Analysts' consensus revenue and earnings estimates are pretty much in line with what Zoom's management is expecting in the fourth quarter. Wall Street estimates that revenue will be $811 million and non-GAAP diluted earnings will be $0.79 per share. 

Zoom's quarterly results have consistently beaten the Street's estimates recently, so investors are likely optimistic that the company will do so again in the fourth quarter. 

Now what 

The video communications company has been a favored tech stock among investors and is up more than 277% over the past 12 months. But the company's share price is down 17% over the past three months as investors have grown concerned that COVID-19 vaccines and the slow return to normalcy in some countries could curb Zoom's growth.
