ARQL CC

1 minute before the market closed, another one of my orders got filled - I sold an April '08 ARQL covered call (strike - 5) for 0.15. It was funny because I had just raised my price from 0.1 to 0.15 and it got filled very soon after. I'm not sure what to do with ARQL. Including this covered call, I've had a return of 16% since 2/21. But I have no long term interest.
