• P/E ratio (47.8) — how many dollars you pay for each $1 of COST's yearly profit. That's high, so the market expects strong growth (and you're paying up for it).
• ROE (29.15%) — how efficiently the company turns shareholders' money into profit. Above ~20% is considered strong.
• Profit margin (3.01%) — of every $1 in sales, this is what's left as profit after all costs.
• Dividend yield (0.62%) — the cash payout you'd earn per year as a % of the share price, on top of any price gains.
