Vix (blue line), Vix 400 EMA (white line) and S&P500 (green line). I chose the 400 EMA, so we can have a better and cleaner trend perception. An uptrend in the Vix 400 EMA (red arrows) could lead to major crashes or corrections (red circles). Observe that the EMA showed a small downtrend during 2021, but since the end of the same year it recovered the uptrend (see the last red arrow) due to the recent correction. Nevertheless, since 2018 and, in a more perceptible way, since the Covid crash, the Vix is in an uptrend. It's an indicator to pay attention in the following weeks or months. For now, we could say that the tension seems to be rising.
