The Fed is continuing to add liquidity to the markets, and with light volumes it remains relatively easier to subsidize a soft lift to the market throughout the day.
Nice volatility for short term trading, but otherwise a treacherous market.
"Day by day the money-masters of America draw together, they grow more class-conscious, more aggressive. Political corruption was the buying up of legislatures and assemblies to keep them from doing the people's will and protecting the people's interests; it was the exploiter entrenching himself in power, it was financial autocracy undermining and destroying political democracy. By the blindness and greed of ruling classes the people have been plunged into infinite misery." Upton Sinclair
