Should I double buy some?

Curious, how do you evaluate any stock (whether a penny or a popular one)

I have one ATRenew (RERE) and have been at PE of 27 despite having a gross profit margin of 20.7% which ranks in the 38.0% percentile for the Sector. Rere in 1 Year Price Total Return of 78.5% ranks in the 91.2% percentile for the Sector also.

While I love the company and have been holding for a while and I can justify that the price now is sensible. (remains near the stock’s recent range and above the midpoint of its 52-week trading band, around $5.3 - $5.4)

Would love to understand how you are evaluating it abt your investments more.
