While we already presented, courtesy of Nanex, the modus operandi of the Knight berserker algo, there was one outstanding question. What was the bottom line. And no, not how much the loss on Knight’s Income Statement would be as a result of this glimpse into what really happens in the market: we already knew that would be $440 million. The question is what is the notional amount of stock that this algo bought in the 45 minutes in which it was operational. We now know: $7 billion. Or $155 million per minute. Or $2.6 million per second. Or, assuming the algo impacted just 150 stocks as previously reported, it was buying on average $17,333 in each name every second. Or, assuming an average stock price of the universe of 150 stocks of $30/share, the Knight algo lifted the offer roughly 600 times each second. For 45 minutes straight! That’s right – the market making algorithm of a designated market maker which is responsible for 10% of the order flow in the US stock market, entered a pre-programmed mode (because the computer was told to do whatever it did by someone, and not without reason) that saw it buy up $2.6 million worth of stock every second.
Now there has long been speculation that HFTs are a central planner’s best friend because they traditionally provide not only a floor to the stock market, but a gradual levitation bias especially in a low volume environment (as well as liquidity its advocates claim, but that is total BS – HFT only provides volume and churn – liquidity disappears at the drop of a bat when real selling pressure appears). They do this not because they are evil instruments of Bernanke collusion (although who knows) but simply because they accelerate and accentuate legacy momentum bias, which at least historically, has been up. Now in the aftermath of the Knight debacle we can also extrapolate what would happen if, say, reality were to creep in one day, and all those mutual and hedge funds which have carbon-based life forms making the buy and sell decisions suddenly decided to sell. Well, at $7 billion in 45 minutes, or 1/10th of the trading day, this means that had the Knight algo been running all day, it could have bought $70 billion worth of stock. Throw in the remaining flow routers, aka DMMs in the market which account for the remaining 90% of order flow, and we get a total of $700 billion in vacuum tube mediated purchasing power.
In other words, this is the market “worst case” shock absorber, or inverse escape velocity, that Bernanke has at his disposal if things turn sour. That said, with hedge funds, aka fast money, holding about $3 trillion in unlevered assets, and about $6-9 trillion with leverage (ignoring plain vanilla slow mutual funds), and one can see why not even the HFT levitation bid would be sufficient to offset a wholesale market dump.
There is one last open question remaining on Knight: what discount did Goldman extract out of the firm to rid it of its residual position which as the WSj explains declined slightly from its peak as “traders worked frantically Aug. 1 to sell shares while trying to minimize losses due to a software problem, ultimately paring the total position to about $4.6 billion by the end of the trading day” (one wonders if the market would have just blown up if the Knight algo were to run in reverse, and just take out layer after layer of bids to unwind the inventory asap). We now know thanks to the WSJ:
Knight avoided that scenario by agreeing in the early morning hours last Thursday to sell the portfolio to Goldman Sachs Group Inc., after rejecting an offer from UBS.
The terms sought by the banks reflected how dire Knight’s situation was: UBS wanted an 8% to 9% discount on the position, according to people familiar with the matter.
The equities trading desk at UBS, headed by Mike Stewart, bid for the portfolio around 6:30 p.m. Wednesday, people familiar with the discussions said. Mr. Stewart was a former colleague of Knight Chief Executive Thomas Joyce’s at Merrill Lynch. The talks with UBS fell apart later that night.
Goldman ultimately negotiated buying the portfolio at a 5% discount, or about $230 million less than the value of the stocks, the people said. That amount, not previously reported, represents more than half the loss Knight disclosed on Thursday that it incurred as a result of the technology errors.
The deal with Goldman allowed Knight to move ahead. Last weekend, Knight negotiated a rescue package with six financial firms that injected $400 million in capital in exchange for securities that can convert to ownership of 73% of the trading firm.
And now you know why having cash on your balance sheet in a ZIRP environment may well be the best investment, because just like Goldman, one never knows just where a slam dunk distressed opportunity could come from in exchange for an immediate 5% pick up.
More importantly, the Goldman deal demonstrates what the true liquidity cost in the market is when one wishes to do a wholesale stock transaction (either BWIC or OWIC): it is not less than 5% and tops out at 9%.
Keep that in mind, because if and when the day when VWAPing in and out of positions is no longer possible, each and every fund will have no choice but to assume a guaranteed 5% minimum (up to 9%) haircut on one’s entire portfolio of allegedly liquid stocks.
We dread to think what the wholesale implied liquidity premium is on less liquid products than stocks, which nowadays is virtually everything…

Finally, we leave readers with yet another transformative animation from Nanex, after our first rendition of the “rise of the machines” back in February left many speechless, and which recently appears to have been rediscovered by some of the slower elements in the blogosphere. Why: because it’s pretty, and we feel like it. And because it once again confirms that only vacuum tubes with infinite balance sheets should be gambling in this loaded market.
