How original of a thread idea! OP must have missed the thread on the same topic with 20K responses... Quick answer: yes, surgeries are BS because people die during surgery.
I think TA is mostly bullshit. A lot of studies show price just move on random Brownian motion. Case in point just take a chart and randomly draw lines and you will hit "significant" s/r's Anybody who thinks differently is just too far gone to let go or a newbie
What you do not realize is when you buy an index fund, you are essentially, following the major trend of the stockmarket. You may not be aware of it, but, essentially, you are applying and using the same principles of technical analysis, a major point of which is trend following. A lot of the so called hedge fund managers are not traders. They apply the same models created for them by academics and they are not risking their own monies. I would not trust those guys with my monies. I will trade it myself. The real good traders the likes of Paul Tudor Jones, Ed Seykota, etc. are featured in the Market Wizards book of Jack Schwager. As to buy and hold, you see Warren Buffet and a lot of people copy him. How many years has he held his position, 50 years? If you have that time, 50 years to wait, maybe, you will make a lot of monies. Then, again, if you have only 20 years after a huge, brutal bear market decimates your stocks, you may not even get your monies back and breakeven. I had CSCO and paid $120 per share then, during the Dotcom boom as a buy and hold investor which is how I started. CSCO is $39.60 today. Now, 22 years later, CSCO is nowhere near $120 per share. I lost a lot of monies on CSCO then. I lost a lot of monies then, holding onto CSCO. If I still had CSCO now, I would be down 67%, just on CSCO. What about my other stock holdings?
TA is not BS as a lot of good traders use it including, the best hedge fund managers. Just because you do not understand it and do not know how to use it, does not make it BS. Nobody is forcing you to use TA, nobody cares whether you use it or not. Spare us the nonsense.
There go the personal attacks. You cannot handle anyone contradicting you. Grow up, you are acting like a child.
