The S&P 500 once again breaks records, and its no accident.

Days after President Trumpnnouced his new tax plan, which promises to cut taxes for the middle class as well as simplify the tax code, the S&P 500 is on pace to close at a record high for the second day in a row. The S&P 500 is a financial index that provides a glimpse of how the US stock market is performing.

Here are some more details about the Stock Market’s performance:

The S&P 500 and Nasdaq reached new records on Friday, Sept. 29, with the S&P 500 index on track to close at all-time highs for the second day in a row.

The benchmark S&P 500 increased 0.3%, hitting a record intraday high of 2,517.97. The Dow Jones Industrial Average was down 0.09%, and the Nasdaq rose 0.65% to a high of 6,495.

So far this month, the S&P 500 has risen 1.6%, the Dow 2%, and the Nasdaq 0.4%. Wall Street is on track to close out its least volatile month on record. The range between the S&P 500 Index’s day-to-day session highs and session lows has been just 0.39%, which is the smallest average range during September since at least 1970. Gains for the S&P 500 would mark its sixth straight month in the green.

For the quarter, the S&P 500 has climbed around 5%, the Dow 4.8%, and the Nasdaq 4.8%. Stock markets have managed to clock steady gains, and new records, even as tensions between the U.S. and North Korea threatened to spill over into warfare. The second-quarter earnings season, which occurred earlier in the third quarter, was generally positive.

Already, expectations for the third quarter have been tempered after hurricanes battered the southern U.S. and the U.S. territory of Puerto Rico. The effect of Hurricanes Harvey, Irma and Maria will likely put a dent in growth for the July-September quarter. Estimates have third-quarter GDP growth at 2.5%, according to FactSet. An initial estimate will be published on Oct. 27.

Consumer staples stocks took the lead on markets for a second day. Tyson Foods Inc. (TSN – Get Report) was among the best performers after increasing profit guidance thanks to strong performance in beef sales.

Other consumer stocks on the rise included Unilever PLC (UL) , McCormick & Co.  (MKC – Get Report) , Coty Inc. (COTY – Get Report)  and Hain Celestrial Group Inc. (HAIN – Get Report) .

The savings rate held at 3.6%, while consumer spending increased 0.1%. The personal consumption expenditure index rose by 0.2%. The core rate gained 0.1%, its weakest since November 2015.
