Buyers are being cautious in the wake of the
shocking price swoon yesterday. Only 5k shares
were dumped, but there were no bids at that
moment. If we were on the NYSE, the specialist
would have contained the move by taking some
inventory until buyers came back. Now, buyers
will not extend beyond bids backing them up.
Sellers, on the other hand want the same prices
as they could get preswoon - hence the spread.
