The S&P 500 and the Nasdaq have been setting records as the market recovers from the correction of September and October, but the IBD 50 has lagged, still trading slightly below an intraday high set Sept. 3. That’s been a hallmark of the usually market-leading index this year. The Relative Strength line has failed to recover to the high set in February. But the IBD 50 index had a good week, rising 1.7% vs. 0.2% for the S&P 500.
