TSLA is a cult stock with unbelievable momentum. I do not regret in the least that I never jumped on that train, because it would have violated every rule of discipline that I have tried to follow. I am too old to take anything but very small gambles on what I see as pure momentum plays, because they can reverse at anytime. If I was a young man, I probably would have bought in, but I'm not and have to follow the disciplines I have set for myself. I still take long shot chances with smaller investments, but ones where I can see the "if this, this and this....then that" scenario for the company, not just momentum. Other than pure momentum from its cult following, I've never found a reason to invest in Tesla. Not yet, anyway; but I do consider it from time to time.
