Naturally, the article was about whether this is fair and ethical, with a pretty strong sense of no (and surely pressure on the University of Michigan not to offer the service.)
It didn't ask the obvious question: Traders need willing counterparties. Knowing that this is going on, who in their right mind is leaving limit orders on the books in the two seconds before the confidence surveys come out?
OK, you say, mom and pop are too unsophisticated to know what's going on. But even mom and pop place their orders through institutions which use trading algorithms to minimize price impact. It takes one line of code to add "do not leave limit orders in place during the two seconds before the consumer confidence surveys come out."
In short, the article leaves this impression that investors are getting taken. But it's so easy to avoid being taken, so it seems a bit of a puzzle that anyone can make money at this game.
I hope readers with more market experience than I can answer the puzzle: Who is it out there that is dumb enough to leave limit orders for S&P500 ETFs outstanding in the 2 seconds before the consumer confidence surveys come out?
