Gaurav, thanks for the link. I will read it with interest. Causality is quite tricky to measure properly, especially between macro indicators and market, or between 2 macro indicators as it could be stable during one regime but can reverse under certain conditions.

@Johan, completely agree, thats a good point. The reason for this reversal is most likely attributed to the fact that one factor depends on a variety of factors (instead of just one that I considered). In addition to that, the factor's weight in causing these changes as well.

Another point, I'd like to mention is that one can never really eliminate spurious regressions entirely which can again affect the results !
