I can't get too excited about possible market follow-through in any one direction on the S&P 500 Index unless and until price breaks and holds either above 150 or below 100 on the SPX:VIX Daily ratio chart below.
Currently, price is still in what I call the "Major Conflict Zone." Yes, I realize it's a huge range, but that's the way 2015 has gone. In my opinion, I think 2016 will see greater volatility and much larger swings than we've seen this year...hang onto your (Santa) hats, folks!
