4. SPX WEEKLY OPTIONS — GROSS PREMIUMS OF MORE THAN 50% PER YEAR?
A 12-page paper by Russell Investments entitled “Capturing the Volatility Premium through Call Overwriting” (December 2010) (available at www.cboe.com/benchmarks) explored the BXM Index and other SPX systematic call overwriting strategies, and noted that:
“ … Exhibit 6 compares the 15-year historical annual premiums received by rolling weekly, monthly, quarterly, and annual ATM options. This historical data shows that shorter term options maximize the total amount of premium received on an annual basis. A one week tenor option rolled four times per month has generated more than 2.0x the premium of a one month tenor option rolled once per month. … This helps make clear that close to the money strategies with short tenors have consistently generated a higher level of gross income. … That said, it is important to note that short tenor strategies increase the probability of capping the upside in any given period. This is the result of the increased probability of paying an exercise cost when these shorter dated ATM options expire in-the-money. …”
Here a couple of cautionary notes re: gross premiums for a strategy of selling Weeklys covered call options:
(a) The transaction costs for selling Weeklys options every week of the year could be significant;
(b) The net returns from a covered call strategy could be negative, and usually are less than the gross premium received. (For a comparison regarding SPX monthly gross premiums received for the BXM Index, please see Exhibit 13 of the paper by Hewitt EnnisKnupp entitled “The CBOE S&P 500 BuyWrite Index (BXM) – A Review of Performance” (2012) (available at www.cboe.com/benchmarks)).
