IPOs

What is Lock-in period?

Hinglish mein padhein: Lock-in period kya hota hai?

A lock-in period is a time during which certain shareholders — promoters, anchors or pre-IPO investors — cannot sell their shares.

When large lock-ins expire, the supply of shares available for sale rises, which can pressure the price.

Lock-in expiries are disclosed in the prospectus.
