The nation's fourth largest brokerage firm, Lehman Brothers (NYSE: LEH), reported its August 31st quarterly results this morning. Investors began to breathe a sigh of relief as the numbers beat Street's expectations posting $1.54 earnings per share versus the expected $1.43 EPS. Earnings were 3% lower from last year's results, which were accomplished in an accelerating environment.

Lehman Brothers acknowledged a $700 million hit from "substantial value reductions" in mortgage-backed securities. The investment banking and retail brokerage fees were up 3.1% for the quarter and total revenues were $4.3 billion. Lehman Brothers stated that 53% of its revenue totals came from overseas activities, helping to absorb mortgage-backed securities losses.

Lehman Brothers, once known as a pure trading house, has diversified its revenue stream substantially. Coupled with more than 50% of its revenues coming from international sources, the giant firm has shown it can weather the credit-storm.

The stock is up over 4% today on the relief factor. The next few days will see Bear Stearns (NYSE: BSC), Morgan Stanley (NYSE: MS) and Goldman Sachs (NYSE: GS) report their August results as well. If Lehman Brothers is any indication, investors may again feel these stocks have come down too much and begin nibbling away on the buy side. The only remaining significant issue is the credit markets and if they have indeed calmed down. If so, the leverage in the business model of the major four firms could begin to re-accelerate earnings in 2008.
