Mainboard vs SME IPOs: what investors should compare
The listing platform changes the terms you need to check. It does not replace research into the issuer.
Read the offer terms
Check the exchange, investor categories, bid lot, allocation process and listing notices.
Check trading mechanics too
Look closely at application size, trading lots, market-making arrangements and liquidity disclosures.
Compare these questions
| Question | What to verify |
|---|---|
| How much must I apply for? | Current price band, shares per lot, required number of lots and investor-category rules. |
| How will shares trade? | Exchange platform, trading lot, applicable market-making arrangements and current trading notices. |
| Can I exit easily? | Available liquidity disclosures and the risk of limited buyers. A quoted price does not guarantee an executable sale. |
| How reliable is the business? | Financial history, cash conversion, related-party activity, governance and customer concentration. |
A smaller issue needs specific questions
SME issuers may have shorter operating histories, concentrated customers and different trading mechanics. Read the disclosed facts for the particular issuer. Avoid treating a board label, subscription multiple or grey-market quote as a risk score.
Use current rules
Exchange requirements and category limits can change. This guide intentionally does not hard-code minimum investment amounts or eligibility thresholds. Use the issuer’s current offer documents and exchange notices for an application.
