There's only one indicator here: the 200-day moving average on the S&P 500.
For the first time in almost ten years, this level has been breached to the downside. We are officially in a bear market, and there could be much farther to fall.
Today's close will be a historic one, as the Fed pumping over a trillion dollars worth of liquidity into the markets didn't seem to do much of anything at all, with markets STILL sinking by about 8% across the board.
