Not to be confused with nas100, dxy, stock index.

US30 is a trading symbol used by many brokers for the Dow Jones Industrial Average, an index of 30 major U.S. companies. The symbol itself is not a standardised instrument: it may refer to a cash index, a futures contract or a broker-created derivative, and the exact composition and weighting are set by the index provider, not the broker. Because the underlying index is price-weighted, higher-priced stocks move the index more than lower-priced ones.^[1]

What the symbol represents

US30 is a marketing label rather than an official ticker. The official ticker for the Dow Jones Industrial Average is DJI on many data feeds, while futures may trade under YM. A broker offering US30 may be quoting a cash index, a rolling futures position or a synthetic product, and the contract specifications, trading hours and settlement method vary by broker and jurisdiction.

Because the index is price-weighted, a $100 move in a high-priced component affects the index more than a $100 move in a low-priced component. The divisor used to calculate the index is adjusted for stock splits and changes in composition, so the index level is not simply the sum of its components' prices.

Worked example

A trader buys one US30 contract at 35,000 with a broker that quotes the index in points and charges a spread of 2 points. The index rises to 35,150 and the trader closes the position.

US30 long trade

Entry price35,000—

Exit price35,150—

Gross points35,150 − 35,000150

Spread cost2 points−2

Net points150 − 2148

The monetary value of 148 points depends on the contract size and the currency of the account, which are set by the broker. A different broker may quote a different spread or use a different contract size, so the cash result is not comparable across platforms.

Trading hours and settlement

Trading hours for US30 vary by broker and product. Cash index CFDs often follow the underlying exchange's regular session plus extended hours, while futures-based products may trade nearly around the clock on weekdays. Daily financing charges, dividend adjustments and expiry rules also differ. These details are specified in the broker's contract specifications and are not universal.

Often confused with
