What moves each company

Company-specific drivers maintained by Yield Theory. Use them to decide which filing deserves deeper work; they are not predictions.

What moves DOV

We have not yet published a company-specific driver list for DOV. The primary source is Item 1 (Business) and Item 1A (Risk Factors) of its 10-K filed 2026-02-13.

What moves NSC

  • Freight volumes across intermodal, coal, industrial, and agricultural traffic
  • Operating-ratio trajectory and precision-scheduled-railroading efficiency efforts
  • Safety and remediation costs stemming from the 2023 East Palestine derailment
  • Pricing power relative to long-haul trucking competition

The investment question

You now know NSC reports about 1.5× DOV's revenue, and NSC keeps more of each dollar as net income. Those are the facts. The investment question is what each share price already assumes about their exposure to economic trends, including “Freight volumes across intermodal, coal, industrial, and agricultural traffic” at NSC, and which evidence in the next filings would prove that assumption wrong.

SEC filing comparison and disclosure evidence

Start with primary filings because fiscal calendars and accounting presentation can make superficially similar quarters incomparable. Both fiscal years end December 31, so annual reports line up, but check segment definitions before comparing growth or margins.

The current verified House and Senate snapshot contains 8 matched transaction rows for DOV and 18 matched transaction rows for NSC. These delayed, range-based disclosures can identify a filing to inspect; they do not establish motive, conviction, or a real-time trading signal.

What this comparison cannot tell you

This page does not contain licensed live prices, a valuation model, earnings estimates, portfolio constraints, or a forecast of future returns. SEC classifications can be broad, company descriptions can lag strategic change, and the latest annual filing may predate a material acquisition or divestiture. Read subsequent quarterly and current reports before making a decision.

A stronger business is not automatically the better stock. Starting valuation, expectations, capital structure, cyclicality, dilution, and the probability of each thesis determine the investment outcome. Use this comparison to frame the work, then verify the numbers in the linked filings and current company disclosures.
