The frameworks

You can't apprentice under them.
So we bring their frameworks to you.

Proven frameworks, each drawn from the published writings of the investor who mastered it and matched to the businesses it explains best. Four are ready to use today — and the library keeps growing.

“Price is what you pay. Value is what you get.”
Warren Buffett
Consumer franchises
Framework drawn from his shareholder letters, 1977–2024.
How Buffett reasons
  • Durable moat & pricing power
  • Honest capital allocation
  • A fair price, margin of safety
“You can't predict. You can prepare.”
Howard Marks
Cyclicals
Framework drawn from his memos and The Most Important Thing.
How Marks reasons
  • Where we are in the cycle
  • Downside first
  • Survival under stress
“Know what you own, and why you own it.”
Peter Lynch
Consumer & retail growth
Framework drawn from One Up on Wall Street.
How Lynch reasons
  • Growth you can understand
  • A reasonable price (PEG)
  • Store & category runway
“I want a few outstanding ones.”
Philip Fisher
Quality growth & tech
Framework drawn from Common Stocks and Uncommon Profits.
How Fisher reasons
  • R&D & management strength
  • A long runway
  • A few outstanding compounders
The library keeps growing
These four are ready to use today. We keep studying the great investors and add new frameworks over time — each matched to the kinds of businesses it explains best.
