The 30-Minute Stock Filter — Reject 95% of Bad Ideas Before They Bleed Cash

The average retail investor researches a stock for two hours before buying. They lose money anyway. Why?
Because they spent two hours on the wrong things. Reading press releases. Watching CNBC clips. Skimming Reddit threads. None of which protect you from a bad business.
The 30-Minute Stock Filter is the opposite. Five binary questions. If a company fails any one, you reject it and save yourself the next two hours — and the next two years of holding a loser.
WHAT YOU GET:
The five non-negotiable filters that Buffett, Fisher, Marks, and Klarman all use (in different language) — distilled into a single one-page PDF.
The exact data points to look up for each filter, and where to find them in 30 seconds.
The pass/fail decision rule for each criterion. No "it depends." Binary.
The post-filter action: if it passes, what to do next. If it fails, why moving on saves you money.
WHO THIS IS FOR: Anyone tired of buying based on tips, headlines, or vibes. Beginners who want a single repeatable filter to start with. Intermediate investors building a quality screen.
WHO THIS IS NOT FOR: Day-traders. Momentum chasers. People who like complexity for complexity's sake.
FORMAT: One-page printable PDF. Stick it next to your screen. Use it before every buy.
