Is This A Minor Correction Or Something Worse?

The fact that the Fed telegraphed its decision to begin tapering QE later this year, assuming that the current trajectory of economic data holds, was not an enormous surprise to me. However, the combination of the Fed decision, bad China data overnight and a liquidity squeeze in China have served to exacerbate the global market selloffs as I write these words.

Is this just a minor correction or the start of something worse? These are some technical lines in the sand that I am watching. First of all, the decline in the SPX has been contained at its 50-day moving average in the recent past. Can support at the 50 dma, which is at about 1618 hold?
