Is it worth investing in small caps

My two cents on Small caps investing based on last 2 years of experience :

1. String Industry tailwind – mostly India structural story based tailwinds
2. If possible , look for monopoly / oligopoly sectors
3. Good track of Business scale up in last 10 years from micro to small cap journey
4. Capex lined up in next 2-3 years
5. Low debt preferable
   6.Valuaation cap at 20 PE . Exceptional cases can be looked for 35-40 PE maximum.
6. Weekly Chart should not be too discouraging
7. Last but the most important point – a portfolio of atleast 25 to 30 stocks to diversify company’s specific risk
