Despite a government shutdown in early 2019, the IPO market has been fairly strong. Early signs indicate that 2019 could come close to a record last set in 2000, when $97 billion was raised in the dot-com bubble. This year, IPO research firm Renaissance Capital projects the IPO market may raise more than $100 billion. But Uber Technologies’s IPO put a pall on everything, with story after story hashing out the details as to why the company’s stock price tanked after its IPO. Investors like to see profits or a clear path to profitability, and not all the household names in tech can show that. Zoom Video Communications, on the other hand, had a completely different reception. The tech company provides video conferencing software, including up to 40 minutes free, and posted an adjusted net income of $5.7 million in the fourth quarter of 2018, on revenue of $105.8 million. It was rewarded for its focus on the bottom line. In fact, its share price rose 120 percent by early May— in less than a month after its IPO—making it the best-performing public offering of the year among offerings raising at least $300 million. The soaring price is leading investors to speculate the stock is hugely overvalued.

But Zoom definitely has characteristics that win over customers, including a good product. It also is wooing investors with substantial growth in the last few years.
