The market quotes a price every day. Value is a separate question, answered by the business rather than the quote.
Start from an observation you can make and others cannot, then do the work to see whether the market already knows.
Stock idea generation and the stock pitch question in any buy-side interview.
From One Up on Wall Street · Peter Lynch
State the liquidity first, because the argument that prices overshoot value is only available to those who can wait.
Any crisis communication, any question about buying in a crash, and infrastructure or real asset valuation.
From Bruce Flatt's March 2020 update to Brookfield shareholders · Bruce Flatt
The price of risk tracks the mood, so the useful time to buy is when the mood is worst, and the dangerous time is when it is best.
Any question about market timing, contrarian investing or what to do in a crisis.
From Berkshire Hathaway's 2008 letter to shareholders · Warren Buffett
Decide what a business is worth before looking at the price, then act only when the price is far enough below.
Any stock pitch, any conversation about whether a market move is a reason to act, and any valuation that starts from the price.
From The Intelligent Investor · Benjamin Graham
