If China's on your info radar then you might want to check Mauldin's recent post. The before and after photos of Shanghai are an eye-opener and his Chinese economy forensics are factors to consider if you have an exposure in that area.
Here's an update to the Schwab no-fee ETF model since several readers have asked about it. You obviously have to have a Schwab account to trade these for free and you can now trade them intraday for no fee although the model reflects our usual strategy of buying on the close as selling or holding according to the next's day ranking. SCHB is the proxy for SPY, SCHA is the IWM proxy, SCHD is the SPY dividend proxy, SCHX is the NYSE large cap proxy, SPLV is a low volatility version of SPY. All have decent daily volume (>250K shares) and 1-2 penny spreads. We use an across the boards .6% limit stop per our other M3 models. Just something to consider, not an advertisement for Schwab.
Here's a version that includes XLU (SPDR sector Utilities ETF) (NOT no-fee)
And here's and update to the SPY VDX and teh XLU VDX. I show the XLU version in response to readers questions as to my comments that XLU is overbought.
Note that the VDI+ and the VDI- on the SPY chart are both downslope. THIS IS VERY RARE, reflecting technical instability and likely warning of a big move ahead.
