Sigh....no, that's completely wrong. TSLA was simply their highest conviction stock and therefore their largest holding. The fact that it has been one of the best performing stocks has certainly supercharged the performance of ARK funds that hold TSLA but ARK's performance is impressive even if you back their best performer and largest holding out of the equation.
That's so wrong I don't know where to begin. You can't blame TSLA for bubbles in the stocks of other EV companies. This is the result of investors becoming aware that EV's really are viable and they are the future. If investors bid undeserving companies higher than they deserve then the fault lies squarely on the shoulders of those investors over-bidding. And it doesn't harm those who are not over-bidding. In fact, it can help them if they owned those companies before they were bid up. All they have to do is sell for a nice profit.
I don't see the supposed problem here. So a stock got bid up too high and fell back down (according to you). So what? It happens all the time. Investors did this, not Tesla, not ARK. Why do you blame innocent bystanders who are doing what they should be doing?
Again, don't blame Tesla for this simply because they are performing skillfully, blame investors. But this kind of thing happens all the time and I don't see the problem.
Of course ARK's valuation of TSLA is speculative- that's the number one job of investors- to be speculators! That's how investing works (through speculating). I shouldn't even be wasting my time addressing such ridiculous assertions.
I'm stunned that you think an investor should do anything else other than speculate.
And quit blaming Tesla and Cathie Wood for doing their job when the things you are worried about are 100% due to other investor's actions. If there is blame, put it on the people responsible. And it's not even clear why you are concerned- investors have a long history of bidding some stocks far beyond any rational hope - it all gets taken care of in the end.
