On the technical side, yesterday the S&P 500 rose to $4,383, suggesting the index could perform well today. Bullish traders are expected to steer the S&P 500 towards testing $4,433.

If there's low demand for opening long positions near $4,383, the index could break through it downwards and plunge towards the lows at $4,319 and $4,265, nullifying the efforts of bulls.
