During the last week, daily MACD line has moved below its signal line. Such crossover is considered a bearish signal.

During the last week, the price has fallen below the Parabolic SAR (stop and reversal). A Parabolic SAR above the price is a bearish signal, and it indicates that momentum is likely to remain in the downward direction. A Parabolic SAR is used as a trailing stop loss for long or short positions. It works best during strong trending periods.

During the last week, the price has declined below the moving average in the center of the Bollinger Bands. The Bollinger Bands are often used with a non-oscillator indicator like chart patterns or a trendline. The signals are considered more reliable if these indicators confirm the recommendation of the Bollinger Bands. Use the following links to access the Bollinger Bands Help, or use the Technical Stock Screener to see the list of stocks with the price above the Upper Bollinger Band or below the Lower Bollinger Band.

During the last week, the price has crossed below the 50 Day Moving Average. While the medium-term trend is up and daily technical indicators are oversold, the 50 Day Moving Average is considered a support level. The moving average crossover signals work better when the stock develops a strong trend, but they are ineffective when the stock is in a trading range. Moving average crossover systems can be effective, but should be used in conjunction with trend patterns, momentum indicators, candlesticks and other aspects of technical analysis. Use the following links to access Moving Average Crossover trading technique, or use the Technical Stock Screener to see the list of stocks with the Moving Average close to the price level.
