IMHO
If that trade was a purchase, it will very likely expire worthless.
Therefore I think those Calls were sold, not purchased.
I'll explain:
Just to break even, MU would have to go to a hair over $42.50 by next Friday. That is not likely to happen since the average increase in price that MU has shown over the last 18 months is about $0.36 per week.
Therefore, I think that trade was a Covered-Call sale (the kind of stuff I very often do). The seller thinks MU will stay relatively flat during the next week. If it continues to go down, after the current fall he is OK with that.
In fact the seller of those calls may have just purchased the shares today near the low today, which was $40.01. By selling those Calls his gain on that $40 is already a hair over 2.5%. If his shares are assigned next week at $41.50, then he has made an additional $1.48, or 3.7%, for a total gain of 6.2%. Not bad for a week's work.
