During the last week, the price has risen above the Parabolic SAR (stop and reversal). A Parabolic SAR below the price is a bullish signal, and it indicates that momentum is likely to remain in the upward direction. A Parabolic SAR is used as a trailing stop loss for long or short positions. It works best during strong trending periods. Use the following links to access Parabolic SAR Help, or use the Technical Stock Screener to see the list of stocks with the Parabolic SAR close to the price level.

During the last week, the price has moved above the moving average in the center of the Bollinger Bands. The distance between the Bollinger Bands is falling, and it was 4.83% on Friday. It is 58.25% lower than one year average. It indicates the period of low volatility of the stock price. 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.

Price is close to the 50 Day Moving Average. While daily technical indicators are overbought, the 50 Day Moving Average is considered a resistance 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.
