Buffett's $1 billion investment in Coke seemed insane at the time — here's the framework behind his most profitable contrarian bets.

Buffett's greatest successes share three traits:
His worst bets — airlines, textiles — lacked these qualities. The lesson: quality compounds, cheapness mean-reverts.
Based on his framework, Buffett would likely focus on:
He'd avoid most tech except dominant platforms like AAPL.
