While the sell off was faster than those in the past, it is not unexpected with the sharp rise in program trading.
Bull markets routinely bounce back to make dazzling new highs after corrections of 10-20%. Each time when in a deep correction the bewildered herd becomes bearish.
Markets always the herd wrong at the big turns. Less than half of the declines of up to 20% lead into a bear market, only time will tell.
Because I am a nimble trader it does not matter to me which direction the market goes in as long as it is not flatline for very long.
This time it is different.
