The tired coin flipping trope is just dismissive and does nothing to seriously argue against the possibility of people consistently beating the market. Even Warren Buffett, the champion of index funds, has argued against the coin flipping analogy. I've had this discussion several times before, so in lieu of rehashing it I'll just put this here: https://news.ycombinator.com/item?id=13451161#13452516 https://news.ycombinator.com/item?id=13451161#13452516 Empirically map your coin flipping analogy to a probabilistic model of the likelihood of beating the market and then we can reasonably talk about it. There are real arguments to be made, but saying "coin flipping!" does nothing to seriously engage with the debate.
