Stock market today: Dow, S&P 500, Nasdaq edge higher as Nvidia’s market cap hits $4T, Trump unveils more tariff letters

  • Starbucks (SBUX) stock jumped as much as 2% at the market open Wednesday after a report from CNBC suggested that the company has had multiple offers for its China business, including the likes of Centurium Capital, Hillhouse Capital, and US private equity firm Carlyle Group.
  • “We see significant long-term potential in China and are evaluating the best ways to capture the future growth opportunities,” a Starbucks spokesperson told Yahoo Finance. “We are looking for a strategic partner with like-minded values … and want to retain a meaningful stake in the business.”
  • The business there has struggled to compete with top rival Luckin Coffee’s low-price model. It has a store base of more than 20,000 stores, compared to Starbucks’ nearly 8,000 stores in the region.
  • Starbucks China’s same-store sales growth fell as much as 14% in both the third and fourth quarters last year before rebounding to flat in the latest quarterly results, thanks to a 4% increase in transactions that was offset by a 4% decline in the average ticket size.
  • A source told Yahoo Finance that lower prices announced last month have boosted sales in the afternoon and evening there, and zero-sugar options have increased the frequency of visits among customers. Analysts expect same-store sales to increase 2.49% for Starbucks China in its next quarterly report, per Bloomberg consensus estimates.

  • Copper imports have soared in recent weeks as the industry anticipated tariffs on imports. Industry insiders say the US currently brings in 50% of the copper it needs from abroad.

  • The S&P 500 and Dow were on pace to snap a two-day losing streak as markets have remained on edge following the unveiling of letters to US trading partners notifying them of tariffs starting on Aug. 1. Trump has said he will not extend that deadline and countries which have not reached a deal with Washington before that would need to start paying levies on imported goods coming into the US.
  • Nvidia (NVDA) stock gained another 0.6% in premarket trading Wednesday, building on its record closing price the prior day of $160.

  • Here are some of Wall Street’s early reactions:
  • Goldman Sachs’ Eoin Dinsmore
  • “Given the increased risk of a 50% tariff, we expect a further acceleration in shipments into the US in the coming weeks, as the incentive to front-run the tariff implementation has increased. With the Dec-25 COMEX-LME arbitrage now trading at ~$3,000/ton — pricing an implied ~30% tariff — we keep our long Dec-25 COMEX-LME arbitrage trade recommendation open. As we recently highlighted, there was a meaningful risk of a 50% tariff, which is now playing out. In time, the copper tariff may revert to 25%, but steel and aluminium tariff increased to 50% in June, and markets have priced around 80% of those tariffs, factoring in uncertainty on potential future exemptions – which suggests copper should move to price a 40% import tariff in Dec-25.”
  • Jefferies’ Christopher LaFemina
  • “Trump’s announced 50% tariffs on copper imports came as a surprise in terms of timing and magnitude, but tariffs were likely coming at some point. Higher copper prices in the US should ultimately incentivize growth investment in mines and new smelters/refineries. We believe the longer term aim of the Trump administration may be for the US to be fully self-sufficient in copper, but mines take too long to develop for this to be achieved in less than a 10-year time horizon, in our view. Getting there faster from a smelting/refining perspective is possible and would erode a competitive advantage that China currently has in the copper supply chain. However, as we discuss in this note, the US will still rely on foreign mines to meet demand for the foreseeable future. It is therefore possible that tariffs on refined copper imports will persist for a relatively long duration, which is what we have seen in the US steel industry following the roll-out of section 232 tariffs for steel by President Trump in 2018.”
  • Keep an eye on telecom stocks today, after some cautious comments out of KeyBanc.
  • T-Mobile US (TMUS) caught most of the ire of analyst Brandon Nispel in a downgrade to underperform.
  • “We think underperformance [in the stock] will continue for these reasons: 1) we think TMUS is fiber deficient in a converged/bundled world; 2) we think the near-term macro/competitive environment limits upside to expectations; 3) we think TMUS’s consumer value proposition has deteriorated due to recent pricing actions, which suggest TMUS shouldn’t take outsized share of the industry net adds; and 4) we think TMUS will relatively benefit the least from tax changes due to the One Big Beautiful Bill,” Nispel said.
  • Nispel maintained sector-weights on shares of Verizon (VZ) and T-Mobile, but voiced concern about rising competitive activity holding back financial results this year.
  • Here’s what T-Mobile CEO Mike Sievert recently told me on industry phone-plan prices.
