Grade F Stocks

Buyback-driven negative equity: Companies like Apple (before it was graded) or Starbucks may have negative shareholder equity from massive buybacks. This triggers balance sheet checks but is actually a sign of financial strength.

Serial acquirers: Companies that grow through M&A (like Broadcom, Honeywell) will have high goodwill, high leverage, and large intangible assets. The acquisition strategy is deliberate, not a red flag.

Utilities and REITs: Capital-intensive businesses with high debt are structurally leveraged. Debt/EBITDA checks trigger by design.

High-growth SaaS: Companies investing heavily in growth may have negative FCF, high accruals, and rising SG&A ratios — all features of their growth model, not earnings manipulation.

Convertible debt artifacts: Some companies (like Datadog, Zscaler) have convertible notes that create accounting distortions in cash flow statements.
