S&P 500: be cautious for a top

As predicted in my last blog, S&P 500 had a nice bullish run last week. Let's re-examine the current market in the following figure:
After the bullish run, the market became over-bought. Three short term bearish signs are emerging: 1. RSI is approaching a short term max. 2. The price is almost over it's 2 SD range. 3. The price is very close to the reversed head-shoulder rebound level: 115. This does not mean an immediate trend reversal and short, but this does mean to be cautious and if necessary take profit. What I can say at this point is: SET STOP now! The chance of a pullback next week is increasing. The level of pullback should be closely watched. If it's too big, a possible double head pattern can form. In case this pattern forms, it will be a very bearish sign in combination of the divergent MACD I mentioned in the last blog.
