Charles Munger, Berkshire Hathaway co-founder and Warren Buffett's longtime partner, advocated investing only in businesses one understands. His three-basket approach categorizes investments as yes, no, or too difficult to comprehend. Munger emphasized understanding business mechanics, intrinsic value, management quality, and fair pricing before investing.
