MSFT is recovering from a huge drop a few weeks ago. It has formed a higher low, and now we need to see a higher high (check the right shoulder of the H&S pattern). If we see a higher high, we can safely say that we have a continuation of the uptrend, with a likely target of an all-time high (ATH).
However, if MSFT drops and falls below the neckline, it could be the end for MSFT for years. MSFT has formed a huge H&S pattern with a neckline around 400. So, there are several significant support levels: the round number 400, the neckline, and the trendline from 2022. If MSFT drops below these, it could be disastrous.
