As a rule of thumb it is never priced in when a company suddenly has tremendous acceleration in revenue and profit growth. Wall Street is good at forecasting businesses with a stable growth trajectory. Wall Street is way too conservative at inflection points because it’s too embarrassing to be wrong (in either direction).
Meme stocks are always priced in as well, since the investor speculation far outweighs any effects from irrelevant things such as how the company is actually doing in real life.
