"Inflation Threatens Stock Market Bulls' Regained Control"

The stock market bulls are regaining control after two months of losses, with the Dow, Nasdaq, and S&P 500 extending their winning streaks. However, the September Consumer Price Index (CPI) report could challenge the rally if it suggests that the Fed has not been able to contain inflation. JPMorgan expects a bullish CPI number, but warns that a super-hot CPI print could lead to a market tumble as investors anticipate more forceful action from the Fed. Despite this, seasonal trends are shifting from bearish to bullish, providing a tailwind for stocks, and historical data suggests that October's trading action might favor the bulls.
