Sri Lankan stocks rose for the sixth straight session on Friday to hit their five-week high led by banking and beverage shares, but foreign investors exited from risky assets with the start of presidential poll campaigning. The rupee currency ended weaker.

Sri Lanka's central bank left its key rates unchanged on Friday after loosening policy earlier this year, although growth is likely to remain subdued as the economy faces rising global risks.

The benchmark stock index ended 0.35% firmer at 5,834.66, rising for the sixth straight session to its highest close since Sept. 5. The bourse rose 2.54% for the week. So far this year, the index has dropped 3.6%.

Equity market turnover was 1.13 billion Sri Lankan rupees ($6.26 million), nearly double of this year's daily average of about 659 million rupees. Last year's daily average was 834.0 million rupees.

Foreign investors were net sellers for the eight straight session. They sold a net 46.4 million rupees worth of shares, extending the year-to-date net foreign outflow to 3.7 billion rupees of equities, according to index data.

Meanwhile, the rupee fell 0.1% weaker at 180.65/75 per dollar compared with Thursday's close of 180.50/65. The currency is up 0.4% for the week and 1.1% so far this year.
