Two years after the Flash Crash – Spreads are Narrower and Liquidity Deeper than Ever Before? Guess Again.
21I bought 500 shares of IBM on the opening print today. You would think 500 shares would be pretty easy to liquidate within a penny or two considering how our market scholars claim that the market has deeper liquidity and tighter spreads than ever before. Anyways, a minute after the open, this is the quote that I was trying to liquidate that 500 shares into:

Yes that’s right you are reading the quote correctly. The spread was 37 cents. 100 shares x 100 shares. Looks pretty thick and deep to me. And why does the quote change so many times in the one second increment that I have shown? HFT liquidity providers change their quotes continuously in that 1 second increment, usually trying to aggressively penny each other, but then cancelling their orders simultaneously.
So if I wanted to sell my 500 shares at the market, I could be filled on one hundred shares at 203.10, and pay that 37 cent spread. And on the last 400 shares, who knows where I would be filled.
But this is just an isolated quote isn’t it? Guess again. Here is the quote two minutes later. It’s actually a penny wider, 38 cents.
But it does gets better, and the spread does tighten up. 11 minutes into the trading day the spread is now a tight 27 cents.
Well IBM is a $200 stock so of course the spread is going to be wider. This isn’t the case with other DOW components is it? No they are indeed tighter.
Proctor & Gamble (PG) had a nice tight spread of 21 cents, 19 seconds after the open.
Coke (KO) had an 11 cent spread, in the first 30 seconds of trade.
Then tightened to a 10 cent spread, 100 shares x 100 shares 2 minutes after the open.
MMM had a cool 25 cents spread after the open.
These are supposed to be some of the most liquid stocks on our exchanges. Where is all this liquidity that our academic scholars claim the market has?
Well if you analyze spreads in the middle of the day, you will get an entirely different picture.
If you bring up the IBM quote in the middle of the day, you will typically find the spread to be only a few cents. Coke and P&G will usually have a 1 cent spread Why is this? HFT liquidity providers do not like risk, and when there is so much uncertainty of where the price is going (like when the stocks open, or right before market moving events), they simply do not quote aggressively. Many HFT programs don’t quote at all.
Nanex showed images of the E-mini liquidity around a 10:00 economic number release on April 19th. http://www.nanex.net/aqck/3233.html They call it a liquidity vacuum, as HFT participants cancel their orders ahead of the number.
Was this lack of liquidity an isolated event today? Hardly. This is a daily occurrence. I would challenge all our academic scholars who analyze spreads to take a good look at liquidity a few minutes after the open, or around any type of market impact event such as a 10:00 economic news release. You’ll find liquidity to be very thin and very dispersed. Indeed, we have plenty of liquidity in the market, just not during periods of market uncertainty.
Update: We’d like to thank Nanex for taking the time to post liquidity charts of the stocks mentioned in this article:

Relevance of Gaps
0On our premarket show this morning we highlighted a gap area in the chart of AVP, and the potential for that gap area to be filled.
Understanding Imbalances
0If you were watching the IBM tape late in the day, the stock started to sell-off significantly around 3:45 ET, and then gapped down on the closing print to close at $202.72. What happened?
Your answer is a large sell imbalance was posted by the NYSE at 3:45 pm ET. These sell imbalances are published every day at this time, and sometimes they can have a major influence on the price of the stock.
The designated market maker (DMM) on the floor of the NYSE continuously logs all the buy MOC (market on close) orders, and all the sell MOC orders, on their security. And then at 3:45 PM ET, this information is disseminated to the market. (It is a good idea to check with your data provider, to make sure they carry the imbalance feed).
Large buy imbalances will typically press the stock higher, where large sell imbalances will typically press the stock lower.
In the IBM example, traders subscribing to the imbalance feed, seen the sell imbalance at 3:45, and then began selling the stock, with the expectation that the closing MOC sell orders would press the stock lower. It worked perfectly in the case of IBM today, as the stock gapped down on the closing print.
It is not always that simple however. In this HFT world, many algorithmic systems will manipulate these closing imbalances, and sometimes in the last minute or two they will flip, causing a sell imbalance to go to a buy imbalance. If that happens it catches many imbalance traders by surprise.
Sometimes these imbalance plays get crowded as well. And if too many imbalance players are on the same side of the trade, the imbalance could also flip.
In any regard, funny things happen after 3:45 in NYSE issues, and if you don’t subscribe to the imbalance feeds, you might be missing some pretty important information.
End of the Quarter Window Dressing
0Today is the end of the quarter. Considering that we have had one of the best quarters in years, it would not be surprising to see the market close strong this afternoon. Why is that?…two simple words, “window dressing”. What exactly does that mean? To put it simply, it means that portfolio managers typically report their holdings to their investors at the end of the quarter. And what better way to impress your investors, then to hold stocks that have been performing very well. In other words, portfolio managers tend to “dress-up” their portfolios, by buying the quarter’s outperformers, and selling the laggards.
Therefore, stocks that have had a good quarter, often have a good couple of days at the end of the quarter as fund managers accumulate positions in those issues. For example, take Coke (KO), it has had crazy buy imbalances at the end of the close the last two days, probably due to some institutional investors trying to accumulate stock. It very well may have a large buy imbalance again today for the same reason, this would press a stock like KO higher into the close. Overall, since the entire quarter has been very strong, there could be some significant accumulation in a number of issues at the end of the day today.
These gains are typically short lived, as these stocks will often give back their gains in the following week or two. In any regard, if stocks do rally into the close, it may be a good idea to lighten up on some of your longs.
What happened in Coke?
0Coca-cola (KO) spiked up 90 cents right near the end of the close today, but then quickly fell back down. What happened? A crazy buy imbalance is your answer.
