Tesla is rallying for a sixth day, with shares up another premarket to over $800, following yesterday's incredible run that saw the stock skyrocket 20%. The latest? Panasonic said its business turned profitable in Q4 as Tesla's battery output helped push that division into the black, while Argus and Ark Invest issued some bullish predictions. TSLA has now climbed 79% in just 2020 alone, and has tripled in value since Q3 results were reported in October.
