Broadening Tops - Failed and Successful

"Broadening Top Pattern



WHEN YOU SEE A BROADENING TOP, THE MARKET WILL EVENTUALLY DROP

Major reversals in trend--those that mark the turn from a bull to a bear market--can take the shape of many price patterns.
Stocks or markets can top by creating, for example, head and shoulders or descending triangles. One of the most difficult
patterns to predict, however, is the broadening top.

A broadening top is hard for the swing trader to spot because it is seen far less frequently than other important price
patterns. It can be visualized, however, as opposite to a symmetrical triangle. Whereas the symmetrical triangle consists
of two lines that converge, the trendlines of the broadening top instead diverge. The shape that best captures this pattern is
that of a megaphone.

The classic technical analysis text by Edwards and Magee characterizes a broadening top as a market that lacks
intelligent sponsorship. It is one in which the public is being whipped around and driven this way and that by rumors. As such,
volume during the broadening top pattern tends to be irregular. During some rallies volume may expand, but during others it
tends to be tepid. The same pattern applies on pullbacks. Because it is so unpredictable, the broadening top pattern is
extremely difficult to trade. There is no clear breakout to either the upside or downside edge of the pattern.

Below is an example of a stock that is in a broadening top pattern, Boise Cascade (BCC). I started the chart in December
2003, just before the formation began in January 2004. Note the lower lows in February and March, which mark the beginning of
the formation. However, also note the ability of BCC to continue to make marginal new highs. In fact, toward the end of this
chart it reached a new high peak of $37.80 (although as the star candle shows, it quickly retreated from this level). Note the
erratic volume pattern, as the stock saw a pickup in volume on both rallies and declines.


Below you will find a chart of the S&P 500.]/b] I have included the 150-day moving average to show that prices have
gone below this key measure but have now popped back above it. Within the context of a broadening top, the S&P could reach a
marginal new high of say 1170 without changing this pattern's interpretation.

What would cause me to reject the broadening top interpretation?

First, the S&P would have to break out above 1163.
Second, it would have to hold the breakout level on a pullback.
And third, it would need to re-establish an uptrend by making a series of higher lows and higher highs.

Such behavior would keep the index above a rising 150-day moving average and would turn the March-May pattern of lower lows into
an aberration. Time will tell if the buying power remains to
re-ignite this kind of bull market. Until proven otherwise, however, the broadening top explains the market's current choppy
action." End Article Quote
