When Markets Go Awry: The Need for Humans

Last Thursday's short lived intraday 1000+ point market dive and subsequent recovery, a "Flash Crash",  raises some big questions on the stability and quality of our electronic market system.

The new age of technology and computers was heralded on Wall Street with the computerization of the market exchanges. Conversely, the NYSE was seen as being antiquated with their manually managed open call system where a human market maker determined the prices of the bid and ask of stocks.

Yet, the May 6 debacle showed that we may have gone too far too fast. The 20 minute cliff dive seen is still being investigated as to what caused it. So far it is believed to have been triggered by a CitiBank trader who mistakenly executed a billion dollar sale over the intended million dollar execution. This allegedly triggered a chain reaction among all the automated trading systems who read the market activity as a big sale trigger.

Now CitiBank is denying that they had anything to do with it, and the other problems that occurred certainly can't be blamed on them. For all we know, someone could have hacked into the system like in the movie WarGames and played "Stock Market Crash" instead of Global Thermal Nuclear War.

The market dive was interesting in that it was done on low volume- not a big volume dump that would truly indicate widespread panic selling. Other big problems was stocks were being mispriced at either pennies or over a hundred thousand dollars. Regardless of what triggered it, there was a definite error in the system as the markets went haywire.

There was one market that didn't go haywire - it was the believed "antiquated" NYSE who still has humans setting the market prices for their stocks. They saw the aberrant pricing and decided to slow down the trading action while the they checked the validity of the stock prices. The meant that trades were not being executed instantly, but had a delay of 30 seconds or so. The other electronic markets traded past the NYSE and ran with the given prices. This resulted in the NYSE being the only market that was still open during that time that maintained sanity in their stock pricing. They were also the first to decide to cancel any automated orders that were part of NYSE (ARCA) that happened with the erroneous pricing.

The news may be playing it down, but what happened that day was a SERIOUS malfunction of the US automated trading market, and could have had grave consequences on the worlds economies. During that time, it looked like the market was on its way to completely collapsing, and any one witnessing that would be inspired to sell and keep selling. There were also stop loss orders that would have been triggered taking people out of their positions at the lows of the day. This unfortunately adds more tarnish to the US financial system, which already has a black eye from the dubious actions of the major investment banks which are being blamed as the primary cause of the current Great Recession. If our market stability comes into question, it would gravely impact international money coming into America, not to mention our own security and peace of mind.

Canceling all the trades that occurred with crazy pricing was the right thing to do, as this wasn't triggered by real world events, but an error in the system. If the trades were allowed to stand, that would mean that people would have lost and made money based on a computer error which would seriously undermine the security and safety of our markets. It would be like a bank making an error with their accounts giving some people more money and taking away money from others, and then saying it was going to let those errors stand. That bank wouldn't be in business much longer if they went that route.

It also shows you the limitations of our current computer technology. Without a human mind in the system to evaluate the validity of the trade during volatile times, the market was more than willing to trade at whatever prices it received. With the myriad of worldwide financial news being taken into consideration, there are just too many factors to consider to think a computer can be programmed to take all of these into account and come up with a sound judgment - our technology is no where close to that.

You can be sure that more regulations are on the way to bring more stability to the markets, which is a good thing. An error like the one we experienced will most likely be triggered again on perhaps an even bigger scale unless proper checks are put into place. The current checks are not enough- the first built in market slow down is only triggered at a 10% intraday market drop. We were close to that, but didn't hit that number. Perhaps that number should be reduced to a lower number like 5% or 7%. Our current checks are now only meant to slow down a falling market, so there is nothing stopping the market from being bid up to the moon in one day with no forced time outs- this doesn't sound very safe either.

Stock Meltdown and Whipsaw: Robots Gone Wild

5/06/2010 05:25:00 PM / Posted by Soullfire / comments (0)

Today was another historic day in the markets - it was the greatest intraday plunge since 1987. This was matched by the mother of all whipsaws when the market dived over 650 points in just 15 minutes bringing the Dow loss to over 1000 points, only to surge back up over 600 points in just 8 minutes. To put it another way, the Dow moved over 1250 points in just about 23 minutes.


As you can see, the market literally falls off a cliff and then rapidly recovers much of the loss. That's an incredible amount of volatility!

Here's what it look like on the S&P 500:


As this was going on CNBC had live video of people rioting in Greece over the govt approved austerity measures as they try to climb out of their debt problem.

Just remember as you see these countries in financial turmoil, that much of the damage was caused by them having toxic CDO assets that went worthless. This is the gift the big investment banks have given to the world....yet you still have folks trying to justify their existence instead of scaling them back.

This super-sized whipsaw most likely caused big casualties in the market today. All those who had stop loss orders placed most likely had them triggered as the market plunged. It's never fun to get stopped out of a position, only to have the market reverse and go higher. The market got me to cough up some shares before the real dive happened - thanks heaven I pulled the plug early!

The next set of victims were day traders- the human ones. The market moved so fast that if you weren't fast enough, you were likely to either get burned on the way down, on the way up, or from both sides. I made a few mistakes and got singed here too. I'm sure a few folks manages to capitalize and make some money if they timed it right.

The third set of victims were the robot day traders. What ever triggered this dive (they are still investigating) took everyone by surprise and the machines just exacerbated the moves as their algorithms went with the flow. I'm sure some auto trading machines fared very poorly.

The only folks who escaped that whip were the ones ignoring the market. Of course, the aren't completely unscathed as the market still ended the day with over 3% losses.


NYSE (ARCA) and NASDAQ have announced that the are canceling ALL trades that happened during the plunge/whipsaw for stocks that were more than 60% off were they were trading before the big moves. Not sure how this will be tallied in...

Apparently the latest track is that some traders fat fingered an execution and instead of executing a million trade sell, he triggered a BILLION execution instead.

No Country for Old Men...or Humans

Now there is talk about more regulations needed to control the level and timing of trading. With hyper fast trading, computers can now process and work on over 1000 bid/offers per second. There's no way humans can compete with that on the short term. Manual trading gets safer the farther out you go in the time line as you have the longer term trends to support you.

Now everyone is getting worried again after months of "happy times are here again" complacency.

To be ahead of the game, all one can really do is stick to technical and trend analysis. Don't base your decisions on the news or emotions, but keep them in mind in the background. The long term trends should be the primary markers to show you whether to be buying or selling.

It's is interesting that turmoil in Greece can send sink our markets as well. It just shows you how connected we are. Don't you find it strange though that when Greece first announced that had problems several weeks ago, the market shrugged it off and moved higher? This is why you can't trade solely on news.

As I've said in a prior post, fundamentals ALWAYS catch up to the market eventually despite the market's willingness to ignore it for an extended time. This market is to be traded - buy and hold is high risk at this time.
