What to look at in Technology companies
- Revenue growth 3y (>=15%/year) — Validates sustained traction, not a one-off.
- Gross margin (Sub-sector dependent) — SaaS >=70%, Internet >=55%, Semis >=45%, Hardware >=35%.
- FCF / Revenue (>=20%) — Real cash generated. Many tech firms dress up non-GAAP earnings.
- ROIC (>=15%) — Capital reinvested efficiency — Buffett's first metric.
- SBC / Revenue (<10% healthy) — Stock-based compensation. Silent dilution: >20% destroys value.
- Net Debt / EBITDA (<=2x (1.5x SaaS)) — Resilience in downturns and rate hikes.
