TASC 2012-08 | Sector Rotation Model (Siligardos)


Traders' Tip text

The WealthScript code to produce the SRMind oscillator is given below. Wealth-Lab customers should create and update a DataSet with the Sector ETF symbols and then click any symbol in any DataSet to run the script. Solidly positive for virtually every day 2012, the SRMind oscillator appears to suggest that the S&P 500’s recent setback to the 200-day moving average (Figuire 1) will be just that – a setback, despite the fundamental backdrop of Europe’s expanding crisis.
