I had to talk myself off the ledge from selling a chunk this morning at $845. The "best investors are dead" ran through my mind and I shut my laptop and went back to fixing electrical things (mostly light fixtures) at the hospital I work at. Now that my investments have reached this level I feel like I should lock in my gains and never worry about money again. This is so distracting. Can someone talk me off the ledge again?
One of my siblings bought TSLA in part because I’ve been so bullish. He had at times, though no longer, asked if he should sell. I told him my four questions for deciding when to sell an investment. If any response is a "yes," then sell (or don’t buy in the first place):
1) Do you consider any of the company’s products, leadership or actions morally deficient? I drink wine, but would not own a winery as I would not like to be part of selling an addictive substance for example.
2) Do you need the money and have no alternative than to sell?
3) Has your investment thesis changed? For example, you don’t believe the company will execute as well as you had thought.
4) Have you found a better investment factoring in capital gains taxes and whatnot?
3 & 4 are interrelated. There are myriad considerations, for example regulations, too. The various considerations might be bundled in different ways into different questions.
For me, these four questions suffice. YMMV, not advice.
