FYI: Below is a good look at where the S&P 500 and its ten sectors stand heading into the new year. These trading range charts help to identify both short and long-term trends, and they also give you an idea of how extended (to the upside or downside) a stock or index is at any given time. The light blue interior band represents each sector's "normal" trading range, which we calculate as between one standard deviation above and below the 50-day moving average (white line). The red zone represents between one and two standard deviations above the 50-day, and it is generally thought of as "overbought" territory. The green zone represents between one and two standard deviations below the 50-day, and it is generally thought of as "oversold" territory.
