The standard board lot size for trading securities on the Singapore Exchange (SGX) is typically set at one hundred units of shares for most primary equities and listed instruments. This standardized lot size was implemented by the exchange to lower barriers to entry for retail investors, making it significantly more affordable to build diversified portfolios of blue-chip stocks and real estate investment trusts. However, investors should always verify specific counter rules, as certain specialized securities, debt instruments, or low-priced shares may occasionally feature different board lot configurations or odd-lot trading provisions managed through specific brokerage platforms.
