Key takeaways

  • Meta did most of the damage in communication services.
  • Tesla and Amazon dragged the next sector fund down.
  • Nvidia called its buyback increase the largest on record.
  • Treasury yields closed at their highest since June 2007.

The fund that holds the large US phone, media and internet companies, XLC, fell 1.6% on Monday, the worst of the eleven sector funds. Meta, nearly a quarter of that fund, fell 4.8% and accounted for most of the drop.

The slide followed reports that OpenAI is expected to show a consumer assistant on Tuesday, one that would compete with Muse, the agent Meta launched this month. Meta had already fallen 3.3% on Friday. Over the week that ended that day, the stock was still up 13%.

Alphabet, about a fifth of the same fund, barely moved. Its two stocks in the fund fell 0.3% and 0.6%.

SPY, the fund that holds the S&P 500, fell 0.8%. Eight of the eleven sector funds finished lower.

Tesla, then technology

Consumer discretionary was the next worst. XLY, the fund that holds companies selling cars, travel and online shopping, fell 1.4%. Tesla fell 3.9% and Amazon fell 1.4%, and those two holdings accounted for most of that decline.

Technology fell even with its largest holding up. VGT, the fund that holds US technology companies, fell 0.8%.

Nvidia rose 1.7% after the company added $150 billion to the amount it can spend buying its own shares, taking the total still available to $235 billion. The company called that the largest buyback increase on record. Apple fell 0.8% and Microsoft fell 1.3%.

Yields at a June 2007 high, oil off its peak

The 10-year Treasury yield closed at 5.24%, the highest since June 2007. It was 5.18% on Friday and 5.11% on Wednesday. TLT, the fund that holds long-term US Treasurys, fell 0.9% and traded at a 52-week low.

Brent crude, the international oil price, traded as high as $108.81 and was at $105.72 late in the day, up 1.3%. The rise followed President Donald Trump's rejection on Saturday of Iran's proposal to reopen the Strait of Hormuz, the sea lane Iran has restricted since February.

It came off that high after a White House official said Trump is open to sanctions relief if Iran makes concrete progress on a nuclear deal, and after Saudi Arabia restarted a pipeline that had been shut earlier this month. US crude was up 0.7% at $93.08 late in the day.

XLE, the fund that holds large US energy companies, rose 0.1%. Exxon rose 1.2% and Chevron rose 0.9%, and losses elsewhere in the fund offset most of those gains.

Meta and Tesla pulled the two worst sector funds down. Nvidia's record buyback was not enough to keep technology up.
