Citicorp shares lost ground Thursday after Salomon Brothers analyst Diane B. Glossman downgraded them to "buy" from "strong buy." The stock dropped $1.75, to $84.875, on a day in which bank stocks in general posted mixed results. Ms. Glossman said she based her action on price, noting that the stock had appreciated 28.8% for the year. The analyst, who maintained a $99 price target for the stock by the end of the year, said she continues to prefer Citicorp to most other stocks in the banking group. Analyst David Berry of Keefe, Bruyette & Woods agreed that Citicorp, while fundamentally strong, may not merit the enthusiasm it once commanded as an investment. "It's just not the table-pounder it was. At some point, you might find better ideas in the marketplace," Mr. Berry said that a number of analysts have price targets of around $100, which, at the current stock price, makes Citicorp a bit less attractive. "The fundamentals for the bank are great," Mr. Berry said.
