Oct 31 (Reuters) - Derivatives exchange Cboe Global

Markets ( CBOE ) reported a rise in third-quarter profit on

Friday, helped by robust options trading as investors stepped up

hedging amid geopolitical tensions and macroeconomic

uncertainty.

Cboe's adjusted net income rose to $279.8 million, or $2.67

per share, during the three months ended September 30, compared

with $232.9 million, or $2.22 per share, a year earlier.
