US stocks soar over 2% after September's higher than expected inflation report sparks wild turnaround

• US stocks surged more than 2% in a wild trading session after September's CPI report doubled expectations at 0.4% month-over-month.
• The September inflation report poured cold water on hopes that the Fed will pivot away from its interest rate hikes anytime soon.
• Fed Fund Futures are now pricing in a 75 basis point rate hike in both November and December.

US stocks soared more than 2% on Thursday, recovering from an initial decline of more than 2% after September's CPI report showed inflation continues to hit levels not seen in four decades.

The S&P 500 was down 2.4% at its low for the day, before it recovered all of those losses and surged as much as 3%. The Dow Jones Industrial Average saw a 1,500 point intraday swing.

The reversal came after the S&P 500 tested 3,500, briefly hitting a low of 3,491. The 3,500 level represents a 50% retracement of the March 2020 low at about 2,200 and the January high of about 4,800.

Month-over-month inflation hit 0.4%, double the expectation for a rise of just 0.2%. CPI rose 8.2% year-over-year, which was above estimates for a rise of 8.1%. Even when excluding food and energy prices, CPI rose 0.6% month-over-month, which was ahead of estimates for a rise of 0.4%.

The hot CPI report erased all hopes that the Fed will soon pivot away from its aggressive rate hikes anytime soon. The Fed is now expected to hike interest rates 75 basis points in both November and December, according to the CME FedWatch Tool.

The shock CPI report erased early morning gains in the market, as the S&P 500 was briefly up about 1% after the UK government signaled a policy reversal of its proposed tax cut plans. However, the massive rally kicked off not long after the open, with the Dow up by more than 600 points by 11:30 a.m.

• S&P 500: 3,669.86, up 2.6%
• Dow Jones Industrial Average: 30,038.06, up 2.83% (827.21 points)
• Nasdaq Composite: 10,649.15, up 2.23%
