Exelixis Inc (EXEL)

For EXEL, some entity is manipulating the stock price. In my observation, they can make the price anything they want on any given day with low volume; less than 5,000,000 shares in the trading session.

They trade with about 125,000 - 200,000 shares multiple times each day. Also, I think they have two accounts to buy and sell shares. They would not necessarily need to be short to make a profit.

Typically, they run spreads of $0.10 - $0.25 amounting to $12,500 - $50,000 per day (34 days) or $425,000 - $1,700,000 per month. I haven't considered how to calculate what they are making from the Options contracts:
Cover Calls Sellers (Collected Premiums and Calls Expiring Worthless)
Puts Buyers (Paid Premiums and Puts Exercised at Settlement)
