Courtesy of Sabrient Systems and Gradient Analytics Earnings season is in full swing, and on balance, investors are liking what they hear. Tech leaders Google (GOOG) and IBM (IBM) got bought in truckloads after their fine earnings reports, although Apple (AAPL) disappointed after the close on Wednesday. By and large, earnings reports have been positive, including diverse companies like duPont (DD), Johnson & Johnson (JNJ), Verizon (VZ), and Intuitive Surgical (ISRG).

However, oscillators RSI, MACD, and Slow Stochastic have become extremely overbought as bulls refuse to give up much ground. I have drawn a possible line of uptrend support starting from the intraday low that filled and tested the morning gap up on November 19 (Thanksgiving week). SPY was only temporarily violated in the final few days of 2012 when the fiscal cliff was still in doubt, but quickly recovered after the deal was done. Perhaps Apple’s disappointing quarterly report will give investors a reason to finally allow a pullback to retest support levels, starting with the convergence of the uptrend line and prior resistance-turned-support at 148, followed…
