Wait are you arguing for using fundamentals instead of price action?
anyway please no more strawmen. I didn’t say that strong form emh is true, I said semi-strong form is the what literally every manager believes (including buffet).
For the record EMH is seen as a classification of how mature a market is. Inefficient markets post wide bid/ask spread because there’s not a lot of info or liquidity. Semi-strong form efficiency means pretty tight spreads (most S&P stocks have b/a of a penny) and sufficient liquidity (Kyle limit). If all you use is the chart then you believe that all the info you need is in the price, which is actually what strong form EMH says. The one difference is that you make the illogical conclusion that you can use historical prices to generate a better model of fair value, whereas the authors of EMH would contend that you cannot. Considering that the most informed traders in the world (your citadel, Virtu, rentech) do not use Al brooks or “price action” trading, then it’s fairly safe to say that those using it are the uninformed and hence noise.
