One IPO, two shares.

Investors Thursday pounced to buy shares of Zoom Video Communications, the firm that had its first public offering of stock.

But others might have mistakenly bought Zoom Technologies, a company whose stock was trading for under a cent in February and that their shares were delisted from the Nasdaq in 2014. Its total market value is significantly less than one-thousandth of the Zoom.

Stocks of Zoom Technologies — ticker symbol”ZOOM” versus”ZM” for the ballyhooed IPO — soared as much as 124.5% in Thursday morning trading. Enthusiasm for the stock came as the day went on — perhaps as more investors figured from the double Zooms — plus it ended the day up a modest 10.2%.

Zoom Technologies had a much bigger jump of 1,100 when its own IPO filed. Its shares closed at 6 cents.
