IPO Lockup Expiration

While doing my research on IPO stocks i always come across lockup expirations.
For example, I am studying:
PGNY, PING, NEW and DDOG have lock up expirations.

PGNY had an IPO base breakout on Friday
DDOG and PING have retreated to their IPO price and have large number of shares being released into the market.

Could you please comment on how to handle these situations as it becomes quite confusing to understand the impact on stocks.
