COLOMBO Oct 21 (Reuters) - Sri Lankan shares ended slightly firmer on Friday, edging up from their lowest close in 1 month hit in the previous session, as foreign investors bought risk assets ahead of a flurry of corporate results and next month's national budget.

Sri Lanka's quarterly earnings season started last week but the bulk of locally listed firms will not report until late October or early November.

The national budget is scheduled to be presented on Nov. 10.

The benchmark index of the Colombo Stock Exchange ended 0.08 percent or 5.17 points firmer at 6,447.53, up from its lowest close since Sept. 20 hit on Thursday. The index fell 0.54 percent on the week, its second straight weekly loss.

Turnover stood at 1.15 billion rupees ($7.81 million), the highest since Oct. 3 and more than this year's daily average of around 741.5 million rupees.

"Today the market was a bit positive with some foreign inflows. Even though the quantity was low the foreign interest was there," said Dimantha Mathew, head of research, First Capital Equities (Pvt) Ltd.

Stockbrokers said the stock market was also digesting political concerns over the resignation of the head of Sri Lanka's anti-corruption body on Monday, a few days after President Maithripala Sirisena implied that the agency was favouring the rival party of his prime minister.

This is likely to delay one of the promises of Sirisena's coalition government to eliminate corruption and could hurt business confidence, analysts said.

They have sold a net 1.82 billion rupees worth of shares so far this year.
