Inflation worries, higher yields, and the dollar rising typically spells trouble for equities.
I mentioned in the Live Trading Room yesterday that if the S&P 500 breaks 4,400 we can see 4,370. An overbought market can stay overbought, and an oversold market can stay oversold.
This has been a slow bleed lower. It's not an easy market to trade, so I tell people to back away or trade very small.
