新交所调低买卖单位：11只股票每手由100股降至10股，小额投资者入场门槛下降
新加坡——新加坡交易所（SGX）10月5日将11只股票的每手买卖单位从100股调低至10股，其中包括星展集团（DBS）、华侨银行（OCBC）和大华银行（UOB）三大本地银行股。每手股数下降，意味着买入一手所需的最低金额同步下降约九成，小额投资者参与蓝筹股的门槛显著降低。
以银行股为例：三大银行股价今年屡创纪录，星展的市值在7月突破2000亿新元，成为新加坡首家达到这一量级的上市公司。股价越高，每手100股的入场金额就越劝退初次入市者。调低买卖单位后，第一次买股票的散户可以用小得多的金额开始——这正是新交所近年振兴本地股市、扩大散户参与的一系列措施之一。
市场人士指出，买卖单位改革的效果要结合成交与开户数据观察：门槛降低并不自动带来买盘，但它拆除了一个具体的结构性障碍。对长线储蓄者而言，能以10股为单位分批买入高价蓝筹，也更容易做定期定额的组合安排。
巧的是，新规生效仅两天后，新加坡银行股就遭遇了今年最猛烈的一轮抛售（见10月7日报道）。分析人士提醒，入场门槛与股价风险是两回事：一手变小了，波动一分不少。新交所与券商的投资者教育材料均强调，初次入市者应先理解所买公司的基本面与自身的风险承受能力。

SGX Cuts Board Lot Size: 11 Stocks Drop from 100 Shares to 10 Per Lot, Lowering the Entry Point for Small Investors
SINGAPORE — The Singapore Exchange (SGX) on October 5 reduced the board lot size for 11 stocks from 100 shares to 10 shares, including the three local banking giants — DBS Group, OCBC and United Overseas Bank (UOB). A smaller lot cuts the minimum ticket for one board lot by roughly ninety percent, significantly lowering the entry point for small investors to own blue chips.
The context is the banks' extraordinary run: Singapore bank shares hit record or near-record levels this year, and DBS crossed S$200 billion in market capitalisation in July, becoming the first Singapore-listed company to reach that level. The higher share prices climb, the more a 100-share lot deters first-time buyers. With lots of 10, a new retail investor can start with a much smaller sum — the change is one of a series of measures to rejuvenate the local equities market and broaden retail participation.
Market watchers say the reform's effect will show up in turnover and account-opening data over time: a lower threshold does not automatically create buying, but it removes a concrete structural barrier. For long-term savers, being able to accumulate expensive blue chips in 10-share units also makes regular, fixed-amount investing easier to run.
By coincidence, just two days after the new lots took effect, Singapore bank stocks suffered their sharpest sell-off of the year (see the October 7 report). Analysts note that entry size and price risk are different things: a smaller lot does not shrink volatility. SGX and brokers' investor-education materials alike stress that first-time buyers should understand the company they are buying and their own risk tolerance.
