Do technical indicators actually work while analyzing stocks? [duplicate]
Sure they work - right until they don't. Explanation: A stock picking strategy based on technical indicators is at worst a mix of random guessing and confirmation bias, which will "work" only due to luck.  At best, it exploits a systematic inefficiency of the market. And any such inefficiency will automatically disappear when it is exploited by many traders. If it's published in a book, it is pretty much guaranteed not to work anymore. Oh, and you only get to know in hindsight (if at all) which of the two cases above applies to any given strategy.
Below is an instruction that describes a task. Write a response that appropriately completes the request.
