If you go long at 5 and the stock goes to 0.5, that's a 0.9 loss, not 0.95 You naughty theoretical physicist, you!
What if the stock moves in a rather narrow channel, let's say 90-110? Then both the risk and the payoff are very similar, long or short... Also, sometimes the whole market is falling, and you might as well trade it instead of just being in cash....
oops, must be couple of bottles too many. these Russian physicists influenced me the wrong way but anyway, it is still peanuts 0.9 or 0.95.
Didn't Musk also go on CNBC about a month ago basically saying TSLA is overvalued now? Something to the effect of 'the market is being very generous with our valuation.' Didn't watch it, just heard it happened.
Tesla or not, the new trend soon will be a big rise in alternative energy sources. Solar, Wind are already here and they will be made more efficient and thus cheaper. Expect many more new sources to chip in also
