3. Liquidity and Exit Strategy
Remember that SME shares trade in fixed lot sizes (e.g. 1,000 or 2,000 shares per lot). You cannot buy or sell a single share on the secondary market. Ensure you have holding power or trade on listing day through the market maker's 2-way bid-ask quotes.Apply This Research With Live IPO Tools
