Once the dust settles who to blame for the market meltdown. SEC are already working on this......hmmm lets see we could ban short selling....nah...ban short selling unless on uptick nah tried that....ban automated electronic trading....yes that's the answer we are going back to phone>broker>market maker>exchange. Also ban leverage no margin allowed. All buys/sells will need to be completed with actual stock certificates. Don't laugh all wonderful new regulations come from disasters, including financial disasters.
