It's simple, money managers found out they didn't have the stomach for trading or couldn't get a knack for it. It's not for everyone, it's not for most, so they do something more docile. I don't want to debate tickers, the example I gave you are the market definition of mature companies. Startups are growth companies, not IBM, GE, Coca Cola, or Boeing.
There's no "market obsolescence." Big money and the MMs are running the exact same games they've been running for 100 years, none of it's changed other than it's done with computers. It hasn't changed because it works. Same games. If you understand the market is 100% manipulated 100% of the time, you study their game, how they do it, so you can read their intent, trade with them, and not getting steered where they want you. If you understand where they're steering traders with fear, you play their game better. Anyone who got "run out," did so only because they didn't manage position size well, which is 90% of traders, based on the only reason traders lose money - - emotion.
I appreciate the offer for a private chat, but you seem less interested in improving craft, and more about expressing beliefs, which doesn't create a learning environment either direction. I was mentored from deep insiders how the market works (from the inside). It was shocking at first, but cool once you accept and understand "the game behind the game," then learn how to play it. I can tell you twenty ways til Sunday how everything is manipulated, how to read and play it, but it takes time and practice to use that intel in real time. I can't force you to be interested. If it's not a passion, it's not. I've helped a lot of people change their trading for better, more consistent gains, but the ones who do so have open hearts.
You have opinions, which is fine, it's just that many of the "scary" market beliefs you hold can be demystified if you put the work into craft, in the right way, to understand "the game behind the game."
Have a great weekend.
