Meta Platforms, Inc.
Thesis
Facebook fits the investment framework of a 'compounder' due to its strong network effects on both the supply (users) and demand (advertisers) sides. With a total addressable market for advertising exceeding $500 billion globally, Facebook has significant room for growth despite currently holding a low single-digit share of revenue.
Did it work?
inconclusive
confidence: low
The pitch is a long-term structural thesis (a 'compounder' with network effects and a large TAM) with no stated price target or horizon, and no price performance data is provided. Without either a return figure or evidence that the thesis's specific claims (user/advertiser growth, share of the $500B ad market) have played out or been invalidated, there is nothing to judge the outcome against.
