LONDON, Jan 16 (Reuters) - European shares ended little changed on Tuesday as losses among commodity stocks more than offset initial gains due to a series of well-received trading updates.

Engie also gained, rising 1.2 percent after the French utility said it hoped to improve earnings growth in its core businesses of renewable energy, grids and energy services this year. Core earnings rose an estimated 5 percent in 2017.

GKN rose about 1 percent as it faces continued pressure from activist fund Elliott to engage with its would-be suitor Melrose.
