this just proves the market isnt rational which is great for investors. Sounds like you are just too foolish to understand this. Markets are a result of human psychology, nothing more nothing less. Humans are fallible..You arent really some genius cause youve found out the markets aren't efficient mechanisms to determine value lol.
Honestly sounds like you are 20 years old (or 40+) and trying to be smart...You come across as idiotic though. And you also sound like a retail investor. Number one thing youll hear at cocktail parties full of doctors and lawyers is "MARKET IS SO RIGGED", "MARKET IS SO DUMB BLAH BLAH".
Inefficiency in price allow a real investor to have opportunities. If everything was priced perfectly there would be real reason to invest...
Yeah, markets are often quite inefficient in the short term. They tend to be pretty efficient overall in the longer term, although certainly nowhere near 100%. This is fundamental to the investing of Graham, Buffett, and many other rich old men who usually started with very little.
I've bought good companies very cheaply thousands of times after they sold off HARD due to a market over-correction on something like earnings news that was good that the street didn't like for whatever reason, or short term problems with a drug approval, or whatever. They may have perhaps been a little high before the news, and temporarily became irrationally low after.
I've also made quite a bit of money on the short side on many irrational bubbles / micro-bubbles - but you have to be more careful there due to the theoretically unlimited downside risk and limited upside when going short... plus the general upward bias of the markets and stocks trading on exchanges that exists for various reasons.
I think the big problem many have with stocks, bonds, commodities "paper", etc is that you can always see what the price is, and are always aware of an investment's current perceived value, which is not always rational and often constantly changes due to various factors and bids and asks of large numbers of outsiders. If you could put shares of your home, investment properties, private business, etc, up for auction every day in a public exchange, the same thing would happen.
There's always risk with any investment - stocks and bonds, commodities, real estate, drilling oil, private businesses, etc. I'd generally rather buy shares of promising publicly traded companies that have to disclose everything than buy private companies that don't have the same transparency requirements. I invest mainly on fundamentals. Have done quite well over 21 years, although it's not been anywhere near perfect.
