Are Electric Vehicle Stocks in ASEAN Countries Investible during the Covid-19 Pandemic?

Abstract Electric vehicle, as one of the low carbon footprints, has transformed a wide range of energy and public sectors. Utilizing the WHO Covid-19 pandemic statement, we search for the optimal portfolio from the top seven Electric Vehicle (EV) enterprises in ASEAN. Using the MonteCarlo simulation of optimal risky assets portfolio, we find that before and during the pandemic, the optimal portfolio weights differ significantly. Before (during) the pandemic, the investment weight of optimal portfolio consists of Toyota Motor Corporation 49.83% (42.99%), Star 8 Corporation 23.20% (9.73%), Hyundai Motor Corporation 20.81% (10.63%), BMW.DE 2.79% (32.08%), Honda Motor Company 2.56% (0.64%), Mitsubishi Motor Corporation 0.68% (0.09%), and Nissan Motor Co. 0.14% (3.84%). The Sharpe Ratio shows how during the pandemic, the portfolio of EV stocks give more excessive return compare to their risks, from 93.55% to 250.62%. These findings support the notion of how EV stocks are investible, especially during the Covid-19 pandemic.
