| A well known sentiment indicator is the NVI or Negative Volume Index for Comcast Corporation. The modern version of the indicator has received several enhancements added by Norman Fosback. The indicator is the proportion of the daily NVI as compared to the average daily NVI over the past year. The plot is orange below the unity line (neutral implication) and green above (bullish). |

Interpreting the Calibrated NVI for Comcast Corporation: The NVI is an elegant indicator based on sound principles but it should not be interpreted in a simplistic manner. The orange plot (NVI less than unity) is not considered bearish because a lowering of the NVI is a natural tendancy under many market conditions. When the plot is in the green area, it indicates that prices are rising on low volume sessions, which is contrary to the normal condition. This can be a tip off to "accumulation behaviour" on the part of someone or some group in the market. The indicator seems most significant when prices are falling and the NVI is rising, which indicates a market that is "buying on the dips". |

| For the trading week ending 1/21/2011, the weekly average closing altitude was 52.04 percent. The historical Closing Altitude is traced by the blue line in the chart above. 50 percent closing altitude is marked as the midline. If the closing prices happened to be exactly halfway between the high and low, they would be plotted on this midline. Values above the midline indicate that day traders have positive feelings toward CMCSA while traces below the midline are a sign that speculators are afraid to hold on to the issue overnight. The short-term trend is positive, with a slope of 16.55. Comcast Corporation stock prices are shown in red. |
