No. The stock won't go up much if it all. Might go down. For the semi, Tesla did not talk about partners or customers, and building the thing will be considered impossible without a capital raise. It's all just a speculative press release. For the Roadster, 2020 is far away, it's a rich guy's toy, and we're looking at more distractions from actually manufacturing the Model 3. Nothing here for shareholders.
Meanwhile, here in Tesla lust land, if I can find an order button for that Roadster I'm on it! I bet they're sold out of founder models right quick. Hardcore smackdown indeed! Sports car and drag strip fans can all hang their heads in shame over the crap they've been satisfied with since forever.
