Below we present one of Birinyi's familiar indicators, an analysis of stocks that are either overbought, oversold or within their normal trading range. The blue range shown by the indicators below represents a stock's normal trading range, which is one standard deviation above and below its 50-day moving average. The extremes shown in the chart represent the maximum and minimum 50-day spread, or the greatest difference between the price and 50-day moving average over the last year.
Currently Wal-Mart is at its "theoretical high," meaning that the stock is the most overbought it has been in the last year. GE and BAC on the other hand are near their theoretical lows (or the most oversold they have been within the last year). CVX, DD, JNJ, PG, and XOM are overbought; DIS, GM, and PFE are oversold.
