S&P 500 at the worst levels of the day

The S&P 500 has alternated between gains and losses today but it's at a session low, down 15 points 2728.

Today is the final trading day of February and the monthly chart shows what a rock-and-roll month it was. It also highlights how the rebound from the lows might not be as solid as it looks.

That red candle is a warning sign and with the US dollar turning around and fresh lows in the euro, loonie and pound today, it's not a great sign.
