Year-End Tax Planning: October 2026 Market Commentary on Prices and Yields

Market Snapshot — October 2026

Source: S&P Dow Jones Indices (S&P 500, Dow Jones Industrial Average), Nasdaq, Inc. (Nasdaq Composite), U.S. Department of the Treasury, Federal Reserve, Bureau of Labor Statistics — October 14, 2026. Index month change is measured from the September 11 close to the October 14 close, matching the prior snapshot date. Consumer Price Index and Core CPI (which leaves out food and energy) are the 12-month changes through September, released October 14. Unemployment is the September rate. Nonfarm payrolls is the September change in jobs. The federal funds target range is as of the snapshot date.

What Is Core CPI?

Core CPI is a measure of consumer prices that leaves out food and energy. Food and energy prices are very volatile, which is why economists widely use this measure. Headline CPI, by contrast, includes food and energy, which is why the two rates can differ.

The Month in Two Sentences

Consumer prices rose at a faster annual pace in September, the 10-year Treasury yield moved to 5.19% on October 14, and between September 11 and October 14 the major equity indices diverged, with the Dow Jones Industrial Average lower and the Nasdaq Composite higher. For households working on year-end tax planning, that mix reinforces the importance of coordinating gains, losses, conversions and gifts around a calendar that does not move with the market.

The Current Environment

Equity indices diverged between the two snapshot dates. Measured from the September 11 close to the October 14 close, the Nasdaq Composite rose 1.37% and the S&P 500 rose 0.81%, while the Dow Jones Industrial Average moved down 1.81%. The three indices hold different companies, so they can move apart in the same month. After the snapshot, the Nasdaq Composite moved lower. It closed at 25,955.34 on October 23, which is 2.76% below its October 14 close. CNBC reported on October 23 that fears surrounding artificial intelligence spending and higher oil prices hit stocks that week.

In fixed income, yields moved higher between the two snapshot dates. On the snapshot date the 10-year Treasury stood at 5.19% and the 2-year at 4.82%, compared with 4.96% and 4.63% on September 11. Treasury’s daily yield curve then shows the 10-year at 4.96% on October 22 and 5.00% on October 23, a move BlackRock Investment Institute described as Treasuries rallying while investors sought safety from the technology selloff. Higher yields can raise the interest paid on cash and on newly purchased bonds, while the market price of fixed-rate bonds already held generally falls when interest rates rise. The IRS says most interest received is taxable income in the year it becomes available to the taxpayer.

Inflation data remains elevated. Consumer prices rose 3.7% over the twelve months through September, up from 3.4% in August, in the report released October 14. Excluding food and energy, prices rose 2.6% over the same twelve months. Bureau of Labor Statistics data show that gasoline prices rose 9.1% in September alone and that the energy index rose 5.2%, and BlackRock Investment Institute refers to a Middle East energy shock. The unemployment rate rose to 4.2% from 4.1%, and employers added 29,000 jobs in September, according to the Bureau of Labor Statistics.

On September 16 the Federal Open Market Committee raised the target range for the federal funds rate by a quarter point to 3.75–4.00%, on a 12–0 vote. The statement said that “Inflation remains elevated.” The range in the snapshot is the range in effect on October 14. On October 28, after the date of this snapshot, the Committee decided to maintain the target range at 3.75–4.00%, on a 10–2 vote. The two members who voted against preferred to raise the target range by a quarter point. The October 28 statement again said that “Inflation remains elevated.” That decision is not folded back into the snapshot.

For a household finishing a 2026 tax plan, the market moves the amount of each decision but not the date on which it counts. A stock sale made on or before December 31 generally belongs to 2026 by its trade date. A Roth conversion completed by December 31 generally belongs to the 2026 return. For a traditional IRA owner, the required minimum distribution for each year after the first is due by December 31 (IRS Publication 590-B). Index levels and yields can change between now and then. Those dates do not.

Planning Implications

• A small move in an index can sit on top of large differences between holdings. The S&P 500 changed by 0.81% over the period, while a household’s own positions can sit well above or well below their purchase prices, so which positions carry gains or losses for 2026 is a question about the household’s accounts, not the index.
• Because an index can rise while individual positions fall, a household can hold realized or unrealized losses in a month like this one. A realized loss first offsets capital gains, then up to $3,000 of other income (IRS Topic 409), and any remainder carries to later years. The wash-sale rule can disallow the loss if substantially identical securities are bought within 30 days before or after the sale, including in an IRA the seller owns.
• Higher yields can raise the interest that cash and newly purchased bonds produce, and that interest generally counts as income in the year it is received. It goes on the same return that carries any gain or conversion for the year.
• A Roth conversion adds its taxable amount to the year it is completed, cannot be reversed after it is made, and cannot include the required minimum distribution of an IRA owner who owes one for the year. The market on the day of a conversion changes its amount, not the year it lands in.

Discipline

In a month like this one, households that decided in advance what would make them act have less to decide now. The goal of year-end tax planning is not finding every possible deduction before December 31 — it is coordinating gains, losses, conversions and gifts into one return. Prices can keep changing through December. The year-end calendar does not.
