Actionable Intelligence: crossing the middle plane can be a signal to buy with the reverse direction being a signal to sell. In this particular selection from the DOW 30 three stocks are highlighted: INTEL is Orange, GE is Purple and IBM is Blue. Builder versions can control this themselves. This lens can be applied with one click on thousands of spaces with different stock groupings.
Description: Rate of change (ROC) is a technical analysis indicator showing the difference between today's closing price and the close N days ago (10 in this example). The ROC indicator shows trend by remaining above 100 while an uptrend is sustained, or below while a downtrend is sustained. A crossing up through 100 may be used as a signal to buy, or a crossing down through 100 as a signal to sell. How high (or how low when negative) the indicators get shows how strong the trend is. An example of a strong positive trend is CSCO which has an ROC spike in mid-August or AA breaking away at the end of the chart. This lens is a good place to start separating assets with an extreme high or low ROC for further investigation.
