You generally can't go wrong following the trend in a clear bull market. For almost three months this has been the rule for corn. Trending markets generally cycle from undervalued, to valued, and then to overvalued. By the end of September, it appeared the trend was complete. New market information in October gave the dominant trend new life. Another factor to note about this breakout is a large 26.25 cents gap has been left. Instead of being defined as a "common gap," which has a good chance of being filled, this marks a breakaway gap. Technical analyst Ken Shaleen has always argued for the importance of monitoring volume. A high volume breakout lessens the chance the market will go down to fill the gap.
