Nov 8 (Reuters) - Lyft Inc shares sank 20% on Tuesday on signs that competition from bigger rival Uber was stalling user growth and eating into the market share of the ride-hailing firm.
At least 14 analysts slashed their price targets on Lyft by as much as $23 after its third-quarter results, in stark contrast to the warm reception Uber received after its bumper holiday-quarter forecast.
Active riders on Lyft's platform grew just 7.2% to 20.3 million in the July-September period, the slowest pace this year and a million below market expectations.

Uber, which controls a bigger chunk of the market, posted a 22% rise in active riders.

Lyft's stock was at $11.51 in premarket trading.

It has lost more than two-thirds of its value this year, far more than Uber's 34% decline.
