Several signals have flipped to "Sell" over the past week thanks to weaker than expected ISM data in both manufacturing and services. Large-caps ended the week modestly down but small-caps are showing much more technical weakness here.Treasuries remain well above their 200-day moving averages but many markers have turned negative as volatility rises. The rapid rebound in Treasuries following September's mini-correction has pushed the group (and even corporates) into overbought territory suggesting that traders should be cautious in fixed income investments.Strength in gold also suggests caution as investors turn defensive following last week's events. It's still all about the dollar as well. I suspect the dollar isn't necessarily strong but it's in better shape relative to other global currencies. A run to 100 in the dollar index seems more likely than not at this point.Here is the full scorecard for the week ahead.
