At the moment, near-term support sits somewhere around 2320 (price support) to 2338 (external Fibonacci support shown in yesterday's chart).
A drop and hold below 2320 could see a swift plunge to 2250, or lower and may be influenced by a major change in market perception of Washington's ability (or inability) to function and produce any meaningful progress on the kinds of economic stimulus programs, tax cuts and reforms, etc., as promised by politicians during last year's election and, on which, market players were counting, as they invested heavily from that time...particularly, as the Fed reduces its monetary stimulus measures and continues raising interest rates.
We'll see where any political facts (if they surface), relating to ongoing investigations, lead the markets. No doubt any major shift in overall market confidence (to the downside) would produce such facts and resolutions sooner rather than later, inasmuch as 3 Trillion dollars added since the election remains at stake, as I've described here and here.
