Market Quants; Kill or Cure?

This brilliant VPRO documentary on Quants should be required viewing for all involved in markets.

The problem with heckling from the cheap seats is that the rest of the audience can get bored pretty quickly and stop listening. Then you get thrown out. It’s the old ‘cry wolf,’ thing. I kind of feel like that about shouting from my soapbox about quants and all they have spawned in markets from HFT’s, trading Algo’s, to derivative and structured product modelling. I’ve watched their growth from all the way back when index arb models lit the fire that turned into a market conflagration in 1987 to the subprime CDO models that did so much to destabalise the financial system in 08 through to the occasional flash crashes we see today.

The simple fact is that very few managers and certainly no boards have the first clue about what the quant ecosystem that plumbs their banks together is capable of. Nor do they understand the assumptions made in those models or how vulnerable the models are to human error or abuse, either internally or externally. The video clip above is very well worth watching. It is a very straight forward reality check; a reality check from the practitioners themselves; ‘it is clear that a major rethink is desperately required if the world is to avoid a mathematically led meltdown.’
