    SPY - VIX statistical relationship ( daily close ):


    zone : uptrend

    percentile : 41.5% [ normal ]


    Wavelet Discontinuity Watch (daily close ) :


    Risk of crash is low but starting to increase.


    Higher frequencies starting to increase. Trend change pattern emerging.



    Overall commentary for Jan/07:


    Neuralnet trend model still in high confidence uptrend zone.

    Main trend up, with increasing momentum.

    Overall volatility is historically low but rising. Relative volatility is rising, usually this signals short-term trend changes.

    MatLab´s Markov model updated the regime probabilities, downtrend regime went from 7.4% to 10.4%. If it keeps rising chances are good we are entering at least in a short term correction.

    Wavelet model probability of a discontinuity is still low but increasing.

    The wavelet pattern currently emerging leads to a correction or a crash, but still  no signal yet.

    Model suggested positioning is small short with stops on SPY highs around 127.8.

    Good trading.
