# Energy and Semiconductors Surge; Indices Post Broad Gains on September 13

**The broad market moved higher across all three major indices on Sunday, with energy stocks leading a pronounced sector rotation that pushed integrated oil companies up 17.4% in equal-weight terms.** The Nasdaq Composite, S&P 500, and Dow Jones each posted gains between 0.86% and 0.98%, while the Russell 2000 trailed slightly at +0.45%, suggesting that large-cap strength drove the day's momentum.

The energy sector's rally was particularly striking. Integrated oil companies—including Chevron, ConocoPhillips, and Valero Energy—posted an average gain of 17.4% across eight holdings, the strongest performance of any sector tracked. Coal mining stocks similarly surged, with five companies in the space averaging +10.4%, reflecting what appears to be a broader rotation into traditional energy. Electronics distribution and durable goods also posted double-digit average returns, though these were concentrated in just one or two holdings each (notably Alliance Entertainment, which itself jumped 16.5%).

On the flip side, rental and leasing companies posted the steepest sector decline, falling 15.3% on average across four holdings including Ryder System, Avis Budget Group, and U-Haul. Wholesale distributors dropped 18.1%, and blank-check companies—special purpose acquisition vehicles—were slammed with a 36.5% average loss, though that sample was only two companies. The tobacco sector also weakened, with a 17.1% retreat in that single-company bucket.

Individual stock moves were volatile. ACV Auctions surged 44.2%, while Frequency Electronics gained 42.4%—both exceptional moves that likely reflected company-specific news not detailed in today's data. Hewlett Packard Enterprise was among the day's stronger performers, up 12.4%, alongside smaller gainers in semiconductors (Vicor, +11.2%) and biotech (Mereo BioPharma and Relmada Therapeutics, both in the 11-14% range). On the downside, CPI Card Group fell 16.5%, Telos dropped 15.6%, and Sellas Life Sciences declined 14.4%—again, moves that warrant checking for company announcements or sector headwinds beyond today's broad energy rally.

Several firms recently filed their fiscal 2026 annual reports (10-K filings), including Palo Alto Networks (Health Score 40.2), Intuit (56.9), and Zscaler (21.7). Of note, Zscaler's 10-K filing came shortly after its September 3 date, and its Health Score of 21.7 is notably low—a reminder that filing an annual report does not guarantee financial stability. Five other companies currently carry going-concern warnings in their auditor notes: Entrada Therapeutics, FS KKR Capital, Bain Capital Specialty Finance, New Mountain Finance, and Innovative Industrial Properties. Going-concern flags suggest material uncertainty about a company's ability to continue as an operating entity and deserve close scrutiny from any investor holding or considering these names.

The day's broad advance in large-cap indices belies significant dispersion underneath, with energy rebounding sharply while some cyclical sectors (rental, wholesale) retreated. For value-focused investors using Money Checkup's screener, today's volatility underscores the importance of reviewing individual Health Scores and financial fundamentals—sector-wide moves can mask wide variations in company health.
