87% while the S&P 500 is actually up 0.58%. The finance sector as a whole is only down 2.34%, so Citigroup's really underperforming its peers. The stock's trading at a Forward P/E of 10.69 versus the industry average of 13.39, which is actually a discount, but clearly the market's pricing in some concerns.

They released earnings on April 14 and the numbers showed EPS of $2.59 (up 32% YoY) and revenue of $22.65 billion (up 4.88%). Full year guidance is looking at $10.2 EPS and $89.86 billion revenue, both up around 5-28% year-over-year. PEG ratio sits at 0.7 versus the industry's 1.03, so valuations look reasonable on paper. Still, the stock's been catching bigger losses than the market symbol-wise, so worth watching what happens next in trading.
