Activity in the U.S. service sector unexpectedly grew at a faster rate in the month of October, according to a report released by the Institute for Supply Management on Wednesday.

The ISM said its non-manufacturing index climbed to 59.1 in October from 56.9 in September, with a reading above 50 indicating growth in the service sector.

The increase by the non-manufacturing index came as a surprise to economists, who had expected the index to dip to 56.5.
