The S&P 500 settled above the 1,200-mark on Wednesday's trading session, setting another key milestone for the market, and trading at its highest level since September 2008. In the past two months alone, the index posted a gain of nearly 13 percent, closing in the green 30 of the past 42 trading sessions. While the bullish momentum may be well received by some, the rate of acceleration might be making others nervous.
One tool widely used by technical traders to determine the momentum of a security is moving averages, which serve to smooth out price fluctuations, highlight trends, and define support and resistance levels. Indeed, since the March low last year, the S&P's 50-day moving average has been one of the benchmarks broadly used to spot any unusual patterns or extreme price movements.
In particular, investors pay attention to large movements away from moving averages, with the assumption that the index could be entering overbought levels. In the past six months and on average, for example, the S&P traded within 2 percent of its 50-day MA. As of Wednesday's close, the index is 6.5 percent over this mark.
So far in 2010, the S&P advanced nearly 9 percent. Keep in mind that the average yearly return for the index in the past 15 years, stands at 8 percent, with a median value of 14 percent.
Although a bullish trend may not necessarily mean that the market is overvalued, it could
certainly serve as point of reference as per when investors may start taking profits off the table.
Other technical indicators including the Relative Strength Index, which is at its highest level since October 2006, Moving Average Convergence / Divergence (MACD) and Bollinger Bands, are also pointing to an overbought market.
