The S&P 600 Small Cap Index gapped higher Thursday and may be ready to test the April highs at 397 because the S&P 400 Mid-Cap Index has already moved above its April highs. The RS analysis, which measures the performance of one index or group to another, turned positive in late September, indicating that small caps were starting to outperform the S&P 500. The RS has again turned up. The RS analysis looks stronger on the S&P 400 and it has moved above the April highs and is well above its rising WMA. Since the August lows, the S&P 400 is up 19.4% versus the S&P 500, which is up 15%.
