XBI Analysis

SPDR S&P Biotech (ETF) (XBI)

Update 7/17/2017: XBI has traced a sideways pattern since I entered the position. Although options expiration is a month away, I exited to make room in my account for earnings plays, which tend to be higher velocity and more profitable. I exited at 12.3% of maximum potential profit, about half of my 25% target.

Shares rose by 0.5% over 12 days, or a 15% annual rate. Tye options position produced a 14.0% yield on debit for a +426% annual rate.


XBI has sufficiently high implied volatility relative to its most recent and annual ranges to qualify as a direction-neutral trade.

I shall use options that trade for the last time 44 days hence, on Aug. 18.

Implied volatility stands at 30%, which is 2.5 times the VIX, a measure of the volatility of the S&P 500 index.

XBI’s IV stands in the 27th percentile of its annual range and the 91st percentile of its most recent broad movement.

The price used for analysis was $78.27.
