NEW YORK ( TheStreet) -- When we last spoke about Citigroup's ( C) prospects, the chief concern among investors was with the bank's risk versus its potential reward. Citi was peculiar in a couple of ways.First, the pace of the bank's recovery presented investors with plenty of reasons for optimism. Yet, it was broadly understood from management's own words that there were no "easy solutions." Management was sending cautionary hints that Citi's underlying value was going to take some time to be realized. It seems, though, I was a bit more confident in management than it was. This time, it is the Street that seems to bright-eyed. Citi's first-quarter performance (reported in April) was not what I would call exceptional. But relative to expectations it wasn't that bad. I also felt that management showed enough progress for me to then assign a $55 price target on the stock. Almost two months later, shares reached $53.56 on May 30, gaining almost 20%. With second-quarter earnings due out Monday, investors are wondering if it's time to lock in profits. I still believe that $55 per share is "money in the bank" for Citi, I think we need more realistic expectations with what's likely to be reported on Monday. The Street is looking for $1.17 in earnings per share on revenue of $19.68 billion. This would represent year-over-year EPS growth of 17%, with revenue increasing at almost 6%. First, it wouldn't surprise me if Citi were to reach and/or beat these targets. But it wouldn't shock me if management missed on revenue, either -- it seems a bit too optimistic, especially when compared to the revenue growth estimates for Wells Fargo ( WFC), which is expected to decline by 40 basis points. I don't disagree that Citi's 12% sequential revenue improvement last quarter was a step in the right direction. The overall earnings results still revealed some challenges, though. Management talked about working through "legacy issues," suggesting there are things in Citi's past that are still preventing the bank from fully breaking through. BAC). Let's not also forget that Citi's global reach has come under attack by JPMorgan Chase ( JPM). Management has been working to repair Citi's global presence, while also trying to stabilize the bank's position in the U.S.
