But why might Citigroup be reverse-splitting in the first place? Many institutional investors -- e.g., mutual funds and pension funds -- have investment policies that prohibit them from owning stocks priced below $5.00. Citigroup stock plunged below $5.00 in January 2009. Since then, it has closed at or above $5.00 only during two brief periods, first in August 2009 and again in January 2011. It has been trading between about $4.40 and $4.60 since mid-March.
As you can see, Citigroup's institutional ownership is lower than other large U.S. banks:

But according to Morgan Stanley, more than half of the 236 reverse splits it studied underperformed the market for several months after the split. (That said, Morgan Stanley found a small number of those stocks had significantly outperformed the market six months after the reverse split. That's consistent with the theory about expanding the pool of potential investors.)
Looking longer term, conclusions from an exhaustive 2008 study of 1,612 reverse splits that occurred between 1962 and 2001 were emphatically negative. The study stated, "These stocks record statistically significant negative abnormal returns over the three-year period following the month of the reverse split." In plain English, odds are a reverse split is a good sell signal for a three-year horizon.
That’s because reverse splits occur when the company is financially distressed, and financial performance tends to stink for years.
The study went on to warn that "the market underestimates the future poor performances of reverse stock splits." But shorting these stocks is risky. The study favored the idea in theory but concluded reverse-split stocks have characteristics that make them particularly difficult to short.
There's a lot I don't like about Citigroup, including the quality of its management, earnings, and balance sheet. The reverse split looks like one more sell signal for this TARP poster bank.
But there are two sides to every trade … who's buying the stock and why?
