70% of volume is wash trades by quants. or High frequency trading frontrunning client orders. 70% of revenue for SEC and exchange is from HFT operations and the operators of the HFT are the broker/dealers like who's earningsi is 20% from prop trading or HFT trading their own accounts. so why would the SEC or exchange limit o ban HFT? serious money know this and know there is nothing worthy of investing in equities. in equities you need at least 5% dividend or at least 10% to worth owning these stocks. there is nothing to worthy of investing. and what is wrong with t-bills and bonds if there is no inflation or growth. stocks can lose like 50% in price adn stocks can go to zero. you might was well buy bonds if the dividend is only 2% is the USD becoming worthless? and the FED main goal is to protect the value of the currency not by by printing money and giving the printed money to fat cats in wall street. quantative easing is printing money from thin air. oil is $80/barrel what deflation. all these mutual fund managers like legg mason bill miller who gets paid millions for doing nothign who make 3% management in managing paper to buy stocks is another reason to dump stocks.
