Another good article:

Heavily Shorted VS Normal Market Bid/Ask
machinations

I will try to briefly respond to your question about
the bid/ask machinations in the market. I am by no
means an expert and have simply learned out of
necessity to understand basically what is going on
sometimes. I will discuss a typical market (part I);
and a heavily-shorted one (part II).

Part I - Typical Bid/Ask Pricing of The Stock

If you had level II you would know right away what
I have been talking about in past posts because it
shows what is really going on in a particular
stock's marketplace resulting in the bid/ask you
see on the screen (level I). A simple way to explain
it is the stock's price is kind of like a see-saw; one
seat buy, one seat sell. If the weight is more
heavily on the buy side the price goes up, chasing
the supply-demand curve up to the notch where
the weight is more evenly distributed on the
see-saw. The converse happens when the weight
is more heavily on the sell side.

Level II actually shows how all the bids and asks
are queuing up to each seat on the see-saw,
including the id of who (which MM's) are
responsible for the weight distribution. As I
understand it the bid/ask reported on level I are the
sustainable bid and ask prices. That is why on
quote.com, for example, they report the bid
(sustainable) and the best bid. And also, that's
why you can have sales that are outside of the
bid/ask range and yet see the bid ask remain the
same before during and after that sale. Quote.com
is worth watching for awhile to understand what I
am talking about. It turns yellow with each sale
showing which side of the bid ask the negotiated
sale was made. (If you click on the data area it
reveals the bid ask info. I talk about.)

In what I call a normally-motivated market it is
easier to understand how stock prices are set. I
mean basically, in NASDAQ, the several mm's are
trying to make a market and are competing for the
client buyers/sellers' business. They establish and
live off the spread between the buy and the sell. A
bigger buyer or seller will try out different MM's and
to succeed in keeping their business they need to
make sales and buys to keep their customers
happy.

NASDAQ relies on the competition between
MM's to self-regulate market action. In other
words, in a competitive market the different MM's
competing for the business will keep each other
honest. Apparently there are also rules about their
behavior. Thus, on level II you can see the different
MM's trying to make a market on a stock, each
one's current bid and ask, and also the current
demand associated with the position. These guys
make sales and purchases back and forth which
we commonly see (in level I) as the general market
in the stock.

Thus, if several MM's have customers that want
to buy the stock; more than want to sell, then they
raise their bid price (their want ads) because that
will probably get more sell offers by walking up the
demand-supply curve. If they have several clients
that want to sell, more than want to buy, then they
lower their offer (their for sale signs) to interest
more buyers. Its a pretty efficient system, and the
different MM's negotiate with each other pretty
quickly, and can move large volumes of shares as
the price moves up and down the supply demand
curve.

Now, all the above is more complicated than
described above and MM's can establish different
spreads, can take out stop-loss orders by moving
the price rapidly - particularly in lightly traded
markets; and can move the market in the manner
and timing of their buys and sells. But I won't get
into any more detail; there are plenty of books with
all the gory details.

It gets more interesting when the shorting of
shares is introduced into the above mix.

Part II - Buying/selling in shorted markets

When a market is heavily shorted like tdfx (2.6
M shorted shares in 10M float market), what is
"normal" bid/ask behavior gets altered (influenced)
by the changed motivations of the trading
participants. Now there still may be be numerous
(short-covering) buyers, but to get the business
they put out lots of "want ads" that show a buying
interest but only at a lowering price than what is
being offered.

Thus, you will often see a sale at the bid price
and then the bid will be lowered, as if the only
people wanting to buy this dog are less and less
willing to give up good money for it. Sales at the
offer price, or at a negotiated in between the
bid/offer price become rarer, but when made the
bid price is often lowered. This is because the
purchaser's (shorter's) primary motivation is to buy
shares, yes, but at the lowest price the can get
them at.

What also happens is that these
"differently-motivated" MM's will have a stockpile of
the stock and they will sell these shares to each
other (back and forth) at the bid price or lower. In
this way they can actually create a falling market,
that results in a lowering price, frees up sellers
willing to duck out, and of course gets them their
covering shares at lower prices.

Eventually, if they dry up the pool of shareholders
willing to sell, they allow the price to rise a bit (by
staying off the bid for a while) and then lower the
boom again (shaking the tree); or simply keep
pounding the stock down using the 2 basic
techniques above to free up more scared sellers.
Of course, if shareholders refused to sell or called
in their certificates the short positions would be in
deep do-do. But that rarely happens because of
the lack of organization among shareholders. (It
takes less effort to sell or sit back and blame the
company, than to actually do something and try
and organize with other investors.)

All the above works best in a lightly-traded
market, where there is believable doubt that can be
created about the prospects of the underlying
company, where good news can be contested, and
where big buyers are unlikely to jump in and be a
"fly in the ointment" of the above
carefully-orchestrated trading activities.

In sum, look for buying at the bid, light trading,
the size of the short position, consistent downward
price walking behavior, shaking of the tree price
behavior, etc. You know, look for a lot of the things
we have been seeing on this stock over the last
3-4 months. This indeed has been a good learning
experience for me. I plan on using my lessons to
make a lot more money in the future with the
knowledge gained.

The only reason I have continually banged away
at trading behavior as the cause of the price fall is
because all the board discussions were looking for
the cause of the fall in numerous places outside of
the market. My main point remains that this
short-term price fall is most likely (and largely)
trader-induced.
