U.S. equities gained in Wednesday’s midday trade after opening in the red due to the United States government entering its first shutdown in nearly seven years.

Weak jobs data raised the hopes of an interest rate cut later this month, after a report by ADP showed that private payrolls declined 32,000 in September, while Wall Street expected an addition of 45,000 jobs during the month. According to the CME FedWatch tool, the probability of a 25-basis-point rate cut in October has increased to 99%, up from 94.6% on Wednesday.

The SPDR S&P 500 ETF (SPY), which mirrors the S&P 500 index, was up 0.09% at the time of writing, while the Invesco QQQ Trust (QQQ), which mirrors the Nasdaq, rose 0.18%. The SPDR Dow Jones Industrial Average ETF Trust (DIA), which tracks the Dow Jones Industrial Average, edged up by 0.05%.
