- You want lower risk and better liquidity
- You prefer companies with proven track records
Choose SME IPOs if:

Suggested Allocation Strategy
Many experienced investors maintain: 70-80% Mainboard + 20-30% SME for their IPO portfolio. This balances stability with growth opportunity.
Frequently Asked Questions
Which has better listing gains?
