April 20th : Isaac Newton made a +100% profit on this day, almost 300 years ago

Dear readers and finance enthusiasts,

on this day (April 20th), but in 1720, Sir Isaac Newton decided he could no longer bear the frenzy of the markets around the South Sea Company shares (first IPO in England), and decided to sell them, thus making a whopping +100% profit in the operation! Alas, and this is a reminder that past performance is not a guide for future performance, Sir Isaac Newton would then enter the game again, and lose much much more in the end… More info here, and on Wikipedia and thanks to Jason Zweig (WSJ) for bringing this to our attention today.
