With EA earnings next week and the stock currently going down, it may be prudent to consider adjusting a naked short position. The 52-week high is $60.63, the high of Oct 2007 was $61.62, and the all-time high of March 2005 was $71.16. If it breaks above the current 52-week high, and with such strong momentum behind it, who knows how far it keeps going. I'm suggesting either purchase calls around $61 to limit short exposure, or swap short shares for puts around that price.
