(Reuters) - Shares of UK's Auto Trader climbed more than 13% to a record high on Thursday, after the company posted a bigger annual profit due to healthy demand for and quicker sales of used cars.

The stock was set for its biggest one-day gain in two-and-half years and was the top gainer on London's blue-chip FTSE 100 index.

For the year ended March 31, Auto Trader reported a 26% jump in operating profit to 348.7 million pounds ($443 million).

Its revenue increased 14% to 570.9 million pounds, helped by quicker sale times than before the pandemic and a steady uptake of additional products and services. ($1 = 0.7876 pounds)
