The chart below is the spread between the relative strength leaders and relative strength laggards (universe of mid and large cap stocks). When the chart is rising, relative strength leaders are performing better than relative strength laggards. As of 8/2/2010:
RS leaders and laggards continue to mark time without either one substantially distinguishing itself from the other in terms of performance. This transition from a declining spread to what may well be a period of a rising spread has now lasted for over a year.
