It's the weekend, I guess a little bit OT is ok.
I feel investment and trading are not trivial tasks. To do well we need a lot of knowledge, experience, discipline, rational thinking...
Planning is also an important step. Plan for your daily exercise. Health first.
Plan ahead what you would do for each situation. For example, I plan to increase 2.5% if the stock drops to xyz level if no major reason, or cut loss for trading shares at xyz level. Write down the plan, act accordingly, and revisit what you did right or wrong.
Plan the upper limit for each holding, respect your plan unless you can write a valid reason to change the plan.
Surprise can happen. I never thought TSLA could drop this much while the stock market is so strong, while nothing major happened. Luckily my plan has been keep saving cash, wait for big drops then buy more. So far I have been acting according to my plan, so I don't feel too bad seeing the drop. While my plan is to keep adding after big drops, that doesn't mean I keep adding blindly. At certain level I have to stop and check if my thesis is wrong.
If TSLA goes significantly lower from the current level, a lot of share holders will get hurt permanently, many will be forced to sell. I hope Tesla quickly find one or a few strategic partners, There are a few candidates we discussed in the past: Google, Apple, Microsoft, Amazon, Softbank, Tencent, Alibaba, Oracle, Larry Ellison, Bill Gates, Larry Page, Sergey Brin, Jeffrey Bezos.... If this partnership can help Tesla grow strong and faster, it may be worth it. Tesla can always buy back shares from the market in later years when they get boat load of cash.
If one of the above parties buy 10% from the market, then Tesla issues another 10 new shares to this partner, the situation will be quite different.
Or if Tesla can find three of the above each buy 10% from the market, then Tesla issues another 3% to each of them...
