While Citigroup ( C) is traditionally one of the most active stocks on the NYSE, it's been getting special attention lately. That's thanks to the brief flirtation with new 52-week highs that shares of Citi made at the beginning of the new year. Now, with shares decisively lower following a fourth-quarter earnings miss more than a month ago, Citi shareholders need to be playing defense. Following Citi's earnings miss in late January, shares gapped down to the sub-$5 range, consolidating for just over a month as market participants determined the direction for this stock. At the end of February, shares cracked below support and have since been consolidating at the stock's next lower level. Right now, trader bias toward Citi is on the short side. Following two lower bouts of consolidation, this banking giant has two overhead resistance levels to surmount before it can make another attempt at those previous highs. Meanwhile, with support at $4.50 and little else below it, a fall below that support level could send shares to the 200-day moving average. Caveat emptor. Among Citigroup's major holders is George Soros , who increased his stake in the stock in the most-recent quarter, and Citi is one of 10 stocks that matter most to hedge funds.
