Market-on-open order imbalances released Tuesday show a $141 million net sell imbalance for the S&P 500 index. The same data set recorded a $16 million net buy imbalance for the Nasdaq 100, an $8 million net buy imbalance for the Dow 30, and a $5 million net buy imbalance for the Magnificent 7 stocks.

The figures reflect the difference between buy and sell orders submitted before the regular trading session begins.
