Electric automaker Tesla proved the short sellers wrong this year and welcomed a flood of retail investors cashing in on the stock's huge rally in 2020, according to Credit Suisse. 

The Wall Street firm — which has a neutral rating on Tesla — said the many investors that shorted Tesla's stock have been burned, only to be outsmarted by the individual investors that appreciate Elon Musk's vision for the car company.
