Have Riverbed left the building with MAC?

|Includes: Riverbed Technology, Inc. (RVBD)

MACD (Moving Average Convergence/Divergence) is a good indicator of momentum. Is is not an indicator of overbought/oversold conditions. Standard MACD is the difference between the 12 day and 26 day exponential moving averages (NYSEMKT:EMA). The MACD signal line (MACD-S) is the 9 day EMA.

MACD signals are often used to determine when to buy or sell a stock. One such signal is a signal line crossover. A signal line crossover occurs when the MACD crosses the MACD-S.  Crossovers at positive or negative extremes can be deceptive. Like Elvis, Riverbed is looking like it may have left the building, with a near signal point crossover at a positive extreme.

Another MACD signal is the centerline crossover (MACD-C). When MACD moves above zero, it means the 12 day EMA has crossed the 26 day EMA. Some prefer to have both the MACD-S and MACD-C be positive.

A MACD divergence (MACD-D) occurs when the when a stock records a lower low and MACD records a higher low.

So where is Riverbed? Both Elvis and MAC says "hold on to her".
