Putin using tactical (not strategic) nukes is a real possibility, and one that hasn't been priced in the market. Without a doubt the DJIA would fall another 1000pts+ the day(s) that happens. Not just because of the act itself, but because of what the retaliation from the west would be and what that could spiral into. There are a number of reasons the mid term rally may not occur, which worries me.
There are some on here who say they dont trade news/fundamentals, but rather just the chart in front of them. To me, thats like a surfer saying he doesn't care about the waves and only focuses on the board he's on...
