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.
