Also shown is the uptrend that connects the low of 666.79 set in March 2009 goes through the low of 1074.77 set in October 2011. At the end of 2014 this trend is at 1584.26.
Note that the high in October 2007 was 1576.09. The all-time intraday high at 2005.04 set on Tuesday is 27% above the 2007 cycle high. The S&P 500 is up 200% from its March 2009 low. These statistics are another reason to book profits.

The monthly chart for the S&P 500 is positive but overbought with its five-month modified moving average at 1891.70 and its 120-month simple moving average at 1327.18, last tested 1165.17 in October 2011.
An important observation from this graph is to compare the strength since October 2011 to the Crash of 1987. That painful volatility can barely be seen at the lower left corner of the graph.
The S&P 500 has not had a 10% correction for a long time. This is another reason for caution. In my opinion a correction of 10% will not happen as my annual value level is 1539.1 which is downside of 23%.

If you are a buyer on weakness consider doing so on weakness to semiannual and annual value levels at $178.73 and $153.89, respectively.
