The S&P 500 Index has also broken through key support at 1330. It is doesn't rebound by the end of the day, or if it goes substantially lower, prices will likely go much lower still in the near future. We may test the lows of last Spring.
The NASDAQ too is plunging, but without support levels, it goes down even faster!
This could spell much lower stock prices to come. It remains to be seen if stocks can rally to take the stock indexes back above key technical support levels, but by just looking at these charts, the probability doesn't look that good.
