Hackers Find New Way To Cheat On Wall Street
GMGruman writes "The high-speed trading exchanges that conduct the business of buying and selling stocks and mutual funds are so fast that hackers can introduce delays of a few microseconds completely unnoticed by today's network monitoring technology — and manipulate prices in the process to reap millions of dollars to the detriment of everyone else, InfoWorld's Bill Snyder reports. This kind of activity creates new reason to distrust Wall Street and shows how the computer networks we all rely on for conducting business and moving information are ripe for undetectable hacking."
I work in this business, and trust me - we count nanoseconds. We would notice if "hackers" were introducing delays.
AGH! You'll ruin the foundation of capitalism! Down with your regulations, you dirty commie!
That's not a news article, it's an advertisement.
High-frequency trading networks, which complete stock market transactions in microseconds, are vulnerable to manipulation by hackers who can inject tiny amounts of latency into them. By doing so, they can subtly change the course of trading and pocket profits of millions of dollars in just a few seconds, says Rony Kay, a former IBM research fellow and founder of a cPacket Networks, a Silicon Valley firm that develops chips and technologies for network monitoring and traffic analysis.
(emphasis mine)
A man who claims companies are losing millions due to network latency sells tools to monitor network latency? A reliable source, I'm sure.
That's what we hear, anyway, whenever anyone proposes that maybe ever-higher-speed trading isn't such a great idea.
It's a load of crap, of course. Yes, liquidity is good. No, restricting trades to, say, one per second -- which is still faster than any trading ever took place during the centuries of stock trading before computer trading became common -- would not bring our economy to a screeching halt. In fact, it would probably encourage economic growth by encouraging actual investing instead of the giant casino that the stock market has become.
Of course, in a casino, the house always wins, and since in the case the house also owns the House and the Senate too, this is never going to happen. Sigh.
The correlation between ignorance of statistics and using "correlation is not causation" as an argument is close to 1.
The reality of Wall Street ripping off the consumer is not far from reality. I work "in the industry" as well (and have, for 10 years), and I've seen and been witness to all kinds of shams and problems that Wall Street is culpable for.
Let's just leave it simply, the average investor doesn't know *anything* about investing. They don't know stocks, bonds, they don't know diversification, they don't know how to change allocations before retirement age for 401ks, etc. But the sad thing is, Wall Street doesn't either. They may know the P/E ratios of firms, the current stock price, and lots of fancy math, but the reality is that a lot of money made on Wall Street isn't in active trading, it's in knowing their customers and playing on that information, and topping it all off with fees. For example, Goldman advises its customers, and the clients lose out, and Goldman wins -- See here. This isn't uncommon.
The simplest secret about Wall Street is that the average investor can forgo using a trading firm, and just invest in an index fund instead (like the S&P). Those funds have very low fees, and require zero understanding about Wall Street. They go up as the economy gets better, they go down as it doesn't. And less than 20% of firms out there can *BEAT* the S&P, meaning that 80% actually do worse. In addition, they charge higher fees. So if you throw your money into the index fund, you don't have to know anything, and you do just as well as 80%+ of the firms out there, and keep the fees they'd charge you to just meet the same ROR in your pocket.
Sadly, you'll never hear about this on the Street, because it would ruin their whole scam. The only thing you need to know is that 5-10 years before retirement age, pull out of indexes and put into guaranteed products so you don't get thrashed on your retirement day, and you'll be a happy camper.
With the amount of influence Wall Street has in our government, in our economy, it's about due time we start getting them the hell out of the way so that we can do better as a country. I know it sounds cheesy, but it's true.
The price is always right if someone else is paying.
Back in my day Wall Streeters got money the old fashioned way, they bribed politicians to funnel taxpayer money into the firms while simultaneously getting the politicians to look the other way when banks committed crimes....whats that you say? They are still doing that? Well I guess somethings never change.
Now get off my lawn.....Whats that you say? The bank has illegally foreclosed on my property despite not actually being in debt to them and it's legally THEIR lawn now, and I'M the one that has to get off of it? Well, it's a good thing I have support from my local polit....ah fuck it.

Why not every 30? That should be enough time for a HUMAN to decide if they want to buy or sell something. It seems that this lightning fast trading works great and they're happy if they're making money. If something cascades into failure (like it did earlier last year, or was it '09?) then they just say 'oops, do over'. Imagine you were cashing out your 401k during the 'accidental' crash last year. One second stuff is at 1000, the next it's at 300. In the time it took for electrons to travel from your broker to the market.
The worth of a company what a stock is supposed to buy you into, doesn't change even from minute to minute.
I mean, they wouldn't make as much, but it'd be fair to the common person. (So it'll never happen). .. .. .. ..

OR, the other suggestion that I heard suggested would be to tax trades inversely proportional to how long they're held.
1 minute: 90%
1 hour: 80%
20 years: 5%
40 years: 1% (people that actually it as investment).
I've been an avid follower of /. for some time now. I've gained a lot of insight from reader responses, which are generally well thought-out, mature, and reasonable. On the topic of market microstructure, however, I feel /. falls woefully short. I cringe when I read comments that sound like something from Zero Hedge.
I work in HFT. I make markets. Obviously, there is an incentive for me to talk about all the good things HFT brings to the world. However, I also believe that we serve a function in the market. Perhaps not vital, but still a service nonetheless.
What do market makers add to the market? They're willing to stand on the other side of your trade. They serve a vital function to the market and we can trace them back to the specialist days on the floor. Let's all agree to start from there.
What do HFTs add to the market? Now this is where you have a large divide in opinion, and rightly so. Some HFT firms will engage in predatory behavior that is unfortunate, including quote stuffing and price manipulation. I am not writing to absolve all the bad things that many HFT firms do. However, in my view, ideally, HFT market makers add these factors: immediacy and continuity.
As an investor, you can go up to a trading terminal at any time in the day and someone (most likely an HFT firm) will be there to take the other side. That is immediacy. You also have access to price discovery that is happening every fraction of a second. That is continuity. These are ideal situations, and not every HFT adds these values. Firms that only remove liquidity are often not providing immediacy. Firms that manipulate prices are usually not providing continuity.
If you think, "HFT's will run at the sign of chaos!" I agree with you. The better, smarter, and faster firms will continue to stay in the market, but only up to a certain point. Why should anyone stand in the way when a big institution sells 75,000 ES contracts? We trade and provide liquidity so long as it's profitable. If you have a problem with that, you have a problem with capitalism. How do you possibly incentivize participants to absorb tail-end risk?
If you think, "But investors don't care about 30 microseconds!" I agree with you. The short reaction times are there so that we can manage risk. It indirectly adds value to the investor because it allows us to manage risk better, which allows us to provide really tight markets. Think about it. We're standing there for anyone in the world to trade against all the time. Adverse selection is the name of the game. Back in the specialist days, spreads were sometimes in dollars. Now they are in pennies, and in many liquid stocks, exactly a penny. I assure you -- if we ever move to a system that taxes each trade or throttles latencies, you will see spreads widen out immensely because it's harder to manage risk. If you impose a limit on the minimum life of a quote, you will see spreads widen because there's risk in standing in the middle of the highway for too long.
If you think, "But company values don't change every 30 microseconds!" I agree with you again. It's the possibility that they could change that necessitates high reaction speeds. Company valuations are stable -- on average. But once in a while, some information is leaked that damages the company's reputation or some big institution decides to buy a ton, and you're left with a huge position that's going against you. Should we stand there and absorb that flow even when it's not profitable?
The last point is probably the biggest factor in a gating system where trades only take effect every N seconds. You can only update your position every N seconds, so as a market maker, you're essentially putting out a lot more risk. Some firms will be smart about risk management and be able to provide tighter spreads and make money for themselves. Some firms will not and they will go out of business.
