Salomon Smith Barney

analyst Richard Zandi presented a more sanguine view of online brokers in lieu of recent gains tied to reports of increased trading volumes after a soft third quarter. In a research note, Zandi wrote that although there were reports that trading volume increased in September and October, the online brokers' share of the total

Nasdaq Composite Index

volume actually fell 3% to 28% in the third quarter.

Zandi noted that there could be a number of possible reasons for the change, including a shifting mix of retail and institutional activity and/or the relative resurgence of retail trading activity executed by traditional brokers. But the important thing to take from this, he wrote, is that a key assumption supporting the current market valuation of the online brokers is continued rapid growth. "If this assumption is valid, one would have expected the online brokers' market share to increase despite shifting mixes."

Zandi concluded that fundamental share valuations of online brokers "should be based on long-term estimates of franchise value rather than near-term market volatility."
