This Is What Happens When An HFT Algo Goes Totally Berserk And Serves Knight Capital With The Bill

We all know something went horribly wrong in various NYSE-traded stocks today between 9:30 am and 10:15 am. So wrong in fact that the NYSE had to step in and cancel numerous trades in 6 symbols. However it did not DK millions of other trades in 134 other symbols, the vast majority of which we assume traded errantly due to the market making of Knight Capital (as admitted by the company), which today saw its biggest drop ever since going public on volume about 60 times greater than its average. We also all know that one should buy low and sell high. At least that is what human traders are taught, and that is what they attempt. Because if one consistently does the opposite, one will simply run out of money. Well, the opposite is precisely what the berserk algo in Knight's Market Making group may have done if Nanex, which has done a forensic analysis of one of the trades in question, is correct. In other words, instead of at least attempting to provide liquidity via limit trades, Knight's algorithm acted as a market order... gone horribly wrong. As the third chart below shows what the algo did with furious repetition and steadfast consistency was to buy at the offer, and sell at the bid, in other words buy high and sell low. Over and over and over and over. As Nanex laconically notes, "In the case of EXC, that means losing about 15 cents on every pair of trades. Do that 40 times a second, 2400 times a minute, and you now have a system that's very efficient at burning money." Which also means that by not DK'ing several hundred million prints, the NYSE may have just thrown Knight under the bus, because the market maker is suddenly on the hook for tens if not hundreds of millions in inverse market making profits.

Mar del Plata y yo

lo dijo Sabina refiriendose a Madrid


Yo Me Bajo En Atocha
Joaquin Sabina

Con Su Boina Calada, Con Sus Guantes De Seda,
Su Sirena Varada, Sus Fiestas De Guardar,
Su Vuelva Usted Mañana, Su Salvese Quien Pueda,.
Su Partidita De Mus, Su Fulanita De Tal.
Con Su Todo Es Ahora, Con Su Nada Es Eterno,
Con Su Rap Y Su Chotis, Con Su Okupa Y Su Skin,
Aunque Muera El Verano Y Tenga Prisa El Invierno
La Primavera Sabe Que La Espero En Madrid.
Con Su Otoño Velázquez, Con Su Torre Picasso,
Su Santo Y Su Torero, Su Atleti, Su Borbón,
Sus Gordas De Botero, Sus Hoteles De Paso,
Su Taleguito De Hash, Sus Abuelitos Al Sol.
Con Su Hoguera De Nieve, Su Verbena Y Su Duelo,
Su Dieciocho De Julio, Su Catorce De Abril.
A Mitad De Camino Entre El Infierno Y El Cielo...
Yo Me Bajo En Atocha, Yo Me Quedo En Madrid.
Aunque La Noche Delire Como Un Pájaro En Llamas,
Aunque No Dé A La Gloria La Puerta De Alcalá,
Aunque La Maja Desnuda Cobre Quince Y La Cama,
Aunque La Maja Vestida No Se Deje Besar,
"pasarelas Cibeles", Cárcel De Yeserías,
Puente De Los Franceses, Tascas De Chamberí,
Ya No Sueña Aquel Niño Que Soñó Que Escribía,
Corazón De María, No Me Dejes Así...
Corte De Los Milagros, Virgen De La Almudena,
Chabolas De Uralita, Palacio De Cristal,
Con Su "no Pasarán" Con Sus "vivan Las Caenas",
Su Cementerio Civil, Su Banda Municipal.
He Llorado En Venecia,
Me He Perdido En Manhattan,
He Crecido En La Habana, He Sido Un Paria En París,
México Me Atormenta, Buenos Aires Me Mata,
Pero Siempre Hay Un Tren
Que Desemboca En Madrid.
Pero Siempre Hay Un Niño Que Envejece En Madrid,
Pero Siempre Hay Un Coche Que Derrapa En Madrid,
Pero Siempre Hay Un Fuego
Que Se Enciende En Madrid,
Pero Siempre Hay Un Barco Que Naufraga En Madrid,
Pero Siempre Hay Un Sueño
Que Despierta En Madrid,
Pero Siempre Hay Un Vuelo De Regreso A Madrid.

Inglaterra y las cometas

No, no las de papel, hasta hace poco, como en varios lugares, las comentas que pagaban para engrasar negocios era deducibles de impuestos, y bueno, business are business, pero el primer parrafo con la doble moral es imperdible,

Analysis We used to draw a distinct line between what was acceptable business conduct here at home and what we did abroad with Johnny Foreigner.

Inviting Bertie from your major customer to Henley or the Derby, or waving Cup Final and Olympic tickets in his face was entirely acceptable. Slipping him £500 for an order was bribery and both illegal and immoral.

But what you did abroad was an entirely different matter: bribery was until very recently tax deductible.

The Bribery Act has rather changed this. There's still considerable confusion as to whether, if Bertie is a public servant, you can actually take him on corporate away-days worth thousands. You can most certainly buy him a pint and have no problems, but as with so many new laws this has been written so loosely that many are still a little unsure of where the boundary lies.
Those people selling expensive corporate Olympics packages have complained that this very uncertainty has led to a large fall in demand. If a few thousand quid to take a favoured customer to the, say, men's 100 metres finals can be looked upon as a bribe then who is going to risk jail for that?
Given that we are in the opening stages of the season for corporate jollies it probably is worth having a discreet word with a lawyer who knows - just to be on the safe side.
This is of course very different from the system of old. Which was, essentially, that soft soaping someone with experiences and days out was just absolutely fine while any mention at all of cash was not just legally but also socially verboten.
At home, in Britain, that was. Having worked in some pretty odd and even rough places I've done my share of bribing people, but even so I would be profoundly shocked if I was asked for a bung in Blighty. But the system also most definitely facilitated the payment of bribes to Johnny Foreigner.

Nokia

Nokia fue un ejemplo de muchos, de maderera a fabricante de celulares, etc el libre mercado etc.pero, el libre mercado se la deglutio, mal, bien, cada uno tendra su opinion, eso si a algunos finlandeses mucho no les gusta.

Impending shutdown has severe impact on Salo

“This is where it all began, but hopefully it will not end, at least with respect to product development”, says Aimo Leskelä, who has been the shop steward of product development at the Nokia factory in Salo for the past 20 years.
      “Shutting down production at the Salo factory has a great symbolic significance for residents of Salo as well as for Finns”, Leskelä says.
      He says that his mobile phone was ringing non-stop on Wednesday evening.
     
Most of the employees walking out of the main gate of the factory refused to say anything to journalists standing there with microphones extended.
      In the afternoon, engineer Jani Tuomela rode out of the main gate on his bicycle.
      “It is unfortunate that Nokia is leaving Salo. It is here that the first telephones were assembled.”
     
Tuomela, who has worked in product development since 2003, does not make any predictions on what will happen to R&D. However, he is optimistic about his own future.
      “There will always be work for people who do things.”
      Leskelä says that it now seems that all 1,800 product development employees will keep their jobs in Salo. However, the job cuts that have been announced are set to raise unemployment in Salo to about 20 per cent.
     
Project worker Pirjo Batalha is not bitter as she walks into the factory area.
      “I have been at work here for more than 20 years and I have always been loyal and grateful for my job.”
      “This isn’t Nokia’s fault – it’s about the situation on the world market. It could just as well have been any other company”, Batalha says.

Efecto Dunning-Kruger

El efecto Dunning-Kruger es un fenómeno psicológico según el cual las personas con escaso conocimiento tienden sistemáticamente a pensar que saben mucho más de lo que saben y a considerarse más inteligentes que otras personas más preparadas, debido a que su propia incompetencia les dificulta reconocer sus errores y evaluar la competencia de los demás.
El fenómeno fue demostrado en una serie de experimentos realizados por Justin Kruger y David Dunning, de la Universidad de Cornell (Nueva York, EE. UU.). Sus resultados fueron publicados en el Journal of Personality and Social Psychology de diciembre de 1999.¹
Kruger y Dunning investigaron cierto número de estudios previos que tendían a sugerir que en diversas habilidades como la comprensión lectora, conducción de vehículos de motor, y juegos como el ajedrez o el tenis, “la ignorancia frecuentemente proporciona más confianza que el conocimiento” (como dijo Charles Darwin). Su hipótesis es que, en una habilidad típica que los humanos poseen en mayor o menor grado,

1. Los individuos incompetentes tienden a sobreestimar su propia habilidad.
2. Los individuos incompetentes son incapaces de reconocer la habilidad de otros.
3. Los individuos incompetentes son incapaces de reconocer su extrema insuficiencia.
4. Si pueden ser entrenados para mejorar sustancialmente su propio nivel de habilidad, estos individuos pueden reconocer y aceptar su falta de habilidades previa.
