I'm talking about the last few weeks. In the last few weeks, it's gone down by about 19%. A huge drop. I bought BYD stocks because how everyone was singing about BYD's sales were skyrocketing across the globe and how it was beating Tesla left and right. AND Buffet also invested lots of money in BYD. And then BYD stock went down by 19% since I invested a few weeks ago. WHY?
