From one of your links:
Put simply, the quants have ruined our markets by exaggerating short-term price moves...
This seems true.
High-volume program trades for a few pennies/share up or down do distort the markets.
Many of these moves are the result of a FED member or other notable saying the right (or wrong) thing.
Or because some reported value came in "higher (or lower) than expected."
I'm just a dumb guy reading the internet but it's obvious that these days the fundamentals of a given stock, industry or commodity are farther down the list of value criteria than they used to be.

This seems true.While that sure sounds good, for months now
we've simply not had any "exaggerating short-term price moves".
imho the only reason he can get away w/ saying that there was is becuase most readers just love to blame workers in the finance sector for all kinds of problems --real and imagined.
