What you learn: When to sell your stocks
From: @borrowed_ideas, founder at
Even after investing for 14 years, I uncover new insights every time I reread his letters.
Recently, I reread his letters from 1977 to 2020 for a third time.
Here are my key insights:

1. Moat is NEVER stagnant
A company's competitive position either grows stronger or weaker each day.
Widening the moat must always take precedence over short-term targets.

2. Commodity businesses
A business without moat will have its returns competed away.
Regardless of improvement, your competitors will quickly copy your advantage away.
Where returns on capital is dismal, reinvestment will only destroy value.

3. The flywheel effect
Buffett was preaching about the flywheel effect before it became cool.
Back then, newspapers were similar to today's platform businesses like Amazon, Meta, and App Store.
More readers beget more advertisers beget more readers.

4. Operating leverage
Companies with high fixed costs and low variable costs will see earnings rise faster than revenue.
However, it cuts both ways.
It becomes a disaster when revenue is declining.
