Shares of Zoom Video Communications soared more than 72 percent in the company’s trading debut last week, capping a roughly 1,700 percent rise in its value over the past two-plus years.

Yet it wasn’t even the best performing stock named Zoom in the past month. Since late March, shares in Zoom Technologies, a so-called penny stock whose ticker symbol is “ZOOM,” have jumped nearly 27,000 percent.

On March 21, a share of Zoom Technologies traded at less than a penny, although none traded hands that day, according to FactSet. The next day, Zoom Video filed paperwork for an initial public offering, and Zoom Technologies shares rose to 6 cents. The stock hit a high last Monday of $5.76 and finished Thursday at $2.70 with nearly one million shares trading hands.
