The asset manager said it had seen a net inflow of funds of £273m for January and February after surprising analysts with outflows of £143m in the final quarter of last year.
Jeffrey Meyer, chief executive, said Gartmore had seen trends improving since the market bottomed out a year ago and investors were redeeming funds.
Net new business for the year to December 31 was £252m compared with an outflow of £4.88bn a year ago.
