How to Make a Risk-Free Fortune on Wall Street

Redline Trading Solutions recently allowed Berkeley professor Terrence Hendershott to conduct a study with its high-speed trading technology, which gave him access to stock prices a few milliseconds before everyone else. This meant that Hendershott knew, before he bought the stock, which way the price would move a fraction of a second later. As you might expect, this is a risk-free license to mint money:

According to his study, in one day (May 9), playing one stock (Apple), Hendershott walked away with almost $377,000 in theoretical profits by picking off quotes on various exchanges that were fractions of a second out of date. Extrapolate that number to reflect the thousands of stocks trading electronically in the U.S., and it’s clear that high-frequency traders are making billions of dollars a year on a simple quirk in the electronic stock market.

One way or another, that money is coming out of your retirement account. Think of it like the old movie The Sting. High-speed traders already know who has won the horse race when your mutual fund manager lays his bet. You’re guaranteed to come out a loser. You’re losing in small increments, but every mickle makes a muckle — especially in a tough market.

“It’s clear to us these guys are just raping, pillaging, and plundering the market,” as Joe Saluzzi, co-founder of agency brokerage Themis Trading put it.

In practice, stock markets are never going to be fair to every participant, but at the very least, their rules are supposed to make them theoretically fair to all comers. High-speed trading makes a mockery of this.

Dear Reader,

This feels like the most important fundraising drive since I've been CEO of Mother Jones, with staggeringly high stakes and so much uncertainty. In "News Is Just Like Waste Management," I try to unpack the reality we all face and how we can rise to the challenge. If you're able to, this is a critical moment to support Mother Jones’ nonprofit journalism: We need to raise $400,000 to help cover the vital reporting projects we have planned, and right now is no time to pull back.
