The Russell 2000 closed Tuesday, September 15, 2026, at 2,870.29, down 21.95 points or 0.76%. Its opening value of 2,890.64 was also the reported session high, making the subsequent distance from the opening level the clearest feature of this small-cap close.

The initial gap was just 1.60 points, about 0.06% below Monday’s close. By the finish, the benchmark stood 20.35 points beneath the open. On rounded figures, approximately 93% of the full daily decline was the open-to-close difference, rather than the small deficit present at the opening.
The 28.91-point high-to-low range represented approximately 1.00% of Monday’s closing value. The final reading was 8.56 points above the low, placing it in the bottom 30% of the range. Opening at the reported high does not imply that prices fell continuously; a daily bar cannot reconstruct every intervening move.
Tuesday’s high was 1.60 points below the previous close, so the index’s reported range never crossed into a gain against Monday. The final value was also 15.25 points below Monday’s low of 2,885.54. Together, these comparisons show weakness extending beyond a single closing-point calculation.
FTSE Russell’s official index-family description identifies the Russell 2000 as its U.S. small-cap benchmark. This report concerns the cash index, not an ETF share price or a futures settlement. It does not attribute the decline to a particular industry, borrowing-cost channel, or constituent without supporting contribution data.
The September 15–16 Federal Reserve meeting is the next scheduled policy reference. Its outcome remains separate from this completed session.
