What is so significant about YTD?
You can arrange the data in any number of ways to tell a story: A Tesla investment since 2014 has lost money (and been diluted). Go back to 2013 and suddenly it's a goldmine.
Tesla having been a "good purchase" depends on what you paid. But I have a feeling that more people are sitting on a cost basis >$250 than <$100, in which case a TSLA investment has been mediocre.
