NEW YORK (TheStreet) -- The Dow utility average gained momentum in mid-March as transports and small caps set tradable highs. Utility strength continued into April as Dow industrials and S&P 500 set interim highs on April 11. While the major equity averages hesitated, utilities continued to a high at 537.86 into April 30, up 18.7% year to date at that time versus a 12.0% gain for the S&P 500. Today the utility average is up 12.7% year to date with the S&P 500 up 14.6%.

The main reason for this rotation was that the Dow utility average became extremely overbought on its weekly chart. At the high the 12x3x3 weekly slow stochastic reading was 97.23 on a scale of zero to 100, where readings above 80.00 are overbought.

The Dow utility average peaked between its quarterly pivot at 524.17 and its annual risky level at 540.37 then tested its monthly pivot at $509.53 on Friday and Monday. You can trade the utilities sector using the

($39.62). Note that XLU has held its 50-day simple moving average at $39.46 with my monthly value level just below at $39.09. After testing $41.44 on April 30, XLU was pulled back down due to the power of the annual and quarterly pivots at $40.52 and $40.27. My semiannual value level is $36.48 with an annual risky level at $43.47.
