Zoom is showing a pre-earnings release run up out of its extreme low, ahead of its Q1 report today. The current run's pattern is indicative of professional traders swing trading with earnings strategies; they tend to take profits on the report since they bought at the low. While revenues are likely to come in below last quarter, earnings should improve over the big loss last quarter.
The stock has probably found its final low, at long-term support from 2020. ZM outperformed during the pandemic due to huge demand that was unsustainable and time limited. So it has a lot of work to do from here; it must reinvent to offer a greatly improved service to compete with huge companies like Google, etc. which all have very similar services.
