More traders should be doing technical analysis. It makes it easier to extract profit from them.
Or reading a vision statement, watching commercials, etc.... Because that is getting less technical and more feely.
With some exception (Tesla), technical analysis has major limitations. I don't really have time to figure out if a CEO has new back pain and started taking opioids.
There's a reason index funds are so popular. You hold a belief that growth will continue. You basically need that belief anyway when investing in individual companies.
