The Dow Jones Industrial Average and S&P 500 are within 51 and eight points, respectively, of key Fibonacci levels. Meanwhile, the market remains overbought. These data points do not signal a market that must decline, but does warrant caution. An overbought market approaching resistance is not the best entry point so we must question the source of incremental strength.
