Default How can one bad trade send stocks falling off a cliff?

Quote:
In one of the most dizzying half-hours in stock market history, the Dow plunged nearly 1,000 points before paring those losses in what possibly could have been a trader error
Wasent there another issue like this linked to trading software that caused a rather large burp?

Thank got it still has some resiancy and bounded back. Bet someone somewhere made a few bucks.

Computerized stock trading. Once a stock goes below a certain amount the system automatically tries to sell it. Apparently just one "oops" can create a runaway effect.

Anyone else get the feeling that our species relies too heavily on technology these days?

Two theories as to what happened - someone used B for Billion instead of M for Million on a sell order - or its fallout from greece.

There may have been a screwed up trade - but the market is going to get hammered by greece - and the shockwaves (which may be many euro nations defaulting) regardless.

If your in the market - get out... get out NOW!

Holy smokes a single keystroke can cause a crash?

That might need some looking in to.

Its easier than you think for one little screwup to balloon into a mess.

Back in 2004 I was working for a money management firm that handled high dollar clients. I had a standing order from the portfolio manager on this particular account to invest $1mm in 7-day commercial paper and to reinvest whenever it matured. So on this particular day, it was time to reinvest. So I get on the Bloomberg terminal and submit (what I thought was) my $1mm order.

Now when you buy commercial paper through the direct issuer order system on Bloomberg, you're dealing directly with the issuer (American Express, Chevron, etc.) and those trades are for all intents and purposes binding and final. The authorization is already set up in advance so you can execute the trades quickly each morning, as the commercial paper market moves quickly. By noon, the trading is pretty much done for the day. So anwyays, when you submit the order, the issuer sends the paper over and our settlement department wires the funds back and your trade is settled. Unlike regular bonds that have a trade date + 3 day settlement, commercial paper trades settle same day.

So about an hour after I sent the trade, I get a call from our settlement department saying that there's a $10mm order coming in and they're not sure what the deal is because I told them to be expecting a $1mm trade. My butt puckered. I immediately thought "Oh sh!t, I was a little happy on the '0' key, wasn't I?"

Luckily, the account had enough to cover the cost of the trade. I sold the extra $9mm back that same day and only had to eat about a $1000 loss, but it was not one of my greatest moments.

Quote:
Welt am Sonntag: Wird sich die Ursache überhaupt ermitteln lassen?

Müller: Kann sein, dass wir es tatsächlich nie erfahren werden. Aber eines weiß ich mit Sicherheit: Wenn in einem Umfeld größtmöglicher Nervosität, in dem wir über Staatspleiten im Euroraum und den Aufbruch des Währungsraums diskutieren, solch ein beispielloser Crash passiert, dann ist das bestimmt kein Zufall.

Welt am Sonntag: Das klingt ein bisschen arg nach Verschwörungstheorie. Können Sie das näher ausführen?

Müller: Aus dem angelsächsischen Raum heraus finden zurzeit konzertierte Angriffe auf den Euro statt, die die Investoren verunsichern sollen. US-Banken unterminieren mit Gerüchten um die Zahlungsfähigkeit Spaniens und einen Austritt Deutschlands aus der Euro-Zone das Vertrauen, und die Ratingagentur Standard and Poor’s stuft Griechenland-Anleihen genau dann auf „Ramsch“ herab, als das Rettungspaket eigentlich schon auf dem Weg ist.

Welt am Sonntag: Das Rating ist ein Spiegelbild der wirtschaftlichen Lage Griechenlands.

Müller: S & P gehört zum Mac-Graw-Hill-Konzern. Und dessen Vorstands-Chef Harold Mac Graw III war Berater des früheren Präsidenten George W. Bush. Ich behaupte: Bei S & P passiert nichts, ohne dass es nicht mit Washington abgestimmt wäre.

Welt am Sonntag: Verschwörungstheoretiker vertreten die These von der Existenz einer regierungsgesteuerten Börseneingreiftruppe, des „Plunge Protection Team“. Hat dieses PPT Ihrer Meinung nach auch am Donnerstag bei der wundersamen und schnellen Erholung der Märkte nach dem Kurssturz seine Hände im Spiel gehabt?

Müller: Das glaube ich in diesem Fall eher nicht. Wir hatten einen klassischen Sell-off, noch dazu einen extremen. Auf solche Situationen warten viele Marktteilnehmer. Ein Teil des Kursrutsches ging ja auf ausgelöste Limitverkäufe zurück, das heißt, Aktienpakete wurden automatisch verkauft, nachdem bestimmte Marken unterschritten worden sind. Irgendwo kommt dann immer der Wendepunkt, an dem die sogenannten starken Hände zugreifen und Aktien billig einsammeln.
I also recommend to check the Chinese stock index one day before the WS crash. there was a minor sneeze of -1.2%, due to some internal Chinese political things and announcements. It then travelled with the timezones around the glob, and just hours later the American market was shaking. Causal link? Randomness? Certainly a coincidence that surprises me that it was not noted by the media, whether it be for constructive reasoning or paranoic conspiration theory building.
