NEW YORK, Nov 6 (Reuters) - Nasdaq OMX Group's (NDAQ.O) third-quarter operating profit met expectations and the company pushed forward the integration of its trans-Atlantic merger, but its shares fell on Thursday as investors locked in profits on one of the better-performing financial stocks.

The operator of the Nasdaq Stock Market got a boost from volatile trading in the period, in which the markets began to spin downward. Operating profit rose 28 percent while revenue from its core transactions business jumped 12 percent.

But the second-biggest U.S. exchange also said it incurred about $70 million in one-time charges. Its shares, which have outperformed those of rivals the last couple of months, fell 10.1 percent, leading a drop in the sector.
