On SeekingAlpha I came across of quite interesting article, where author discuss a stock manipulation caused by social media. Sudden rise of share price driven by Robintrack, which is a tracking a popularity of certain stock across Robinhood investors, who do not invest on fundamentals but on popularity and are able to move not only microcaps but probably also companies like TSLA.

The article is here https://seekingalpha.com/article/4351970-bubble-bubble-toil-and-trouble. Bellow I am also attaching the LAC chart on Robintrack https://robintrack.net/symbol/LAC, IMHO it may explain recent shareprice sprint.
