Just review Zoom$Zoom(ZM)$ company history :
1. Zoom's research and development costs are 10 percent of its total revenue and less than half of the median percentage among its peers.
2. It is amazed how fast and stable this company can grow
3. It is good when it could not buy Five9 with proposed price 14.7 billion
They have tons of cash like 5 billion to invest more for R&D next year. Wow
