Why might the VIX be moving up along with the SPY? Nobody can say for sure, but as traders we need to see these patterns, factor them into our analysis, and be ready for whatever may lie ahead. I hope these two little charts are both helpful and useful to you in your analysis.
Always measure your risk and be okay with being wrong ; ) Wait patiently and get the price that you want. Use the market. Don't let the market use you.
