The Singapore Exchange (SGX) has reported a successful uptake of its new 10-share lot trading system, implemented on 5 October. This initiative, aimed at enhancing trading flexibility and accessibility, saw more than 20,000 trades executed in 10-share lots across the first 11 selected stocks, surpassing the 13,000 trades in the traditional 100-share lots.
The revised board lot framework, which reduces the minimum trading size from 100 shares to 10 shares, was applied to stocks including DBS Group Holdings, Jardine Matheson Holdings, and United Overseas Bank. Notably, DBS led with approximately 5,000 trades in 10-share lots, whilst Jardine Matheson Holdings recorded the strongest adoption, with about one-third of its trades executed in these smaller lots.
The initiative allows investors to manage their portfolios with greater precision, enabling them to stage entries, average costs, and rebalance portfolios more effectively. For instance, an investor could accumulate a 100-share position in DBS through multiple 10-share transactions over a trading day.
Trade data from 5 October revealed that 10-share lots were the most common trade size in nine out of the ten actively traded stocks, with Keppel being the exception. The data also showed that around 55% of trades were executed in sizes below the previous 100-share board lot.
Despite a slight decline in overall market turnover, liquidity for the selected stocks remained stable, with eight out of the 11 stocks recording higher average daily turnover in the second half of 2026 compared to 2 October. This indicates that the new system has been well-received, offering investors increased flexibility in their trading strategies.
