The thing to keep in mind, regardless of opinions and funnymentals, a stock trading near or close to all time highs (yup even ones fueled by the fed) have no, nada, zip, zero overhead resistance. No one has bought above the split adjusted ATH of $502.49. So naturally no one is sitting there waiting to possibly bail out. If this level holds more shorts or profit taking make occur putting pressure to move lower. But if the level gives way, like Chumpie talking to his puppetmaster Putin, $600, $700 who knows how much higher it might go till reality sets back in?
Picking tops is a very, very low probability trade, for the simple reason that there are dozens and dozens of possible "tops" during an uptrend, but only one (1) REAL top (and vice versa for bottoms). It is, indeed, a very lousy bet, from a strictly mathematical perspective! That is why the overwhelming majority of traders lose their money playing that losing and highly costly "pick the top/bottom" game. There is also a psychological element in play : traders love to brag and say something like "I predicted the top of that market days ago", at cocktail parties or at their favorite local bar. By contrast, saying "I make my money following the trend" is not sexy at all, for most people (seriously, try to pick up ladies with that line).
I suggest you look at the various videos (at least the ones I posted) on the Tesla 2020 thread for answers to your question, then come back and ask more questions if you'd like. But comparing Tesla to other car manufacturers is your first misconception.
Absolutely. In fact using fundamentals as a timing device is ALWAYS a mistake, at least in the short term. The Trading Cemetery is filled with traders who believed the market was "overbought" because blah blah blah blah....
That and the adrenalin rush from keeping your finger on the buy/sell key when your stock is moving in your guessed direction, letting it go until the click. If the trend switches right after, you're king of the world in your head. If the trend keeps going, the adrenalin rush turns into instant disappointment, a woulda coulda shoulda moment. And the cycle begins again.
