The relevance of the 200 day simple moving average (SMA) depends on whether or not a stock reacts to it. In the case of ADSK, the 200 day SMA is most certainly relevant. Just take a look at the chart. We highlighted all the times ADSK has reacted to the 200 day SMA with gray ovals. It has been testing the SMA from a resistance perspective quite a bit since early June. If it manages to break it in the coming weeks, there is likely a good bullish play there. For now, you have to stick with bearish until it breaks.
