Quote from ess1096:
You would only pay 15% on 60% of any profits regardless of how long you hold it. The 60/40 rule applies to all futures and index options.
If you trade index options, or other non-equity options such as on bonds, commodities or currencies, the results of a sale are treated differently.
For example, options on the SPX, OEX, and NDX are not directly or indirectly related to a specific equity (stock), but are exchange-traded options of index stocks. These are subject to the provisions of IRS Code Section 1256, which states that any gains or losses from the sale of these securities are subject to the 60/40 rule (60% of gains and losses are long-term and 40% are short-term, regardless of how long the securities are held). Non-equity options are usually reported on IRS Form 6781 (Gains and Losses from Section 1256 Contracts and Straddles).
There have been many conflicting opinions as to whether QQQQ, DIA, and SPY options should be treated as section 1256 contracts or not. Since these do not settle in cash, as do most section 1256 contracts, some suggest that these are not section 1256 contracts. Others feel that they meet the definition a a "broad-based" index option and therefore can be treated as section 1256 contracts.
