Jim Cramer says that there is always a bull market somewhere and he will find it for you. Well you don't need Jim Cramer. Just go to stockcharts.com and set up a page called SPYDRs. On that page put the 9 ETFs known as SPYDRs. These are XLF - finance, XLK - tech, XLI - industrial, XLB - materials, XLE - energy, XLU - utilities, XLV - medical care, XLP - consumer staples, and, XLY - consumer discretionary. With those charts put some measure of overbought/oversold such as Slow Stochastics and watch the indicator. When everything but one or two are overbought attack those sectors that are oversold. This was XLE and XLU on a recent occassion (like for the past 4 weeks or so). You wait until one of the major indices such as OIH shows a turnaround and then move your assets to that sector.
If you do something like this you will always know where the bull market is coming next.
