If you need options on the S&P 500 the CBOE’s SPX series is one of the most popular solutions in the marketplace. The CBOE continues to enhance this product with additional expirations—the latest being the addition of options expiring on Monday afternoons. It’s just a matter of time before they add another weekday—my guess is that Tuesdays will be next.
In May 2017 the CBOE did some welcome cleanup on the SPX options. Previously the weekly SPX options that expired on the same Friday as the monthly SPX option series carried the SPXPM ticker. The SPX and SPXPM options differed in that the SPX options expire at open on those Fridays and the SPXPM expired after market close. Other than expiring on the same day as the SPX options the SPXPM options were no different than the SPXW options expiring on other Fridays. Not surprisingly this difference created problems. Since the SPXPM options didn’t show up in most SPX option chains most people didn’t even know that they existed. In addition, most brokers’ software did not recognize that the SPXPMs were effectively SPXWs so if you tried to use them in a calendar spread with other SPX/SPXW options you were out of luck. The CBOE has rationalized this situation by renaming the SPXPM as SPXW options which in hindsight was the right symbology all along.
- 10X the size of SPY options, reducing commission costs if you are trading positions of that size. Their price is roughly 10X the equivalent SPY option. If the SPX options are too large for you the CBOE also offers XSP contracts which are approximately the same notional size as SPX options. XSP options have same characteristics as SPX options but tend to have wider spreads and not as much liquidity.
- Considered taxable as section 1256 contracts—generally 60% of your gains are treated as long term, regardless of how long you hold them
- Cash settled so there is no need to close out a trade just to eliminate the risk of an option being exercised, or expiring in the money and triggering a buy or sell of the security.
- They eliminate pin risk, and any other scenarios where you end up long or short securities when your options expire in the money
- They can only be exercised at expiration (European style), so there is no risk of early assignment unbalancing a spread position. You don’t have worry about ex-dividend dates triggering assignments.
- For SPXW options there are no delays in settlement—the settlement price of SPX (ticker SET) can sometimes be delayed an hour or more because order imbalances delay trading on some stocks, the market close is inherently more orderly.
- SPXW options are easier to trade into expiration because you don’t have the overnight risk associated with the AM expiring SPX options. You don’t have to worry about the market gapping up or down before market open—insteady you have the relatively more predictable market close dynamics to work with.
- There are six flavors of SPX options:
- The standard AM settled options that expire on the morning of the third Friday of the month (SPX). These are floor traded and tend to have relatively wide bid/ask spreads. Their expiration value is published under the ticker SET (^SET for Yahoo Finance).
- Firve PM settled flavors: the Monday (new), Wednesday and Friday Weeklies, the End of Month, the Quarterlys, and the PM version of the SPX (SPXPM) that settles Friday afternoon on the Fridays where the AM settled options expire also. The first five show up under the SPX option chain, but their ticker is SPXW. The Quarterlies will trump the Weeklys and the End of Month if they all fall in the same week. The PM expiring options use the standard S&P 500 Friday close SPX (^GSPC for Yahoo Finance) as their expiration value.
- If you want Friday PM settlement on the traditional monthly expiration week you must use the SPXW symbol not the SPX symbol—user beware.
- The minimum increment on prices, even spreads is $0.05
- Close to the money strikes are offered at 5 point intervals (e.g., 1795 / 1800), the equivalent on SPY options would be 179.5 / 180. These 5 point intervals enable tight credit / debit spreads and better resolution in placing positions.
- The bid / ask spreads on AM settled SPX options tend to be wide, the PM settled options are somewhat better. For SPX options, a limit order halfway between the bid and ask will usually fill. Never use a market order—you are leaving money on the table. This is one area where SPY options are superior.
- Non-expiring SPX/SPXW options trade 15 minutes after the regular market close
- Even when AM expiring SPX options have expired, some broker’s software (e.g. Schwab and Fidelity) will not consider them closed until the following Monday. This is problematic if you have a calendar option position in place with the expired options as the short leg. A work around for this in order to effectively close out your long position is to roll it up to a much higher strike. This requires some margin, but at least you can effectively cover your position.
Trading SPX options in IRA accounts can have some wrinkles. Schwab doesn’t support cash settled index options like SPX spreads in IRA accounts, their software doesn’t support it. Fidelity and OptionsXpress support vertical spreads, but Optionsxpress doesn’t allow calendar spreads.
