Can anyone share how to find mutibagger shares

Market is at lifetime high, if we buy nifty share now risk is more than reward, for SIP no problem you can start here also, but lumsome entry friends can anyone share how to identify multi bagger shares in smallcap or Midcaps.

Whether it is SIP or Investment in Stocks directly, investing lump sum at once is not recommended

my own example. I bought Heromotoco 200 nos @ 4020. after that it went down to 3750 and 4100 and again 3920. if we buy small qty at regular intervals we will get better average.
