Oh sure, when he is not arguing with shorts, he is doing good PR work for Tesla on Twitter.
You ask why he has an impact on the stock at all? Mostly psychology I guess. People think that Tesla needs Musk, I disagree, but if he behaves reckless, he seems unstable and risks having to step down.
And why does Tesla need a high stock price? 9 billion in debt.
First about Tesla&Musk.
His tweets about shorts shouldn't hurt SP. There is no explainable mechanism which would describe why investors should be scared or repulsed by such tweets. As well there is no objective reason not to react on positive tweets addressing very important improvements in V9, or sell procedures. But it happens.
Tesla's debt is while serious thing is nothing exceptional and they have enough of instruments to refinance even if they would run out of cash. Only autopilot thing i enough to cover all debt.
The thing is they won't because Model 3 is designed in it's basis to be profitable.
Tesla makes autos in the way it makes because of Musk, putting GM executives will make from Tesla GM.
If you want that probably you should just invest in GM.
Now about stock trading.
there is no "psychology" involved in the way they claim.
GS moves stock by making provocative jumps an downs. Others are less aggressive and hijack existing trends (initially by monitoring them and amplifying when detected). It is boring bone headed if to use Musk words mathematics, and no it has nothing to do with "quantum" or other sh^t.
The only piece of "psychology" used is old known banality coming from ethology.
"Sheep follow goats". Lazy shepherds use goats to guide and control flock. Unlike dogs goats eat grass and don't require shepherds approval or every minutes guidance. You have big banks= "goats" and there are "sheep"=you.
You follow the stock trend because it is the rule you are told to follow.
People who were conservative with selling their stock during 2008 crash, lost much less than "weak hands"(people I know lost nothing). People who have bought SP from the "weak hands" earned big money.
long investment is about people and fundamentals. Short trading is speculation, and is essentially gambling. Current system in it's financial base is short term Ponzy Scheme, where people in the first tides collect cream, and the last dust.
Small reminder.
