Poor Fab, but it could be worse. Michael Lewis has a heartbreaking, enraging story in Vanity Fair about poor Sergey Aleynikov, the former Goldman programmer and current Dostoyevskyan holy fool who was sentenced to federal prison for eight years for stealing computer code from Goldman, won a complete victory on appeal, was released, has lost his life savings, and is now being prosecuted under state law just because Goldman, or someone, but probably Goldman, really hates him. It is troubling stuff not least for Lewis’s clear implication that a jury trial may not be the best way to arrive at the truth regarding complex financial-technological questions. E.g.: Read more »
The Financial Times has an article today called “Greece reaches agreement with ‘troika’ on bailout tranche” and I’m not going to tell you about it but you can go read it if you want. If you’re an FT subscriber just click on this link and there you are. If not, maybe try typing that title into Google and clicking on the first result you get; that’ll probably work, no guarantees.

That’s the way a lot of news works: if you have an internet connection and a desire to get it, you probably can, but if for idiosyncratic reasons you want to get it quickly and reliably – say, you invest in Greek debt and need to know what’s going on for trading purposes – the way to do that is to pay for it.

One problem that people with a lot of time on their hands like to get worked up about is that academic economists sometimes write papers advocating positions that benefit organizations that give them money, while being coy about that relationship. On the other hand this newish paper about dark pools, which compete for stock trading orders with exchanges like NYSE and Nasdaq, has a first author whose affiliation is listed as “The NASDAQ OMX Group, Inc.,” so that’s fine then. Guess what he thinks? No, kidding, you don’t get to guess, he thinks dark pools are bad, duh.
The study, by Dr. Frank Hatheway, Nasdaq OMX Group; Dr. Hui Zheng, the University of Sydney; and Dr. Amy Kwan, the University of New South Wales, looks at US trading venues with restricted access and without displayed orders – generically referred to as “dark pools” – which increasingly segment order flow in the US. … The authors show that the effects of order segmentation by dark venues are damaging overall price discovery and market quality.
I’m a sucker for market microstructure papers because I like the Hobbesian world they imagine, where everyone is trying to rip everyone else’s face off, and keep their own face on, every nanosecond. Read more »
