The last time my inbox was bombarded with emails of such monotony was during the heyday of credit derivatives. At the time I said that the credit derivatives models were stupid but unfortunately I hadn't fully realized the size of the market, and therefore the potential for systemic risk. The state of my inbox should have warned me.
Now I know better. So according to my inbox there is far too much algo/hf/computerized trading. The minimal benefits this confers in terms of supposed "efficiencies" is far outweighed by the potential it has for causing chaos. Penny wise, pound foolish.
