A Wall Street firm lowered its S&P 500 price target for the year, marking what analysts described as a rare reversal after a period in which most firms had been raising their forecasts. The cut comes amid rising Treasury yields, elevated oil prices, and uncertainty over the Federal Reserve's policy path. Adding to the cautious tone, the Dow Jones Industrial Average posted its worst performance during the first 10 days of September since 2008, with commentators noting the historical tendency for weak September starts to presage further volatility. The combination of the lowered target and the Dow's poor start reinforced concerns that markets face a difficult stretch heading into the Fed's meeting.
