Use a checklist covering moat, management, unit economics, and capital allocation; track long-term cash generation instead of quarter-to-quarter noise.

Ignoring management quality and capital allocation
📚 Case Studies

John Bogle Launches Vanguard Amid a Brutal Bear Market (1974)
In 1974–1975, during one of the worst post‑war bear markets, John Bogle founded Vanguard and prepared the first index fund. Stocks had fallen ~45% from the 1973 peak. Many investors fled equities and shifted to cash and “hot” active managers, doubting the wisdom of broad, low‑cost indexing.
✨ Outcome：Those who stayed invested in diversified U.S. stocks saw strong returns through the late 1970s and 1980s. The S&P 500 compounded dramatically, validating Bogle’s view that disciplined, long‑term ownership of the market beats short‑term trading and panic selling.

Staying Invested Through the Global Financial Crisis (2008)
In 2008–2009, the S&P 500 fell over 50% from its 2007 high. Terrified investors sold en masse, many abandoning stock funds near the bottom in early 2009. Bogle publicly urged investors to hold their diversified index funds and avoid trying to time the rebound.
✨ Outcome：From the March 2009 low through the next decade, the S&P 500 returned several hundred percent. Investors who stayed the course fully participated in the recovery, while those who sold often re‑entered late, locking in losses and missing substantial gains.
