How to Detrend Volatility Index (VIX) with PPO


Generally, the Volatility Index (VIX) is in an uptrend or downtrend constantly, and this feature makes it challenging to pinpoint extremes or cycles.  Percent Price Oscillator (PPO) is applied to detrend the VIX. 

The Exponential Moving Average (EMA) is another type of moving average.  More weight on the latest data is adopted to compute its value.  Therefore, EMA is more sensitive to more recent price changes than the well-known simple moving average (SMA).  It is tapped to derive PPO and other indicators. 

PPO (10,50,1) is calculated by the difference between the 10-day EMA and the 50-day EMA, divided by the 50-day EMA.  Its value serves as the difference in percentage between the 10-day EMA and the 50-day EMA. 

PPO (10,50,1) has a positive value when the VIX 10-day EMA exceeds the VIX 50-day EMA, likewise. Investors can customize the PPO by modifying the combination of exponential moving averages. Lets’ use example PPO (20,50,1). The parameter 1 is fixed, which is utilized to merge the signal line moving average with the index VIX.  

          It requires some technical tips to further demonstrate the VIX as a PPO (10,50,1) that can compare with the underlying stock index S&P 500.
