It’s not impossible, there are many people who make decent money from day trading. It might be more accurate to say “study shows it is difficult to earn a living trading stocks”

The abstract, of course, contains more detail than the headline regarding exactly what is claimed:

> We show that it is virtually impossible for an individual to day trade for a living, contrary to what course providers claim. We observe all individuals who began to day trade between 2013 and 2015 in the Brazilian equity futures market, the third in terms of volume in the world, and persisted for at least 300 days: 97% of them lost money, only 0.4% earned more than a bank teller (US$54 per day), and the top individual earned only US$310 per day with great risk (a standard deviation of US$2,560). Additionally, we find no evidence of learning by day trading.

The interesting bit to me is, “we find no evidence of learning by day trading”. This implies to me that the top earners are merely lucky, and have no special knowledge or advantages.

Probably very similar to results for people who try to make a living gambling in casinos.

Not impossible but highly unlikely probably means impossible, practically speaking.

Unfortunately this falls into the "too good to be true" category. A very unscientific categorization but surprisingly accurate in real life.

To me the worst conclusion is that "Additionally, we find no evidence of learning by day trading." Which leads me to believe that despite your best efforts at obtaining knowledge, luck in timing still plays too much of a role in the outcome. That doesn't add up to a viable alternative to a regular day job.

And the article even moreso:

> "We follow all individuals who day traded mini-Ibovespa futures contracts for their first time from 2013 to 2015, a total of 19,646 individuals."

I know nothing about the Brazilian equities market, but it seems like it might be harder to for individuals to reliably make a profit on something heavily traded and fungible (Ibovespa is an index), where you're competing with much bigger players. Smaller stuff might work better--for one person--because it doesn't scale.

I don't doubt the headline, but "We observe all individuals who began to day trade between 2013 and 2015 in the Brazilian equity futures market" seems like a weird way to come to that conclusion.

Looking at how bad these results are, the career gamblers in the casino seem to have an edge. They have various strategies that actually do work to greater or lesser degree - e.g. Playing poker which is a game of skill against other people with a house rake instead of a house mathematical edge.

It could also imply that they simply have related experience or skills before starting.

It's difficult to, for example, learn how to become a brain surgeon on the job.
