S&P 500 Holds Near Peak as Breadth Lags Before the Open

At the close on Friday, September 18, major U.S. equity indexes delivered mixed results, reflecting divergent performance across sectors. The S&P 500 closed +0.1%, with SPY finishing at $761.69. Large-cap technology shares provided upside support, helping the Nasdaq 100 close +0.6%. In contrast, traditional industrial and smaller companies lagged, as the Dow closed -0.2% and the Russell 2000 small caps finished -0.5%. Underlying market participation remained narrow: only 34.1% of the largest U.S. companies advanced during the session. Following that close, the market sits -2.1% from its all-time high.

While New York was shut, EasyAlpha re-graded every company in the S&P 500 against its industry peers. Our latest scoring run upgraded several companies: Eaton Corporation PLC (ETN) D to B on the sentiment around it, 3M Company (MMM) C to B on the sentiment around it, and Howmet Aerospace Inc (HWM) C to B on the sentiment around it. These adjustments reflect changes in our own assessment of each company relative to its peer group. In each of these cases, the upgrade was driven by positive shifts in the sentiment surrounding the business.

Conversely, our evaluation lowered grades for other prominent index members: Healthpeak Properties Inc (DOC) A to C on the sentiment around it, Qualcomm Incorporated (QCOM) B to E on its price behaviour, and Nucor Corp (NUE) B to E on the sentiment around it. These downgrades stem from our own measurements rather than any external event happening to the companies. EasyAlpha grades evaluate companies strictly against competitors in the same industry. Companies graded A or B have stronger fundamentals, and historically they have carried a lower risk of large drawdowns than companies graded D or E.

In continuous overnight trading while New York was shut, global commodity and currency benchmarks posted minor adjustments. As of 10:35 am New York, silver +1.0%, the yen against the dollar -0.2%, the pound against the dollar -0.1%, and gold -0.1%.

Looking ahead to the session on Monday, September 21, corporate earnings announcements are light to start the week. A total of 2 covered companies are scheduled to release results today, marking the beginning of a week where 28 companies across our coverage report quarterly figures over the coming week. The companies reporting today without a specified release time are Apartment Investment and Management Co (AIV, graded E), US Gold Corp (USAU, graded C).

Several individual stocks enter today's session with active storylines. In technology acquisitions, Qualcomm Incorporated (QCOM) completed its acquisition of Modular Inc. for approximately $3.1 billion. In corporate capital moves, RB Global Inc. (RBA) enters the open after doubling its share repurchase authorization to $1 billion. Meanwhile, Carpenter Technology Corporation (CRS) enters the session following a quiet move on Friday amid broader market pressure from rising bond yields, with our sources showing no reported company announcements behind the price action.

Several companies that experienced sharp price swings in the prior session remain in focus today. On the upside, Coinbase Global Inc (COIN) +11.7% surged as Bitcoin climbed back above $80,000, while Sandisk Corp (SNDK) +11.0% gained ahead of its scheduled entry into the S&P 100. On the downside, Nucor Corp (NUE) -6.3% fell sharply after providing third-quarter earnings guidance that trailed analyst projections, while Qualcomm Incorporated (QCOM) -5.8% also finished among the session's steepest decliners.

Understanding why foreign exchange fluctuations matter to an investor holding only domestic U.S. shares begins with the global footprint of modern corporations. In overnight markets, currencies such as the yen and the pound adjusted against the dollar. An investor who only owns American stocks might assume currency fluctuations are irrelevant to their portfolio. However, exchange rates directly influence corporate revenues and profit margins across the S&P 500.

A large proportion of total sales for major U.S. companies comes from customers located overseas. When an American business sells semiconductors, industrial parts, or consumer products in international markets, those transactions are priced in foreign currencies like euros, pounds, or yen. When reporting quarterly results to U.S. investors, the company must translate those foreign revenues back into U.S. dollars. When the dollar strengthens, each unit of foreign currency translates into fewer U.S. dollars, which lowers reported revenue and compresses operating margins. Conversely, when foreign currencies strengthen against the dollar, overseas revenues translate into more dollars, boosting reported earnings even if unit sales remain flat. Currency shifts also impact product competitiveness, as a stronger dollar makes American exports more expensive for overseas buyers. Even for an investor who never trades foreign exchange or buys international stocks, currency movements reach straight into the financial statements of domestic holdings.
