the formation sloped upward and gave character to the broadening formation.

Graph depicts the Price pulls back to the base of the formation. Pullbacks occur often in ascending broadening formations.

      The next day volume dried up, but there was enough momentum remaining for another try at the summit. When the attempt failed, the smart money headed back to base camp and volume receded further. As price collapsed, other investors joined in the retreat and volume moved up. In less than 2 weeks, price was back at the lower trendline.

      Another feeble attempt at a new high floundered on unremarkable volume. The stock moved horizontally and stalled out—a partial rise that often spells trouble for bulls. On 4 June, price dropped on high volume and returned to the horizontal trendline. The stock paused there for just over a week before moving down and punching through the support level at 12.25.

      A pullback in bull markets is quite common for ascending broadening formations, so it is no surprise that after a rapid 13% retreat, the stock turned around and pulled back to the base of the pattern. Although not shown in the figure, the stock continued moving upward until it began forming another ascending broadening pattern in late October with a base at 16.50.

      The ascending broadening formation represents the desire of investors and traders to own the stock at a fixed price, in this case about 12.25. Their buying enthusiasm pushes price higher until mounting selling pressure causes a halt to the rise and sends the stock tumbling. With each attempt, fewer people are left willing to sell their shares until they receive an even higher price, so a broadening range of prices appears at the top.

      Eventually, the buying enthusiasm at the base of the pattern collapses and removes the support for the stock. A downward breakout occurs when the stock punches through the support level and declines. It continues moving down until reaching a point where other investors perceive significant value and buy the stock.

      Upward breakouts see price continue the fight with the bulls overwhelming the bears. Sometimes, the stock will bump up against overhead resistance set up by extending the top trendline from the broadening pattern. It's as if the bulls know there's a turn coming (at the extended trendline), so they back off and let selling pressure take the stock down again.

      How do you find an ascending broadening formation? To answer the question, read the selection guidelines outlined in Table 9.1. Microscopes or telescopes are optional. While chewing on the table, look at Figure 9.3, an ascending broadening formation on the weekly scale.

Characteristic Discussion
Appearance Looks like a megaphone with the base of the formation horizontal and bounded on the top by an up‐sloping trendline.
Horizontal bottom support line A horizontal, or nearly so, trendline that connects the minor lows.
Up‐sloping top trendline An up‐sloping trendline bounds the expanding price series on top.
Touches Look for at least five trendline touches, three on one trendline and two on the other.
Whitespace Price should bounce from trendline to trendline, overwriting whitespace from the pattern.
Price action before breakout Price sometimes moves horizontally for many months before moving outside the formation high or low.
Breakout direction Price can break out of the pattern in either direction, but favors an upward breakout.
Volume Trends upward most often.
Support and resistance Follows the two trendlines into the future.
Graph depicts the Support and resistance areas on a weekly time scale. They appear along the trendline axis and can extend far into the future, as in this case.

      Up‐sloping top trendline. Price should touch the top trendline at least twice, in two minor highs.

      Touches. Price should come near to or touch each trendline in minor highs or minor lows. At least five touches are needed to qualify the pattern, but be flexible. Don't count it as a touch when price slices through a trendline. That often occurs at the start and breakout from the pattern. If price doesn't touch a trendline at a minor high or minor low, then it doesn't count as a touch.

      Whitespace. Price should bounce across the pattern from top to bottom frequently, filling the whitespace with price movement.

      Price action before breakout. In some ascending broadening formations, price moves sideways for many months while trying to decide on a breakout direction. Eventually, price rises above the formation top or slides through the bottom trendline and stages a breakout.

      Breakout direction. The breakout favors an upward direction, but it's almost random. A breakout occurs when price closes outside the trendline boundary.

      Volume. The volume trend is usually upward. Don't discard a chart pattern because volume trends in a direction different from what you expect.

      Support and resistance. I chose Figure 9.3 because it shows the two common areas of support and resistance. These areas follow the trendlines. Along the base of the formation projected into the future, the support area repels the decline over 2 years after the formation ends. The rising trendline tells a similar tale; it repels price three times nearly a year later.

      The implications of this observation are profound. If you own a stock and it is breaking out to new highs, it would be nice to predict how high price may rise. One way to do that is to search for formations such as this one. Many times, extending the trendlines into the future will predict areas of support and resistance.

      Although the trendline did not predict the absolute high, it did suggest when price would stall. The resistance area turned out to be a good opportunity to sell the stock.
