Can the Current Earnings Pace Translate Into Gains for VOO?

VOO (NYSEARCA:VOO) follows an index whose members are generating close to 30% third-quarter profit growth. At the Friday, October 23, 2026 checkpoint, blended growth measured 29.5%, compared with 29.2% both one week earlier and on September 30.

A different tally exceeded 32% from the prior year, putting the range near 29.5% to above 32% because providers use different estimate sets. Blended revenue growth reached 12.7%. Among companies already reporting, 66% topped sales forecasts, below the five-year norm of 70%.

Ten of 11 sectors recorded earnings expansion. The strongest contributions came from energy, technology, materials and communication-services businesses, while health care was the sole group in contraction. Even so, the index fell 0.52% to 7,623.68 Friday and about 0.5% for the week.

Why Have Frequent Earnings Beats Failed to Lift the Index?

At the October 23 checkpoint, 24% of constituents had announced results and 83% beat profit forecasts, above the five-year proportion of 78%. Yet the average surprise was 2.1%, far below the corresponding 7.5% norm, meaning much of the good news was already reflected in prices.

Valuation also changed. The forward 12-month price-to-earnings multiple was 18.7, compared with a five-year mean of 19.8, a 10-year mean of 19.1 and 19.0 on September 30. Profits have risen faster than prices, compressing the multiple.

Capital spending remains pivotal. Large cloud companies are expected to invest an annual amount near USD 800 billion, and investors increasingly question the cash returns from that outlay.

Which Concentration, Rate and Forecast Risks Could Disrupt the Week?

Reports are due from about 179 constituents, representing approximately one third of the index. Microsoft (NASDAQ:MSFT) reports Wednesday, October 28. Alphabet (NASDAQ:GOOGL) also announces that day, followed by Amazon.com (NASDAQ:AMZN) Thursday, October 29. Their index weights allow capital-budget guidance to affect the broader benchmark.

The Fed also decides October 28, with futures suggesting roughly a 71% to 80% probability of a December increase. Forecasts already assume fourth-quarter expansion of 29.2% and full-year 2026 growth of 33.1%, leaving little room for reductions.

October 29 brings third-quarter GDP and the September PCE inflation measure. Exxon Mobil (NYSE:XOM) reports Friday, October 30. Chevron (NYSE:CVX) is due the same day.

The reporting wave will test whether the unusually high aggregate rate is broad enough to support prices. Strong energy and technology results can lift the total even if other companies deliver smaller surprises. Investors will therefore compare the composition of growth with guidance rather than relying solely on the headline percentage.

What to Watch Next: Will October 28 to 30 Catalysts Validate VOO's Profit Outlook?

Profit growth near 29.5% to above 32% offers earnings support, but modest surprises and concern about AI spending have constrained the market response. The S&P 500 remains up approximately 11% during 2026 despite the latest weekly decline.

The Fed, Microsoft and Alphabet lead October 28, then GDP, PCE and Amazon arrive October 29 before the oil majors on October 30. Profit estimates are projections rather than promises. Nothing here is investment advice.
