the dow is at 6,500 after shedding 4% today. how low do people think it will go? as a side note, after shedding 89% of its value from 1929 to 1932, the dow did not recover its pre-crash volume peak until 1968. any guesses on how many counts it'll take before the market gets up and starts punching again?
