NEW YORK (TheStreet) -- Shares of Comcast (CMCSA) traded to an all-time intraday high of $60.85 on April 23 just before the company withdrew its offer to buy Time Warner Cable (TWC). Comcast will report its quarterly results before the opening bell on Monday and analysts expect the company to earn 74 cents a share for its quarter ended in March.
Let's look at the daily and weekly charts for Comcast and provide the key technical levels at which to buy on weakness and the key technical levels at which to sell on strength.
Investors not familiar with technical analysis should begin with the notion that a price chart for a stock shows a road map of past price performance, which provides guidance for predicting future share price direction.
Here's how to read a daily chart. There are two moving averages to follow -- the 50-day simple moving average is in blue while the 200-day simple moving average is in green.
Here's how to read a weekly chart. This chart shows weekly price bars going back to the beginning of 2007 and thus includes the Crash of 2008, then the current bull market for stocks that began in March 2009. The red line tracks the ups and downs of the key weekly moving average. The green line is the 200-week simple moving average. The red line that oscillates along the bottom of the chart is the momentum reading on a scale of 00.00 to 100.00. A reading below 20.00 is oversold and a reading above 80.00 is overbought.
