Screener snapshot — prices as of 2026-08-28. Each side's last close is the most recent session the snapshot holds for that company, which can be an earlier one, and its 1-year return is measured to that close. Market caps struck on 2026-08-27. Last close, market cap and the 1-year return are price figures; every other row is computed over the company's latest filed fiscal year, and the two differ: NTAP FY2026 (ended 2026-04-24); WDC FY2025 (ended 2025-06-27). A return on equity past ±100% — NTAP at 106.7% — divides earnings by an average filed equity base smaller in magnitude than the earnings themselves; the two columns are not on one scale.
