The Singapore Exchange (SGX) has witnessed a significant uptick in trading activity from late May to mid-July 2025, with the Straits Times Index (STI) returning 6.2% during this period. A group of 50 stocks outperformed, achieving average and median returns of 31% and 19%, respectively, alongside a notable increase in their combined daily trading turnover. This surge has resulted in tighter bid-ask spreads for most of these stocks.
Sanli Environmental and mDR have been standout performers, with their daily trading activity skyrocketing from approximately S$3,000 to over S$300,000 over seven weeks. This dramatic increase in turnover has led to tighter bid-ask spreads. Other notable stocks, including Cap Allianz, Oxley, Koh Brothers, Addvalue Tech, Banyan Tree, and Stamford Land, also experienced proportional rises in turnover.
Among the 50 stocks, Q&M Dental led institutional inflows, coinciding with a rise in share price, increased CEO ownership, and active share buybacks. OKP, LHN, Boustead, and Grand Venture also recorded significant net institutional inflows.
Sanli Environmental’s trading rank has soared in 2025, with its average daily turnover (ADT) increasing from around S$2,700 to S$83,000 by mid-July. The company recently announced a S$105.3 million contract for the Tuas NEWater plant, expected to boost its FY26 revenue. Meanwhile, mDR’s ADT rose from S$3,400 to S$103,000, with the stock moving up the ranks to become one of the top 150 most traded stocks by July.
The increased trading activity and tighter spreads reflect a dynamic shift in the market, with implications for future trading strategies and investor interest.
