I'm sorry Dave, I can't do that right now.

Daisy...Daisy...

Dave, the pod bay door is 30% open.  I know you can't get into the safety of the bay until it is 100% open - but it is partially open.  Is that acceptable to you?

My - my!  Such language!  I'm reading your lips now so be careful...

As you can expect my estimate has been taken out of context quite regularly by the MSM. At its height in 2009, I had HFT at 61% of the market. Nowawdays, it has declined to 56% and could fall another couple of percentage point by year end. The reason for the meteoric rise and subsquent fall are related. As another poster indicated, a lot of buy-and-hold money exited the market in Q408, which left active retail traders, who tend to execute against HFT fairly often, as a higher percentage of overall market volumes. It was also a very volatile period, another positive for HFT.

However, 2010 has been relatively calm in US equities. In addiiton, YOY volumes have been down in every month this year except May. But a somewhat counterintuitive trend has crept up in all of this. As ZH readers well know, money has been pouring out of US equity mutual funds. You would think this would mean they have become a smaller player in US equity volume. Not true. The declines in fund management have been less meaningful than the drop in volume. So institutional investors are actually a bigger part of the volume in 2010 than a year ago.

In conclusion: as volume and volatility dissipate, those strategies that feed on it are dropping off quicker than longer term players even as those funds bleed money too.

givens. high frequency trading. flash crash. rigged markets. insider trading. market manipulation. front running. market makers. dark pools. the fed. plunger teams. hedge funds. ...

the excuses are there are NO EXCUSES.

no matter the market rules or givens.

traders will find a way to exploit them.

traders are opportunist.

when a trader sees money laying in the street. wall street. a trader will pick it up.

pretty simple.

my trading buddy. hi.five.oh.

a retail trader trading from a bedroom trading room started in 1993 with $50,000 went up to $6,000,000, down to $600,000, up to $10,000,000, now at $5,000,000.

a trader is at the mercy of one’s own ignorance.

naive: deficient in worldly wisdom or informed judgment.

whose game does a trader play?

if a trader does not know whose game one is playing, trading is an expensive way to find out.

learn to trade.

a trader trading a complete trading plan will continuously make more money than one loses.

Don't understand all this kvetching about HFT- If they take out 8 billion anually (or .0024 per share) in trading profits, that's peanuts compared to what the market makers took out under the old regime of 1/8 minimum bid-ask spreads. If they were doing serious manipulation, their trading profits would be much higher.

Exactly.  The only issue is that this amount of money is now concentrated in fewer hands.  Before it was 5,000 floor traders across the major exchanges.  Now, 40-60 firms get it all.

 dude, if everything is a fraud, so is gold.

 what are you going to do with it? ok, so you could drop it from a high place onto your head and end the suffering, but shy of that.....

 

Mr. E's picture

Of course, most trades have always been done by market makers and speculators.   Anyone who ever traded in a pit will tell you this...   CME S&Ps (not e-Minis), beans, bonds, notes, eurodollars.

 

Market makers and short term speculators always account for more than 50% of the volume  in a liquid market.

Will be interesting when it accounts for 99% of all the trades.  I'm 95% out of the market and the remaining 5% is for short term to stay in practice.  Between HFT, and all the SEC, fund, 401, and IRS rules for us little guys I feel safer letting inflation take my assets.

A stock is a piece of paper backed by the full faith and credit of nothing. Much like Treasuries are on the verge of becoming.

Hey Mac. See you're out doing it doggy! Is Marcia Brady okay? And I hope you are the same Mac I talk to from time to time or this will make NO SENSE.

In response to your post: All of it. I would say fractional reserve "everythinging" or something but that assumes someone reserved a ratio of something of value somewhere. We are all morons trading pieces of paper for stuff at every level. It is that bad.

I think this bears repeating IT IS THAT BAD.

Hope you get this. I leave you messages from time to time, you have been very nice, if a bit edgy. :-)

Great post GW.........meaning comes from context.......your question puts context into perspective. Tnx many x.

of course the markets are manipulated. now, the methodology is refined enough to automate the process. the numbers are counted by computer.

HFT is obviously contributing heavily to the lack of healthy variability in the market, but what else would you expect after most non-robot investors rushed for the exits in 2008-09 and are continuing to do so in 2010. Someone (or something) had to step in and do most of the trading so that the power elite structure could maintain the illusion of stability.

Someone (or something) had to step in....

If you are saying that the bankers/brokers needed a new way to allow continued harvesting of profits at insane levels, I'd agree.  If you're saying that HFT is needed to provide market liquidity removed by the mass exodus of meat-based lifeforms, I disagree.

I occasionally trade pink sheet issues.  Securities where, on good days, all of 20,000 shares will trade hands, at less than a buck a share.  You learn real quick when trading illiquid securities to avoid entering in orders coded "market".   Do so and your buy of 4k shares may clear out the first 15 of the entire 40 limit orders on the order book, just waiting for your open ended order to come along, and you fill in 15 parts at an aggregate price well and away from what you saw on the quote when placing the order.  Buy or sell, "market" is asking for a surprise with pink sheets.

But I and others like me learn, and get by just fine.  We learn that the price quoted is an "imputed" price, one that tries to represent the value of all outstanding shares, but does so from the trading activity of a very few.  It is the price you have a chance of getting, if you and others don't all try to buy/sell at the same time.  It is in no way fixed, or particularly reliable, just something along the lines of a strong hint; and it isn't detached from trading volume AT ALL. 

Seems to me that view of pricing ought to apply to *everything* in markets, and people would be a lot more realistic about their holdings if they had to continually take liquidity issues into account.  AAPL closed at $305.24 today.  There 915 million shares outstanding, and I bet every AAPL owner who checks his portfolio looks at his extended balances and thinks "so that's where I'm at today".  But the truth is different; that's only where you're at if things remain relatively unchanged.  Pretending that quoted prices are somehow firm, real and reliable is yet one more disservice being done to the body of investors; it pretends to remove yet one more symptom of the risk they're taking by being in the markets in the first place.

The liquidity provided by HFT isn't needed by investors, and arguing for sanctioned pillaging by the big firms as some sort of "good medicine" is pretty thin.  It is a crutch that keeps people from assessing their true situation as participants in a free market.  We are all big boys and girls, and I for one would welcome markets with HFT banned.  We can all figure out how to deal with the lack of liquidity should that be a consequence; we did fine in the markets *prior* to the advent of HFT...

So with the range of 40-70% of volume are HFT.   Doesn't that mean that 40-70% of the trading has little or nothing to do with the fundamental shape of companies and the health of the economy?   It's all to do with extreme short term technical and manipulation of prices?

 

How could anyone justify using any existing logic in that type of market would be illogical.

GW, I have a different question, that dovetails this one: What Percentage of U.S. Equity Trades Are Underpinned by Fraud?

desk-jockey's picture

all of them sister. all of them.

shammy sham shamalamadingdohhhh.

MsCreant's picture

It makes everything a fraud, doesn't it? No limits. Fraud money, stock, treasuries, ETF. I see why gold has appeal.

The system has become absurd because it is all shamalamadingdohhhh.

My opinion, for what it's worth, is common stocks are inherently worthless to begin with.

My premise.

The shares are issued. The money is collected, minus issuance fees, by the company. The money is then used for whatever the company wishes. The buyer is left with a "receipt"...the stock...good for only what someone else is willing to pay for it in the stock market. A 3% dividend is worthless when your capital loss is 30%.

Does this stop me from engaging in the bigger fool theory for scalps?...no. We're all adults.

But it was always my choice until recently when the government and their crony's decided to place me in a long position without any stops...LOL...now it could crash & burn tomorrow and I wouldn't give a shit.

Of course, the problem is that much of America's effective savings and retirement are being gambled in the Wall Street casino where value is a function of greater foolishness and Fed POMO-induced confidence.  In other words, America's future is now a lottery ticket with poor odds of success. Don't quite get how economists model this in their "rational expectations hypothesis" cause what our nation is doing to itself seems about as irrational as you can get.  When the going gets tough and the liquidity provided by HFT disappears, then massive panic will set in with huge sell volume into non-existence bids across the board.  The crooners on CNBS will be left babbling like Thorazine-drugged mental patients utterly confused by the insane reality they helped to create and are then watching coming apart before their glossed-over eyes. All hope will seem lost, but there never was and never will be hope in temporal worldly wealth in the first place.  It's all just an illusion that misleads our faith.

It is definitely an illusion.

Politically, with a change in the House in the offing, the purse is snapping shut.

Psychologically, the gamblers are sitting around at the table eyeballing each other ready to call it a night.

Fundamentally, you cannot get out of debt by going deeper into it.

The system has always relied on trust backed by law. Both have been shattered (GM bond holder screwage, bank bailouts instead of bankruptcy, subprime to shatter hopes/dreams & finally their own weak credit, circumventing law in order to make law, using the dollar printing press to depress gold & silver at the behest of your own government etc.)

The reset cometh...plan accordingly.

If the casino is neutral, I'm down with it too, all good. The casino should make a market and the fed should stay the fuck out of it. Then it is psychology, supply, and demand, timing. Darwin can win the day. But if this is where Darwin is going to take us, well now!! Perhaps Darwin's long term answer for this shit is still building up.
