Such reactions do concern me. Perhaps the largest single risk with TSLA is the ancillary impacts of volatility. High volatility tied to a 'story stock' accentuates the risk. People who have temporary success, often for extended periods of multiple years, grow to have high confidence in their laity to understand how to capitalize on MMD, triple witching hours and all the myriad technical 'measures of merit'. When one hugely successful person is prominent many of us forget about Tony de Angelis, Bernie Madoff, Long Term Capital Management, Deutsche Bank, AIG and all the others. That invariably ends out poorly, sometime... even though precise timing tends to be difficult or even impossible.
With Tesla (and SpaceX) we have a genuine defining moment which has gigantic potential. Others that did similar things in industrial terms included McCormick, Ford, Edison, Westinghouse but also Xerox, Kodak and what ended out as Penn Central. All those are just a handful of US examples.
Stories fit right in with all of these, just as they do with Tesla. Oddly, perhaps, all of them also went through periods of high volatility that made and lost fortunes.
The ones who lost rarely did so without taking margin loans and pursuing 'technical' approaches. Or course a few of us keep pointing out this risks and

even shared family history.
While in graduate school I studied under one of those Nobel Prize winners. I even had a seminar from the FOMC secretary when Nixon dropped the ax that helped initiate the 1973 oil crisis. Luckily for me I made my losses almost instantly so they were both small and no permanent blots. To my chagrin when observing the beginnings of the 2008 events I could not convince my then largest client not to buy a huge mortgage originator (option ARM, anybody?) and a famous name investment bank. Luckily for them The ever handy Secretary fo the Treasury and his cohorts fount how to bail them all out. The personal investors were largely annihilated.
Now many of us are giddy with our recent speculative successes. The most technically oriented among us should know that the only people with a true stop-loss are the market makers, for they own the casino. The best individual talent will end out ruing the day. Why? Listen to all of you. Some is good, more is better, only too much is enough. If that colloquialism is too inadequate then ask yourself if you know what the 'boundary conditions' are for your most trusted quantitative techniques. 'boundary conditions' are those distressing results you'll find out about when the future departs the path of the recent past.
Unpredicted earthquakes, floods and fires happen. Supply chain disruptions happen. Accidental death happens. Every one of those can and does trigger departure from historical patterns. Of course I have not mentioned political and regulatory risks. That is the part of history that the vast majority of investors totally ignore. After all it is boring to talk of AT&T, Standard Oil, and so many others. It's much more fun to imagine that Tesla will end out dominating the world vehicular and energy markets.
I am a Tesla bull. I also ensure that no single investment choice can act to destroy my well-being. Foolish advisors do not understand what diversification actually means because they cannot understand how to hedge risk. Their hedges often increase risk rather than reducing it.
