$Zoom(ZM)$Oversold.. panic selling after earning reports.. With the μ-variant and perhaps more variants to come, Zoom will still be in high demand. It’ll eventually be a norm for many businesses/organisations.

Stay true to the stock if it's a good stock to hold onto. Never buy on greed and sell on fear. Don't let emotions take over. Mixing fundamental and technical analysis to find your own sweet spots when buying/selling gives a good balance.

Shorter timeframe, confluence of signals. Use fibonacci analysis, support/resistance and strickly buy on uptrend. Harder to make profit on downtrend than uptrend.
