Nasdaq Announces End-of-Month Open Short Interest Positions in Nasdaq Stocks as of Settlement Date June 30, 2026

Nasdaq released its routine end-of-month short interest report for June 30, 2026, a standard regulatory disclosure with minimal market-moving implications. The data shows 3,804 Nasdaq Global Market securities with aggregate short positions totaling 18.45 billion shares, representing a modest 3.1% increase from the prior settlement date of June 15, 2026.

The uptick in absolute short share count was accompanied by a notable compression in short interest days-to-cover, declining from 2.79 days to 2.45 days. This metric compression indicates that while market participants increased gross short exposure, the velocity of covering accelerated—suggesting shorts are holding positions with tighter conviction or liquidity conditions shifted favorably. The data spans 3,804 securities versus 3,764 in the prior period, indicating modest new listings or classification changes.

From a structural perspective, the 2.45-day cover ratio remains historically conservative by modern standards, reflecting healthy liquidity in the Nasdaq ecosystem. Short interest reporting serves primarily as a technical indicator for quant funds and short-bias managers; routine monthly releases rarely catalyze broad-based repricing unless accompanied by systemic stress signals or extreme positioning.

Sector implication: This disclosure has negligible direct impact on equity sectors given its administrative nature. NDAQ, the exchange operator, may see minimal trading volatility from routine data releases. The consistent short interest metrics suggest market structure remains balanced without extreme leverage concerns.
