On Symmetrical Triangles


by Thomas Bulkowski

You might have seen triangle formations and wondered what they were all about. You might have been caught on the losing side of a descending triangle and wondered what happened. For those of you who've wondered what was going on, here's the first part of a two-part refresher course on the three basic types of triangle formations and how to use them in your investment decisions.

"Before I buy a stock, I search the price chart for familiar patterns. The last thing I want to do is to purchase a stock, only to see it drop down beyond my stop, resulting in a loss. Checking for technical patterns allows me to look for some indication that I should not buy a stock. Over time, I find that my memory for various chart patterns gets somewhat fuzzy and I need to refresh my memory for what to look for. Here, then, is a description of symmetrical triangle formations and their significance in my battle plan in the market."

FIGURE 1: A TYPICAL SYMMETRICAL TRIANGLE. Note the narrowing stock price, as the minor highs are lower and the minor lows are higher. Volume generally diminishes as time progresses, especially before the breakout.
"Figure 1 shows a typical symmetrical triangle in ice cream manufacturer Ben & Jerry's, Inc. [BJICA]. The triangle was formed in May 1995 with a rising stock price and diminishing volume. The stock hit a high of 15-1/2 for several days, then retreated to 13-1/2. It rose to 14-3/4 and again retreated to 13-1/2. Over the following days, the daily highs and lows narrowed until the spread was just a quarter of a point; the high was 14 and the low was 13-3/4 on July 31. Volume on that day had diminished to 10,500 shares. The next day volume exploded to 300,000 shares and the price took off to 17-1/4. Welcome to the world of symmetrical triangles!"
