LONDON, July 9 (Reuters) - Shares in Man Group, the world's largest listed hedge fund company, broke a five-day losing streak to surge by around 10 percent on Thursday, making them among the best performers in the UK market.

Traders and analysts cited several different factors for the rebound, including data showing a slight rise in the performance of Man Group's AHL funds and the fact that Man Group's funds may have benefited from a commodity price recovery.

"They are 'long' on commodities which have bounced, benefiting the stock," said Beaufort Securities' sales trader Basil Petrides.

Shares in Man Group rose as much as 11.1 percent to an intraday high of 155.30 pence -- marking its best level in more than a week.

The stock was up by 8.5 percent at 151.80 pence by 0950 GMT, making it the best-performing stock in percentage terms on the FTSE 250 mid-cap index, with trading volumes in the stock above those for the index.

Man Group's shares had fallen by around 10 percent over the last week, with global stock markets hit by worries over Greece's debt crisis and a sell-off in the Chinese stock market.

A Man Group spokeswoman declined to comment when asked about the stock's rally on Thursday.

In spite of the share price rally on Thursday, Man Group's shares remain down by around 5 percent since the start of 2015.

Man Group issued a cautious outlook in May, which took some of the shine off the company's record funds under management levels. (Additional reporting by Nishant Kumar; Editing By Sinead Cruise and Keith Weir)
