How we handle attribution

Famous investing quotes are misattributed more often than most people realise. A line gets repeated in a talk, then a blog post, then a thousand social posts, and the original speaker is quietly replaced by someone more famous. So we label rather than assume.

Sourced means we can point to a specific work: a book, a shareholder letter, a paper, an essay, or a recorded speech. Widely attributed means the line is consistently credited to that person but we could not identify an original source, so you should treat the wording as approximate. Quotes with a genuine attribution conflict are left out of this library entirely.

Quotes are kept short and are here for education and commentary. To read about the people behind them, browse the People directory.

Frequently asked questions

How do you know an investing quote is real?
We label each quote. "Sourced" means we can point to a specific work: a book, a shareholder letter, a paper, an essay, or a recorded speech, and that work is named on the card. "Widely attributed" means the line is consistently credited to that person but we could not identify an original source.
Why are some quotes marked as widely attributed?
Because honesty is more useful than false confidence. Many famous investing lines circulate for decades without anyone citing where they first appeared. Rather than drop them or pretend they are confirmed, we include them and say plainly that the original source is unidentified.
Do you include quotes that might be misattributed?
Quotes with a genuine attribution conflict are kept out of the browsable library entirely, and they are never featured. A well-known example is "the market can stay irrational longer than you can stay solvent", which is routinely credited to John Maynard Keynes but does not appear in his published writing.
Which quotes can appear as the quote of the day?
Only quotes that are sourced to a named work and that we are willing to show on their own, with nothing beside them to qualify them. Two separate checks: an unsourced or disputed line is never promoted, and neither is a line that needs an argument attached to be read correctly.
Why do some quotes carry a context note?
Because a quote can be perfectly real and still mislead on its own. Keynes writing that in the long run we are all dead was arguing about economic policy, not about holding periods. Carnegie telling you to put your eggs in one basket was describing a steel company he personally controlled in the 1890s. Those lines stay in the library and on their author's profile with a note explaining how to read them, and they are kept out of the daily and random picks.
Do you leave out quotes you disagree with?
No. Provocative and contrarian quotes stay, including ones that argue against how we would invest. What we do not do is put a quote on the homepage alone when it could be read as advice to concentrate, borrow, speculate, or treat someone else's failure as weakness. Those stay browsable, with the context that makes them worth reading.
Can I find quotes by a specific investor?
Yes. Use the person filter, or open any person from the People directory to jump straight to their quotes. Every quote links back to the person who said it.
