Dendreon (DNDN) saw much options activity, but that would be expected because of the FDA panel review.  There were some fortunes made and lost on this one.  Of the top 15 options contracts in total trading volume Friday, 10 of the various strike and expiration months of DNDN were there.  This one was so aqctive after the reopen and subsequent 92.5 million shares that it masked some of the other usual options screens.

Brocade (BRCD) saw 22,150 contracts trade in the APR07 $9 Puts.  With the stock still close to its year highs someone is either hedging for 2.2 million shares or they are making a leveraged bet that the good news won’t last.

Traders have some pretty large long-term bets that Vista will be a winner for Microsoft (MSFT) as the open interest in the JAN08 $30 CALLS 337,000 contracts. That represents 33.7 million shares on a fully leveraged basis.  The open interest in the JAN08 PUTS is pretty high as well: $27.50 142,580 contracts; $25.00 156,273 contracts; $22.50 101,299 contracts; and $20.00 222,258 contracts.

Ford (F) has quite a few hedgers and speculators in the options as well.  Out of the 20 largest open interest contracts, 6 of the 20 belong to Ford.

True Religion (TRLG) had much higher than normal options activity as the stock traded 4-times normal volume on buyout rumors.  The company has been a potential “buyout name” for some time, but oddly enough the street wasn’t impresses with its last earnings.  There is also a split in the design area as the CEO and VP of women’s design are calling it splitsville.  Acquiring this company better include the full design team that has made it such a success story since this was as low as under $1.00 in 2004 and now sits at $16.24.

This one may not be the Most Unusual, but BJ Services (BJS) saw 5,648 contracts trade in the JULY07 $30 CALLS.  The open interest in the near-month APRIL07 contracts is more than 50,000 contracts if you combine the $27.50, $30.00, and $32.50 CALLS.  There is still speculation of more mergers being considered in the drillers and service companies in oil and gas, so who knows on this one.

Halliburton (HAL) still has some strange open interest in ARIL07 $40 PUTS/CALLS and it is possible these were either left from the KBR or a trade based on the self-tender.  It is listed as more than 430,000 contracts in each.  With the stock at $31.74 this may have been a large capture trade based on the old KBR spin-out or on the self tender.

Oddly enough, Sirius Satellite Radio (SIRI) is seeing less and less options trading and the LEAPS are much more vacant in open interest than one would guess for such a widely followed and speculated upon stock.  Its merger partner XM Satellite Radio (XMSR) is seeing the same thing.  That is a bit baffling for such a widely followed merger and for such a controversial situation.  The short interest was mostly steady in SIRI in March (123.6M vs. 125.1M in FEB) and grew in XMSR saw its short interest grow (31.2M vs. 28.9M in FEB).  Go figure.
