NYSE says Electronic Trading Black Box for plunge

Quote from total_keops:

Remarks, this is what it is. A poem nothing less. "It's that V-shaped drop where it came down and snaped back right back up". Sir, why dont you look at the drop in 2008: It was a V-shaped drop where it came down and snaped back right back up. Was is for real then?
Chearleader.

You may have found the 2008 a snap right back, and for real, but I lost a fair anount of money on that Lehman slide.

I was green today. Big difference. Enough to buy a car.

Electronic Trading to Blame for Plunge, NYSE’s Leibowitz Says

May 6 (Bloomberg) -- Computerized trades sent to electronic networks turned an orderly stock market decline into a rout today, according to Larry Leibowitz, the chief operating officer of NYSE Euronext.

While the first half of the Dow Jones Industrial Average’s 998.5-point plunge probably reflected normal trading, the selloff snowballed because of orders sent to venues with no investors willing to match them, Leibowitz said in an interview on Bloomberg Television.

“If you look at the charts you can see fairly clearly where the trades came in,” he said from New York. “It’s that V-shaped drop where it came down and snapped right back up. You had some very high-cap stocks trading down 50 percent or large percentages in a split instant because there really was no liquidity in electronic markets.”

The selloff briefly erased more than $1 trillion in market value as the Dow average tumbled 9.2 percent, its biggest intraday percentage loss since 1987, before paring the drop.

Larry's mostly right, just a little bit slow getting it into print. I said about the same thing an hour earlier, here:

Said it hours earlier elsewhere, links on request.

He's wrong in saying there was no liquidity.

There was TONS of liquidity, more than we've seen for a long time, maybe ever.

Problem was, there was twenty tons of volume at the same time, so comparitively, there wasn't ENOUGH liquidity.

Computerized trading has its plusses and minuses, but today, we became aware of a new, major minus.

When a climate of unease prevails, and significant events related to the climate of unease occur, a computerized market can go to zero, then 100,000, then zero, then back to open, within nano-seconds.

I don't know how smart Obama's minions are, but if they realize what I knew hours ago, on this subject, and combine it with what is likely in Greece, Germany and GB tomorrow, our markets may open late, or not at all.

If Obama remains clueless, we stand into grave risk. Collapse is always possible, it's part of the game. Today we were shown what instant, accidental collapse might look like, a battered and bruised, but otherwise sound (for the moment), market, coming within a gnat's whisker of collapse, due to one strategically minor trigger, leveraged by massive hyper-connectivity.

exactly! no busted trades. Screw em.

And by the way when is the last time you saw trades busted on the upside?? NEVER

Now, c'mon, we all knows bulls are whinos with bigger pricks than bears. :D

Those morons will always rationalize when they're in trouble.

But hey, let's blame it on the black box boogy man. It's convenient. And, we can reinforce it with riots in Greece and oil spills. "They'll" buy it.

This is just another flavour of the public needing to "know" why the market went up or down on a given day. The volatility was to be expected at this point in the market - we have been weak and trickling down for several days now. The range was twice what could have been expected, however the over extension was bought back up in any case, so we close down 4% rather than 10% - the latter was never reasonable.

The curve down was the same reason as always - multiple levels of stops placed by late bulls (long above 1200, 2000, 11000 etc) and competitive liquidation with no serious professional buying in sight as they see no floor.
 
Quote from Angrycat:

Totally agree. But if your goddamn black box is too stupid to know when to stop fucking selling, then you should eat the loss. Why should their trades be busted? Why are good traders (and good black box makers, for that matter - the good ones know when to stop) have to subsidize the idiots?

The Aristocracy of Pull.

And you arguments to prove that it was otherwise are?
 
Quote from Chuck Krug:

I doubt it that black boxes are to blame.
There just weren't any buyers for a while.

Exactly. But the establishment can't deal with that reality so they cancel trades. Joke.
 
Quote from risktaker:

Another reason to get rid of this black box, algorithmic, bullshit type of 'trading'. It turns the 'market' into a casino. This kind of garbage didn't happen in other countries/exchanges that don't suck up to these bogus leeches/ aka "liquidity providers".

So how much did you lose yesterday? Your screen name makes your post even more ironic...
