That's when market sentiments, the "consensus" HAPPEN to agree with the fundies. If the market, the maaaaarket as my prof. used to say decides the other way, the fundies will still go out of the door. And the only reason why RH's share price is more reflective of its fund. analysis is because there is not a lot of big following, big "consensus" putting their own spin on what the company is really worth.
The fund. analysis does materialize in the long run yes, don't get me wrong. If the company is really crap, people or the maaaaarket will eventually realize it's crap regardless how much hype you can build upon it and the PA will eventually reflect it. But in the short run, that's not the case and by the time the real fundamental analysis of a company materializes, it might already too late. As John Maynard Keynes would say in his most famous quote, "in the long run, we are all dead". The idiot argued against the Gold Standard and look at the mess that we are in now.
Well... yeah. I mean to a great extent you're right. Look at TSLA. All hype imo compared to the stock price. Ford has a PE around 8. And where would NFLX be without hype? Good company I suppose, but it certainly doesn't justify a PE of 150 or whatever it is now. Your professor needed to discuss the short interest too. That certainly plays in.
So yes, as a swing or day-trader, fundy's matter not. (earnings events aside) But in the long run, water always seeks its level and companies eventually become fairly valued. Long or short. PE and PEG are still by far the most widely used metrics when evaluating a company's true value.
Also, when black swan type Macro events occur... overvalued company's are the ones that fall the most because money managers know they're overvalued and they don't want to be left holding the bag so its a race for the exits.
Look at it like this...if fundamentals didn't matter, why would analysts across the entire finance industry pour over balance sheets quarterly? Trust me... they matter.
