The S&P 500 flies high supported by better-than-expected third-quarter earnings. The index has reached the previous all-time high at 4550.
A breakout may trigger a runaway rally. Nonetheless, a repeatedly overbought RSI may cause a limited pullback as buyers take profit.
A drop below the immediate support at 4515 would pull the trigger. 4445 would be next as it coincides with the 38.2% Fibonacci retracement level of the October rally. The bulls are likely to buy the dips though after sentiment turns optimistic.
