S&P 500 – Daily Chart through 5/12/09



As seen above, the S&P 500 is still in an up sloping price channel (red lines) and also above near term price support (green line) at 875 level. As long as price stay above this level any sell-off should be contained and shallow. Additionally this area is also significant because it is the convergence of a secondary up trend line (purple dotted line) and price support. If we violate this level a deeper retesting sequence would take place.

The indicator slice below the above chart is a 21-day Rate of Change (ROC). This ROC indicator looks at the rate at which prices are rising or falling or stated another way whether price momentum is accelerating or decelerating. As observed in the chart above even though prices have risen they have not risen at the same rate as which they did to start the rally. This divergence between price and momentum can typically be a warning sign that a near-term trend change may be taking place.

While these and other momentum indicators can be leading indicators at times they can also be coincident in many cases as well so we would need to see more evidence that not only upward price acceleration deteriorated but also that it was shift and re-accelerating downward. Confirmation of this would only happen if we broke the aforementioned support level.
