I'm old. I remember when they used to teach Capital Asset Pricing Model and ignored everything else. My first degree was in the early 90s from Penn State. Technicals weren't even an issue. All the Profs did was talk about CAPM until your ears bled. How boring.
Later, if you mentioned technicals, they laughed you out of the room. I used to tell people they didn't know jack using that technical voodoo. But things have changed.
The technicals vs fundamentals issue used to make for a pretty big argument among Finance types. In the early 2000s, if you wanted to start a no-holds barred argument, say one was better than the other and run.
