V1Value

Margin of safety

Buy at a meaningful discount to intrinsic value. The discount, not the forecast, is what protects you when you're wrong.

— Benjamin Graham, The Intelligent Investor (1949)

V2Value

Mr. Market is bipolar

The market is a moody business partner who quotes a price every day. Use his moods; do not be guided by them.

— Benjamin Graham, The Intelligent Investor

V3Value

Buy a business, not a ticker

Treat every purchase as buying part of a real company. If you wouldn't own the whole thing for 10 years, don't own a slice for 10 minutes.

— Warren Buffett, Berkshire shareholder letters

V4Value

Circle of competence

"Risk comes from not knowing what you're doing." Stay inside the boundary of what you can value confidently. Pass on the rest.

— Warren Buffett

V5Value

Great business at fair price > fair business at great price

Quality compounds. A wonderful company bought at a reasonable multiple beats a mediocre one bought cheap, almost every time.

— Charlie Munger, Poor Charlie's Almanack

V6Value

Scuttlebutt — talk to customers, suppliers, ex-employees

Financial statements describe the past. Conversations with people around the business describe the future.

— Philip Fisher, Common Stocks and Uncommon Profits (1958)

B1Behavioral

Losses hurt ~2× more than gains feel good

Loss aversion makes you sell winners too early and ride losers too long. Notice the asymmetry before you act.

— Daniel Kahneman, Thinking Fast and Slow

B2Behavioral

Know what you own and why

If you can't explain the thesis in 2 minutes with a crayon, you don't own it — you're holding it.

— Peter Lynch, One Up on Wall Street

B3Behavioral

Invert, always invert

Ask how to fail first, then avoid those things. Most investment success is from not making mistakes, not from genius.

— Charlie Munger
