  • Sir Isaac Newton makes the Investor's Business Daily
    Sir Issac Newton participated in the investment mania now known by historians as the South Sea Bubble, during 1720. On January 1, 1720, one share of South Sea Company stock was worth 128 pounds, on June 24, 1720, it traded for 1,050 pounds, and was shortly thereafter worthless. Newton is quoted as saying on the problem of knowing when to sell, "I can calculate the motions of heavenly bodies, but not the madness of people."
    In a much later response to this quotation, the legendary 20th century investor Warren Buffet writing in the Berkshire Hathaway annual report during 2006 wrote that Newton should perhaps have formulated a Fourth Law -- "For investors as a whole, returns decrease as motion (e.g., trading frequency) increases."
