Anthony - just want to make sure you know -- NASDAQ volume figures, in addition to being (roughly) double vs. the way the NYSE or AMEX would report the same sequence of trades (because with NASDAQ, the buying securities firm and the selling securities firm BOTH input the trade (or, something like that)), there is also the problem that volume reporting is just plain sloppy and wrong.

Several times in my long (and stupid(?)) trading career, I personally have transacted a big piece of an extremely thinly traded NASDAQ stock, and then seen the volume reported for that day as less than my trade (and occasionally -- zero shares).

If this double counting problem still applies (and, the short interest figures are actually correct) (another big question mark ...), then the short interest figures are even more impressive (than before you read this).

Jon.
