Sri Lankan shares fell over 1 percent on Monday, the sharpest in nearly 28 months, as continued foreign selling and concerns about lower economic growth hurt sentiment, stockbrokers said. Foreign investors sold the island nation's risky assets for an eighth successive session, extending the foreign outflow to 841.4 million rupees ($5.32 million). The Colombo stock index ended 1.07 percent weaker to 6,128.34, its biggest intraday percentage fall since March 9, 2016. The index closed lower for 15 sessions in 17, and marked its sixth straight weekly drop last week. Foreign investors net sold equities worth 311.2 million rupees ($1.97 million), extending the year-to-date foreign outflows to 1.64 billion rupees this year.
