Traders are increasingly betting against struggling electric vehicle maker Nikola . FactSet data showed short interest in Nikola increased by 12% to 97.4 million shares. That represents more than 35% of the shares available for trading. Nikola shares have taken a beating in 2022, losing roughly 67%. The stock has also fallen about 96% since hitting a closing high of $79.73 on June 9, 2020. To be sure, BTIG's Gregory Lewis thinks the stock can bounce from current levels. The analyst last month upgraded Nikola to buy from neutral and slapped a $12 price target. "We believe NKLA is well positioned to benefit from increasing demand to decarbonize the Class 8 truck market. NKLA plans to roll out its FCEV (fuel cell electric vehicle) next year and continues to develop its H2 fueling infrastructure network in North America (currently has no stations)," Lewis said.
