No, it means most traders get ruined by randomness. If you take a poll most traders will say the market is not random when in fact it is largely random but not 100% random. If you accept that then you can start to analyze the market in a way that generates consistent profits. The markets are nothing more than one gigantic random number generator in a time series. There are very powerful tools to analyze such a set of data and profit from it. Most folks are out there looking for ascending triangles or MACD crosses. All that stuff is garbage. Take the markets for what they are -- random number generators and let the winning begin.

Hi all. This is my first post.
There seems to be a fair amount of evidence that intraday stock prices move (mostly) randomly on short time scales.
My question then is what if you were a day trader and you randomly picked a buy point, and then a sell point every day, for a given stock. What would your long term average be (ignoring commissions) after many years?
If stock prices move randomly, it would seem that you would win and lose about the same amount on average, except for the long term trend in the stock price. Therefore, it seems like this strategy would simply follow the long term price movement of the stock.
However, I also read that most day traders LOSE money. Does that mean that most day traders do WORSE than random? That is, they are actually surprisingly skilled at doing poorly. If this is true, why? Seems like it can't just be the commissions, which I ignored above.
Would be curious to hear your thoughts on any of the above.
Thanks.
