On November 15, 2019, the S&P-500 reached 3120 for the first time ever. For the next 63 trading days, the S&P continued relentlessly higher, topping on Feb 19 at 3393. Just four days later, the S&P was back down to 3120, almost instantly erasing three full months of gains! Nobody could have seen that coming ahead of time, could they? We know of at least one person who did.
