Well, there would be many things that are unclear to me about this. Like, even though you have a method for finding "value", you still need to figure out whether the current market price is lower or higher than it should be. How do you figure that out? And how does one define "panic selling"? Are there metrics for measuring that, or do you just say that any time the price goes down someone is panic selling?
The advantage of using a formula is that you can make rigorous statistical tests of your claims using historical data.
I mean I can't,
Imo, this is how I view stocks and stock like assets, as foolish as you might see it,
The problem with investing in general (or at least in stocks that don't pay dividends) is that the price can be an entirely subjective evaluation. Holding stock can give someone a percentage of the company, but its value in liquidity usually isn't anywhere near the price you pay for the stock. The stock market includes all types of people that invest for many different reasons. Sometimes things goes up in price simply because it sounds like the next big thing and people want to be 1st in, despite the fact that if it's popular, they probably missed the boat already.
For example, I invested some money in ethereum at $14, it went to $20, then crashed to $8 because of the DAO "hack". Details aside, I still believed in the crypto as something businesses might adopt because of its contracts and ability to create your own crypto backend on top of the network; and it has backing of major banks. But anyway, I held on to those coins and now I think they are worth ~$190. And why did it go up in price? No one seems to know, but there's been a lot of good press about ethereum, some banks and businesses are making plans to use it (including the us government) and a lot of ICOs have taken advantage of it as well. I don't have charts or graphs, but the DAO "hack" created panic selling that didn't somehow mean ethereum was going to die. The crypto still had value.
Another example, when Steve Jobs died, investors became worried about Apple continuing its success without him. The stock dipped, but Apple isn't Steve Jobs and the company seems to still be successful. Panic selling.
Or take amazon. The company is continually expanding and spending money in research and improvement. So its profit margins are low. Yet people are willing to buy into the stock at values that don't justify the asset liquidity of the stock or its profit margins. So why is it so expensive? Personally, I think it's popularity. Amazon continually gets more and more good press as it becomes the walmart of the internet and more and more people use it. I did hold on to some amazon stock for a bit, but sold it a while ago, as I feel uneasy about how high the price has gotten. Doesn't mean it won't go to $2000 or $3000 or whatever before hitting a bubble and crashing as soon as Amazon finds some kind of trouble, but I'm not comfortable with its price. And I don't believe the cloud computing and drones and Alexa computers are going to become that profitable. I mean let's be honest, Alexa is kind of a gimmick, Google, microsoft, oracle, etc. also do cloud computing, and drones only work well in cities where it's easy to fly somewhere than drive through congestion (not that it won't help cuts costs there overall, but they are expensive and delicate aerospace machines and it won't be an amazing thing for the same reason we drive cars and not airplanes).
Does that give you an idea where I'm coming from?
