Amazon earnings helped lift US stocks at week’s close, even as Nasdaq logged its worst month in more than a year

US equity markets ended the week higher as investors leaned into optimism from Amazon’s latest earnings, according to Yahoo Finance. While the broader tone improved into the close, the Nasdaq Composite still marked a notable underperformance for the month, described as its worst stretch in more than a year.

A key macro headwind remained interest rates. The 10-year Treasury yield topped 4.7% on the day, reaching its highest point since January 2025, a move that tends to put pressure on growth-oriented stocks by raising the discount rate used to value future earnings.

The week’s price action reflected a tug-of-war between individual company momentum and the cost-of-capital backdrop. In that mix, Amazon’s reported earnings were singled out as a sentiment driver, suggesting that at least some investors were willing to look past the rate shock and reward results they viewed as durable.

The same market wrap highlighted other high-profile names in focus, indicating that investors were not only tracking broad index moves but also parsing company-specific updates for clues on demand, margins, and spending. The takeaway from the post was that stock selection mattered as much as the index narrative.

Amazon is a bellwether for both cloud and retail demand. Its earnings are watched closely because performance can announcement spending intentions across enterprise customers for AWS, as well as consumer and advertising trends in its retail and media businesses.

Separately, the reference to Nasdaq’s worst month in more than a year underscores how sensitive the technology-heavy index has been to interest-rate expectations. Even when the week finishes green, the cumulative effect of prior sessions can remain dominant for investors assessing valuations and risk appetite.

Still, the market report did not provide granular figures in the excerpt available here, such as exact index point changes, how much Amazon stock moved on the day, or the specific earnings line items investors focused on. It also did not disclose which rate-related catalysts were driving the 10-year yield intraday, beyond noting the level reached.

Looking ahead, investors are likely to watch whether the 10-year yield stabilizes after its move above 4.7% and whether Amazon’s earnings-driven sentiment can translate into broader follow-through for rate-sensitive growth stocks. The next test will be whether late-week gains hold into the next session as traders reassess valuation risk in a higher-yield environment.
