COLOMBO, May 31 (Reuters) - Sri Lankan shares ended weaker on Friday, snapping three straight sessions of gains, as foreign investors sold risky assets and the market shrugged off a widely expected rate cut by the central bank. ** The rupee closed steady, market sources said. ** Before the markets opened on Friday, the central bank cut its key interest rates to support its faltering economy as overall business and consumer confidence slumped in the wake of last month's deadly bomb attacks. ** Traders said the Easter day bombings and aftermath violence, and worries over slowing economic growth weighed on investor sentiment. Most investors have shied away from the market since the April 21 bombings that killed more than 250 people. ** Sri Lanka is unlikely to hit its full-year economic growth target of 3-4% following the Easter Sunday bombings, junior finance minister Eran Wickremeratne told Reuters last week. A Reuters poll has predicted the growth to slump to its lowest in nearly two decades this year. ** The central bank chief said on Friday that he expected the economy to grow by 3% or less this year due to the impact of the deadly Easter bomb attacks, and the bank was preparing a downward revision to its earlier projection for 4% growth.
** The benchmark stock index ended 0.26% weaker on Friday at 5,310.95. It rose 0.3% for the week, recording its second straight weekly gain. The bourse has declined 12.25% so far this year. ** The government's pension fund has resumed investing in risky assets as the stock market is "extremely undervalued at the moment and is considered a good time to go into", the central bank governor said. ** Turnover was 167.8 million rupees ($952,327), less than a third of this year's daily average of around 550.6 million rupees.
