I can understood in perspective valuation which too much high for ZM stock. But in reality, stock price depends on buying & selling pressure.
Elliot Wave theory, has 5 impulse waves to upside/downside depends on the price action. In ZM stock, 4 waves have been completed and last wave which is Wave 5 is in action now. Wave 5 is divided into 5 sub waves again where we are sub Wave 3 right now.
Currently in cup & handle pattern. Also check RSI, Stochastic RSI & MACD.
