SPX R-Squared Triggers an Intermediate-term Signal

By on Wednesday, April 14th, 2010 at 9:56 am

Tuesday’s recovery from the morning selloff favors lower prices today, but there were positive developments from an intermediate-term perspective. Note that the BKX and SOX diverged for the ninth time in the last fourteen sessions, a sign of a bullish rotational environment. Also note that the S&P’s gain pushed the 14-day R-Squared up to 90%, a sign of an unusually strong uptrend. R-squared values show the percentage of movement that can be explained by linear regression. When it reaches 90% or higher along with a positive slope, it’s a good indication that the rally has further to run over the intermediate-term. The last thirty occurrences are noted in the table below, along with the S&P’s performance over the next 1-3 weeks…
