The S&P 500 has been in an uptrend for 8 weeks now but Vectorvest still has a C-DN. On June 4, 2012 the S&P 500 hit a low of 1266 and on July 27, 2012 it closed at 1385, a gain of 119 points. This does not make any sense. Price action trumps all and an 8 week rally with a gain of 119 points is nothing to sneeze at. A look at weekly and monthly price data would improve results. Also chart pattern recognition should be added to identify continuation patterns such as bull and bear flags and double tops and double bottoms.
