Why did the S&P 500 drop today?

S&P 500 today fell on a mix of war risk, $112 Brent crude, and rising Treasury yields. Higher oil stokes inflation fears and pushes rate cuts further out. That lifts discount rates and pressures growth valuations, which broadens selling across sectors and styles.

What levels should traders watch on the S&P 500?

Key support sits near 6,540–6,560, with resistance around the 200-day near 6,616 and today’s range top near 6,636. Above that, the 6,770–6,873 area is a bigger test. A strong close back over the 200-day would help stabilize the short-term picture.

How do oil prices and yields affect stocks?

When oil prices surge, input costs rise and margins can compress. If Treasury yields rise at the same time, the discount rate on future earnings goes up. Both forces tend to weigh on long-duration growth and cyclicals, while energy may see relative strength.

Is this a buy-the-dip setup?

It can be for nimble traders, since RSI is oversold. But the downtrend is strong and volume favors sellers. Consider partial entries, tight risk management, and focus on quality. A close back above the 200-day and improving breadth would make a stronger case.
