(Dow Jones) LPL Financial Corp.'s IPO may accelerate consolidation of the broker-dealer industry, some experts say.

Others caution, however, against inferring too much from the initial public offering's outcome because of the Boston-based firm's unique business model.

Parent firm LPL Investment Holdings Inc. went public on Thursday in the shadow of General Motors' much-ballyhooed IPO. LPL's offering of 15.6 million shares was priced at $30 a piece on the Nasdaq under the symbol LPLA, which was at the high end of its proposed offering range of $27 to $30. Shares opened at $33.05 and reached a high of $33.84 before closing at $32.15. The stock dipped to about $32 a share in late-morning trading Friday.

With the IPO, the stakes of private-equity firms Hellman & Friedman LLC and TPG Group, will fall to about 32% each from their current 36.3%.

Having a publicly traded stock will make it easier for LPL to continue its strategy of growth through acquisition, said Doug Dannemiller, a senior analyst at Aite Group. The valuations of smaller private brokerages are two or three times revenue, while larger publicly traded firms get a higher multiple, Dannemiller said. "This sort of makes the acquisition process more efficient for LPL," he said. "It can take advantage of that multiple arbitrage between small firms and large."

LPL also could enhance its already impressive ability to recruit advisory teams and individual advisors, he said.

Dannemiller sees broader consequences: There are currently thousands of independent broker-dealers, and "I can see the pace of those smaller, successful firms getting merged up and acquired into the biggest structures accelerating, with firms like LPL having publicly traded stock on the scene and being sort of a serial acquirer," he said. "More buyers will probably raise the valuations across the spectrum."

LPL is much larger, however, than most brokerages, with 12,017 advisors spread nationwide and advisory and brokerage assets of $293.3 billion as of Sept. 30. Its offices have their own brands, with LPL ownership generally only evident in the common technology, product and service platforms and other support.

Private-equity firms are already showing more interest in the brokerage industry, noted industry analyst Bing Waldert of Cerulli Associates. But he doesn't believe many broker-dealers can or will grow as fast as LPL has.

"The independent broker-dealer business is a very, very low-margin business," he said. "I don't know that there are a lot of large acquisition targets out there, but certainly, there's room for a lot of acquisitions of small firms that would be coming out of a pretty tough market, and probably pretty anxious to get out of the business."
