The Forgotten "Flash Crash" -- One Year later

``Regulators say a large seller of E-Mini futures and a large purchase of put options on the S&P-500 Index by a hedge fund set off a chain of events that triggered the "Flash Crash." High frequency traders sold aggressively to liquidate their positions and quickly withdrew from the markets to avoid the meltdown, once the Crash began. The combined actions of these events sent the Dow Jones Industrials plunging -7% in just 15-minutes. Yet for seven days, prior to the historic "Flash Crash," bullish equity traders had plenty of time to exit from over-extended long positions, but didn't, because the small and obscure credit default swap market for Greece's debt, wasn't even on their radar screens.''
