The current company emerged in 2019 when DowDuPont separated into three parts, leaving the materials science business that Herbert Dow started in Midland, Michigan in 1897. Commodity chemicals are made from natural gas and naphtha feedstocks and sold into packaging, construction, and consumer markets, so margins are the spread between energy input and product price. North American shale gas gives domestic plants a cost advantage over European and Asian competitors. Capacity additions across the industry drive multi-year price cycles. Headquarters are in Midland, Michigan.

If a meaningful share of your net worth sits in DOW, 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 DOW's option-implied volatility.
Example: 5,000 DOW shares at $31.19 is a $155,950 position. A 30% drawdown costs $46,785; a 50% drawdown costs $77,975; a 70% drawdown costs $109,165. The calculator quantifies the trade-off between selling down (immediate capital-gains tax) and hedging (option premium drag) using DOW's option-implied volatility and your cost basis.

Dow equity questions
- How much DOW stock is too much?
- There is no single threshold, but the larger the share of your net worth in one stock, the more a single bad year can set back your plans. The calculator above quantifies the drawdown impact at 30, 50, and 70 percent for your DOW position and weighs selling down (which triggers capital-gains tax now) against hedging (which costs option premium).
- Does Dow grant ISOs, NSOs, or RSUs?
- Equity compensation at Dow typically takes the form of restricted stock units (RSUs). Restricted stock units are taxed as ordinary income when they vest.
