Foreign geek quants have backlash. Excellent article highlights of this part 2

Some things foreigners doing quant jobs should be aware of. This was another interesting article posted at Quantnet.com. Here are some highlights you should be aware of:

I was recently observing an online discussion with the author of a book about high frequency trading. The writer defended a point by stating, “ have you never heard of Brownian motion as a model for diffusion of asset prices? Longer horizons are always less certain than the shorter ones.” This is not a statement about markets. This is a statement about a particular model (a number of situations are more certain in the long run). To be completely fair, the author could have been referring to a feature of the model, but the statement easily leads the reader to infer otherwise. Such blurring of the distinction between models and reality is far too common.
