$15 winds up suddenly at $2.
ARIA is not a perfect example since it took more than a day to reach into the 2's, but the overnight drop was expensive - from 18 to 6.
And those who got seriously damaged were the over-concentrated. Like me, though from the ARIA board it seems there were worse examples as a %age of portfolio.
