Equity markets tried to advance on Wednesday but could not hold the gain. The result is another day of sideways trading near recent highs in a string of sideways moves that are beginning to look like a frothy market top. Wednesday's action was driven by a hotter-than-expected revision to Q3 GDP and reinvigorated fear of higher interest rates for longer.

Without a catalyst to drive it higher, the odds are high that the S&P 500 will begin to correct soon. The indicators point to an overbought market and waning momentum about to swing into negative territory. Such a move would confirm a bearish sentiment with the index trading at critical resistance and could lead sellers into the market. One potential catalyst will be released today, the PCE price index, and the next FOMC meeting is only 2 weeks away.
