XBI Trade

SPDR S&P Biotech ETF (XBI)

Update 5/13/2021: I exited my bear call spread position on XBI 36 days before expiration, for a $0.50 debit per contract/share, a profit before fees of $102 per contract. Shares were trading at $120.40, down $5.19 from the entry level.

My decision to exit was based on the profit exceeding 50% of its maximum potential, an exit point that is mandated by my rules for trading options spreads.

Shares declined by 4.1% over seven days for a -216% annual rate. The options position produced a 97.6% return for a 5,319% annual rate.

I’ve updated the chart below.

I have entered a short bear call spread on XBI, using options that trade for the last time 43 days hence, on June 18. The premium is a $1.01 credit per contract share and the stock at the time of entry was priced at $125.59.

The implied volatility rank (IVR) stands at 49.2%.

Premium: $1.01 Expire OTM  
XBI-bear call spread Strike Odds Delta
Long 140.00 85.0% 18
Break-even 133.99 80.5% 23
Short 135.00 76.0% 28

The premium is 40.4% of the width of the position’s wing.
The profit zone covers a 6.7% move to the upside, with no limit to the downside.

The risk/reward ratio is 4:1, with maximum risk of $399 and maximum reward of $101 per contract.

Elliott wave analysis. XBI hit a peak of February 9 of $174.79 and began a downtrend that is now in its 3rd wave. I set the short call at $135, which is $9.41 above the entry price. The 3rd wave, typically the strongest in a trend, began on March 16 from $149.24. Upon its completion, the 3rd wave will begin a 4th wave correction. Fourth waves tend to be shallow, sideways-trending movements, and so my theory is that any correction will remain well below the $135 short-call strike.
