High-Speed Firms Now Oversee Almost All Stocks At NYSE Floor (bloomberg.com)
An anonymous reader writes: Barclays, one of the biggest banking and financial services firms in the world, has sold its business on the floor of the New York Stock Exchange to Global Trading Systems. This is significant because it marks a transition between human-based trading and high-speed trading. Now, humans on the NYSE floor have more of a supervisory role, making sure the automated systems don't go haywire. Barclays has been around for hundreds of years; GTS was founded in 2006. "There used to be dozens of specialist firms, as designated market makers were once known, at the NYSE floor. But profits from trading U.S. stocks dwindled, making it difficult to serve as market makers without automation. Although GTS, Virtu, IMC and KCG employ human traders at the floor, their businesses are driven by some of the industry's most sophisticated computer systems."
Honestly, they might as well replace all the workers in the trading system with robots. None of this produce real wealth anymore. The original idea of the stock exchange was to allocate capital efficiently from savers to businesses that could use it to create productivity growth. But we haven't had a capital constrained economy for almost two decades now. Banks can create whatever capital they want (or can fool you into believing in) using debt-equity fudges, and current negative real interest rates on cash indicate that the problem is not capital availability but consumer demand.
When you have no capital constraints the stock market 'value' is determined almost entirely by hype. Even worse, private equity funds are so big now that they can ensure the public exchanges never see any of the juiciest profit making companies until they are fully asset stripped and ready to pump and dump.
I'd be fine with this, if they weren't allowed to unwind transactions because of "computer glitches". If they wanna automate trading, they should have to take the good and the bad. But now, if their software does something stupid (like repeatedly buying at 25.01, and selling at 25 even) and you take advantage of it, they sue you and get the trades reversed.
Your ad here. Ask me how!
Computers, may trade faster, smarter, whatever, the question is do they actually add any real value to the economy, or just skim off the top from the actual people that produce the goods and services. I think it is the latter, like human stock brokers, but much better at it. Do we really need a better parasite?
Okay, but can you provide evidence they were wrong about this?
Of course not. He cannot even provide a theoretical reason why faster transactions would lead to instability. Systems with hysteresis, or lag, tend to have less stability (ask any helicopter pilot). In theory, faster transactions should lead to more stability, and this is true in practice as well.
HFT is good for market stability, good for retail investors (far lower transaction costs), and, by making capital markets more efficient, good for the overall economy. The only losers are the old inefficient and expensive brokerages, which mostly no longer exist. Good riddance.
