Only thing, SGX trades lots of 100 shares. therefore to trade that 50 shares need special arrangement with brokerage.
Fractional shares are those that when divided do not make up one whole share, like 0.2 etc that will be the one with issues. @talking bull states a solution in place, I'm not sure.

101625629 : In terms of business efficiency, McD still a winner. Able to turn big chunk of revenue into Net Profits, unlike others in same competition.

101625629 High Profit Low Loss: mixed feedback. still have time, simply buy enough to make round number multiple of 20. cheap share price. Avoid odd lot occurrence altogether. $Seatrium(S51.SG)$ 20 shares become 1 after 8th May 2024; so buying frenzy to avoid odd-lots. Worst part "fractional entitlements to be discarded"
