The off-price retailer buys excess inventory from brands and department stores and sells it in no-frills stores at discounts, a model that depends on merchandise availability rather than merchandise planning. Buyers purchase opportunistically and close to season, so the supply chain runs on flexibility instead of forecasting. Low store operating costs and minimal advertising support the price gap. Retail disruption elsewhere improves the supply of discounted goods. Headquarters are in Dublin, California.

If a meaningful share of your net worth sits in ROST, concentration risk is the question. This calculator quantifies drawdown impact at 30 / 50 / 70%, and the trade-off between selling down (tax cost now) versus hedging (option premium drag), auto-filled with ROST's option-implied volatility.
Example: 5,000 ROST shares at $236.38 is a $1,181,900 position. A 30% drawdown costs $354,570; a 50% drawdown costs $590,950; a 70% drawdown costs $827,330.
