Shearson Lehman Bros. Holdings Inc. said first-quarter earnings rose slightly and revenue jumped 47%, which the brokerage giant attributed partly to its post-crash purchase of E. F. Hutton Group Inc. Wall Street analysts said the results were respectable, considering the enormous trading losses suffered by many firms after the Oct. 19 stock market collapse, including those of Hutton, which was acquired late last year. The parent of Shearson Lehman Hutton Inc. said earnings totaled $81 million for the three months ended March 31, up 2.6% from a year earlier.
