Debt = borrowings plus lease liabilities. Cash & securities = cash, equivalents and short-term marketable securities (long-term securities are not counted, so net cash can be understated for companies like Apple). Net debt = debt minus cash & securities. Source: latest SEC 10-Q/10-K. EBIT / EV yield = operating profit divided by market cap plus net debt.
Fair value estimate
$247model spread $235 – $259
Fair +5.1% to fair value
Equal blend of three models: peer multiples, a fundamentals-adjusted multiple (growth, ROIC and margin) and a 10-year DCF scaled to the market's average. Earnings-power value (no growth) is a floor and not part of the blend. Model uncertainty is Medium, so the safety margin is 30%.

Oscillators use the usual thresholds (RSI 30/70, Stochastic 20/80, CCI ±100, Williams %R −80/−20; MACD and momentum above zero are bullish). Weekly and monthly views use closing prices only.
