Investors make the mistake of getting so acclimated to super rich valuations for 10+ years straight in 90%+ of stocks, that they forget what value looks like.
Buying something that's growing 5-10% at 20x FCF is not a value opportunity just because it's down 20% from it's ATH.
Value is not subjective, it is objective.
The more you study opportunities from history (even recent history, in the case of $META 2022), the less FOMO you'll feel to buy trendy stocks just because they've fallen 20% (from like 25x FCF to 20 FCF).
\[obligatory edge case disclaimer when you believe a company will sustain 20%+ growth for several years, and therefore you believe 15x\~ FCF is indeed value\]
