Ubiquiti Networks (NASDAQ: UBNT) stock can be volatile, as investors have experienced recently. The company’s founder and CEO, Robert Pera, owns almost 70% of the shares, and the remaining float is heavily shorted. That’s why even small hits or misses can lead to big moves. While the stock is still up 45% in the past year, investors had to weather a 25% plunge after last quarter’s earnings. The company reports again on May 4.
