In a pivotal week for tariffs, how Apple shined and drove the Nasdaq to new highs

The stock market experienced a strong rebound this week, with the S&P 500 gaining 2.4% and the Nasdaq advancing 3.9% to a new record closing high. Apple significantly contributed to the rally, surging over 13% after pledging an additional $100 billion in U.S. investment, which secured a tariff exemption from President Trump amid broader tariff concerns, including new levies on India and potential pharmaceutical tariffs. Conversely, Eli Lilly shares plummeted nearly 18% due to disappointing clinical trial results overshadowing strong earnings. Overall, the Q2 earnings season has been robust, with 81% of S&P 500 companies reporting sales and earnings beats, exceeding 10-year averages.

Analysis

The U.S. equity market demonstrated notable strength this week, with the S&P 500 gaining 2.4% and the Nasdaq climbing 3.9% to a new record high, underpinned by a robust second-quarter earnings season and significant company-specific developments. According to FactSet, 81% of S&P 500 companies have reported upside surprises for both sales and earnings, exceeding 10-year averages and providing a solid fundamental backdrop. Apple (AAPL) was a principal driver of the rally, surging over 13% after securing an exemption from U.S. semiconductor tariffs by committing an additional $100 billion to domestic investment. However, AAPL shares remain down over 8% year-to-date, and now face potential supply chain risk from a new 25% U.S. tariff increase on India, where it manufactures iPhones for the U.S. market. Thematic risks from trade policy also broadened, with the administration signaling potential tariffs on pharmaceuticals. This backdrop exacerbated pressure on the healthcare sector, exemplified by Eli Lilly (LLY), which plummeted nearly 18%—its worst week since 2008—as disappointing Phase 3 obesity drug trial data overshadowed strong earnings. The market's reaction to earnings was highly nuanced across other names: DuPont (DD) saw a muted sub-1% gain despite a beat-and-raise quarter, while Eaton (ETN) and Disney (DIS) fell approximately 4.9% and 3.5% respectively, despite positive earnings reports, as investors focused on weaker forward guidance or mixed top-line results. Conversely, Coterra Energy (CTRA) faced headwinds from weak commodity prices despite strong production, and Texas Roadhouse (TXRH) saw its stock fall 5.5% as strong sales were offset by margin compression from elevated beef prices.

Key Decisions for Investors

• Consider the de-risking of Apple (AAPL) following its tariff exemption, but closely monitor for clarification on its AI strategy and any supply-chain disruptions arising from new tariffs on India.
• Be selective in the current market, as strong earnings beats are not guaranteeing positive stock performance, evidenced by the negative reactions for Eaton (ETN) and Disney (DIS) due to guidance concerns.
• Exercise caution in the pharmaceutical sector, which faces dual headwinds from potential new tariffs and significant downside risk from clinical trial outcomes, as demonstrated by the severe decline in Eli Lilly (LLY) shares.
• Evaluate potential opportunities in companies like DuPont (DD), where strong fundamental performance and positive guidance were not fully reflected in the stock's modest weekly gain.
• For commodity-exposed stocks like Coterra Energy (CTRA), recognize that strong operational execution may be insufficient to offset the negative impact of weak underlying commodity prices.
