>> Stocks trade to five decimals (subpennies) primarily for penny stocks and low-priced securities to capture tiny price movements (sub-pennys), increasing liquidity and precision, especially when the minimum tick (one cent) isn't small enough to reflect true market dynamics, though it adds complexity and isn't standard for most major stocks. This finer granularity helps reduce the bid-ask spread, benefiting small investors, but specialized brokers and platforms are often needed.
