Dropbox's shares closed at $28.42 (roughly Rs. 1,840), up more than 35 percent in their first day of trading on Friday, as investors rushed to buy into the biggest technology initial public offering in more than a year even as the wider sector languished.
The stock opened at $29 on the Nasdaq and soared as much as 50 percent to a high of $31.60 in early trading. At the stock's opening price, Dropbox had a market valuation of $12.67 billion (roughly Rs. 82,200 crores), well above the $10 billion valuation it had in its last private funding round.
Its IPO priced at $21 per share late on Thursday, $1 above the projected range of $18 to $20, and was several times oversubscribed.
The solid first-day pop came despite weakness in the wider US stock market. The S&P 500 slid 1.8 percent while Nasdaq dropped 2.4 percent, adding to losses of more than 2 percent each on Thursday.
The S&P tech index was down 2.73 percent.
Dropbox's much-awaited debut ended a long dry spell in the US IPO market for big tech names.
The last so-called tech unicorn to hit the market was Snap last March, and the Snapchat owner is now trading roughly 4 percent below its $17 (roughly Rs. 1,100) IPO price.
"In the case of Dropbox, investors get a chance to get exposure to a next-generation tech company, which is a proven business model," said Tom Taulli, InvestorPlace.com analyst.
The pop in Dropbox's price may bode well for Spotify, valued at roughly $19 billion in the private market. The music streaming service has filed for a direct listing and will start trading on the New York Stock Exchange on April 3.
"Dropbox is going public at the right time. It has an attractive story to justify its need for financing and the market dynamics are good," said Josh Lerner, professor of investment banking at Harvard Business School.
"But at the same time, the environment is also competitive".
It has yet to turn a profit, which is common for startups that invest heavily in growth. As a public company Dropbox will be under pressure to quickly trim its losses.
The 11-year old company reported revenue of $1.11 billion in 2017, up from $844.8 million a year earlier. Its net loss nearly halved from $210.2 million in 2016.
"The strong performance of the Dropbox IPO may open the door for more technology unicorns to IPO throughout the rest of 2018," said Sohail Prasad, co-founder and co-chief executive of Equidate, a platform for trading of shares in private technology firms.
"If investors had bought Dropbox stock within the last six months, they'd be up over 75 percent."
