The Colombo Stock Exchange closed lower on Monday, the All Share Price Index giving up 168.38 points, or 0.81%, to finish at 20,644.26.

Market turnover was Rs. 3.16 billion, EconomyNext reported, citing CSE data. Capital goods led activity with Rs. 1.72 billion — more than half the day’s total — concentrating the session in a single sector.

What moved

The heaviest drags on the index were Ambeon Holdings, down 9.27% at Rs. 32.30, and Citizens Development Business Finance, down 4.61% at Rs. 33.10. LOLC Holdings fell 2.05% to Rs. 430.25, Dialog Axiata lost 1.53% to Rs. 45.00 and Commercial Bank of Ceylon slipped 0.50% to Rs. 201.00.

On the other side, Ambeon Capital rose 3.14% to Rs. 29.60, C T Holdings gained 1.89% to Rs. 540.00, Hemas Holdings added 0.96% to Rs. 31.40 and Distilleries Company of Sri Lanka edged up 0.19% to Rs. 52.90.

The two Ambeon counters moving sharply in opposite directions was among the more unusual features of the session.

Monday’s fall follows a 0.33% decline on 1 October and extends a weak run that saw the index lose about 8% over September.

The reports differ on the S&P SL20

The two newsrooms give different figures for the more liquid S&P SL20 index. EconomyNext puts it down 0.55%, or 32.27 points, at 5,851.23. Hiru News reported it ending at 5,847.02 after a 36.48-point loss — a gap of 4.21 points in both the level and the change, suggesting a different prior-session baseline rather than a transcription slip.

Both outlets agree precisely on the ASPI’s close and its point loss. Hiru rounded turnover to Rs. 3.2 billion.

A third account, filed by Daily Mirror after the close, matches Hiru’s S&P SL20 figures exactly — down 36.48 points, or 0.62%, to 5,847.02 — leaving EconomyNext as the outlier on that index.

Breadth, crossings and foreign flows

Daily Mirror reports that market breadth deteriorated sharply, with just 29 gainers against 171 decliners, an advance-decline ratio of 0.17. Foreign investors were net sellers, with an outflow of about Rs. 112.45 million.

Trading was heavily concentrated. Crossings made up roughly 41% of turnover, led by Access Engineering with about Rs. 622.83 million in block trades and Lanka IOC with Rs. 365.64 million; further crossings were recorded in Sunshine Holdings, NDB, John Keells Holdings, Lanka Milk Foods, WindForce and Watawala Plantations.

Dialog Axiata was the largest drag on the index, followed by Carson Cumberbatch, Commercial Bank, GREG.N and LOLC Holdings. Lion Brewery made the strongest positive contribution.
