New "Circuit Breaker" Imposed To Stop Market Crash

Lucas123 writes "The SEC and national securities exchanges announced a new rule that would help curb market volatility and help to prevent 'flash crashes' like the one that took place on May 6, when the Dow dropped almost 1,000 points in a half hour. That crash was blamed in part on automated trading systems, which process buy and sell orders in milliseconds. The new rule would pause trading on individual stocks that fluctuate up or down 10% in a five-minute period. 'I believe that circuit breakers for individual securities across the exchanges would help to limit significant volatility,' the SEC's chairman said. 'They would also increase market transparency, bolster investor protection, and bring uniformity to decisions regarding trading halts in individual securities.'"

From that perspective, it's quite possible that the financial crisis would have been *worse* without Gramm-Leach-Bliley,

There were even calls to rein them in at the height of the bubble. There are videos on youtube of Barney Frank dressing down the regulator screaming that there is nothing wrong with Fannie Mae and Freddie Mac.

    Of course, we found out the truth a few years later.

    There is plenty of blame to go around. Trying to cast the sole blame on the lack of regulation is naive at best. At worst it is downright wrong and quite possibly dangerous.

    The problem with regulation is that it is always trying to prevent the previous crisis and not the next one. There will be another financial crisis. It will look nothing like this one. Any regulation we pass now will almost assuredly do nothing to prevent it. So do we really need to regulate to prevent the exact same crisis from happening again? Even without regulation, there is a strong argument that it won't happen again simply because market actors know better this time.

    Don't believe me? Not too long ago there was another financial crisis that resulted in greater regulation. The MCI-Worldcom and Enron Scandals. As a result, Congress passed Sarbanes-Oxley, which contained strong regulation in order to prevent MCI-Worldcom and Enron from happening again. Did Sarbanes-Oxley do anything to prevent the housing bubble and its subsequent collapse? Of course not. But it did result in billions of dollars being spent on compliance with new and complex requirements.

    On a side note, I often laugh when liberals talk about all the deregulation we've had. It's true, we've had a lot of deregulation. But to talk about that and ignore the many new regulations we've had, such as Sarbanes Oxley, is disingenuous, at best.

If you got burned because you were trying to make a profit intraday then you got what was coming to you, because not only are you not as fast as most of the firms out there, but also not as smart. (sorry) Frankly if NYSE's attempt to "restore order" wasn't so entirely broken the price discrepency would have been even shorter lived. However, because of the steps their market took to restore order most savvy shops immediately routed around them in order to complete and start new transactions (as they should). Attempts to regulate the markets in this way will not work as expected, because they are introducing arbitrary rules which will largely be ignored by the really big players (dark pools anyone?). So far there has been no indication that the recent price drop was the result of an HFT strategy gone awry, but rather a temporary blip made worse because of an outdated mode of operation. I think an interesting experiment would be if all of the HFT shops pulled their liquidity (this would never happen), the results would be fairly disastrous for short term investors, unless you like getting worse prices.

    Anyway, I don't want to rant any more. It is unfortunate that people aren't really looking at this from all angles. Competition is a good thing for everyone. It applies to Microsoft and Linux, but not the markets right? ...

    What exactly is the "true value of the stock"? If your answer has anything to do with the future (future revenue, future earnings, etc.), please explain how you're able to know the "true value" of anything which has yet to happen.

    This is an excellent point. No healthy public companies are trading wholly on their intrinsic value.

    The intrinsic value (this is hardly the proper GAAP term, so I'm defining it briefly here) would be taking all of XYZ Company's assets and receivables and summing them. Then dividing amongst the "float" (number of shares issued).

    So if XYZ has $1M in the bank, and is owed $500k (and we assume it's all collectable debt), then their value would be $1.5M. If they have one million shares issued, those shares are worth $1.50?

    That's hardly how it works.

    Why? The shares don't disappear into thin air at the end of their fiscal year. They'll make more money next year, and the year after that. But they might go bankrupt, or become obsolete in the market. We can't know these things with certainty, so we price the stocks accordingly ("risk"). But wait, what if they sign a big deal and suddenly their receivables go way up for this year? Well that's called speculation.

    So now you have the way modern fixed equities (stocks in companies) are priced on our markets. Actual monetary value if the company was sold, plus or minus speculation/risk on perceived future monetary value. Oh, plus dividends, but those aren't nearly as important as they used to be.

    TL;DR- It's not simple like you want it to be, and it shouldn't be. Speculation drives access to capital.

    You just bought company X stock and you hear on the news that they're going belly up 10 hours from now. Who the fuck is going to buy it?

    Further up somebody gave an example of an event occurring which bankrupts a company, and everyone appears to have latched onto this as being a description of the typical scenario.

    Much more likely is some news that damages a company. If you think the market has overreacted it would make sense to invest in the company and wait for the bounce.

    In 24 hours everybody's Bankrupt Ford stock will be worth $0.00 (or mere pennies).

    No. The stocks will be worthless immediately as soon as Ford announces the bankruptcy.

    when he has advanced knowledge of Ford's bankruptcy,

    The whole point of 1-day trading is to prevent people from exploiting information asymmetry, and your only excuse is that you want to continue to exploit it? It looks like you kind of didn't get the point of the grandparent at all.

    Connecting buyers and sellers is what the exchange is for. In your example the buyer was raped off of 1 dolar, he should get the stock for $49, but someone stepped in front of him and masked out the real ask price.
