When the market start to have more brands and models appearing, sure the market shares will decline. Importantly, Tesla is still making profit. Also Tesla not only depends on EV cars sales, they have charging station and services render and others services to make profit from. Should see the overall financial status rather then only EV cars sales to see their overall performances and their piggy bank balances to determine. How can a company that wasn't making as much as before that their share value is lower than the beginning when the company first started. Think the comments are just to push down the prices and then buy the shares and comments other goodies so they can make a profit and the circle goes over and over again. So if you have a weak hand and don't have extra cash don't touch the counter. These kind of situation happened to Amazon, FB, Apples and afew others before. See what happened to all these counters today. So don't get trick by comments, do your own DD.
