Isaac Newton was a genius, but even he lost millions in the stock market
But there's a big difference between being a smart physicist and smart investor.And, unfortunately for him, Newton learned that the hard way.
"Back in the spring of 1720, Sir Isaac Newton owned shares in the South Sea Company, the hottest stock in England. Sensing that the market was getting out of hand, the great physicist muttered that he 'could calculate the motions of the heavenly bodies, but not the madness of the people.' Newton dumped his South Sea shares, pocketing a 100% profit totaling £7,000. But just months later, swept up in the wild enthusiasm of the market, Newton jumped back in at a much higher price - and lost £20,000 (or more than $3 million in [2002-2003's] money. For the rest of his life, he forbade anyone to speak the words 'South Sea' in his presence."Here's a look at how South Seas moved back then.
Or as Graham described it: "For indeed, the investor's chief problem - and even his worst enemy - is likely to be himself."
