Makes a great gift

Periodically, retailers announce same-store sales numbers (sometimes called ’comparable store sales’). Usually, these are sales results for stores open at least a year. Bad same-store sales make an event pattern on which you can trade. Discovered by Thomas Bulkowski in the fall of 2003. For more information see pages 908 to 920 of the book Encyclopedia of Chart Patterns, Second Edition and read the following...

Identification Guidelines

Characteristic Discussion
Price trend Usually found in a price downtrend.
Announcement The company announces monthly or quarterly same-store sales numbers.
Wide swing Look for announcements in which price makes a large intraday swing, 2 or 3 times the average daily price swing over the last month.
Downward breakout A breakout occurs when price closes below the lowest low posted on the announcement day.
Volume Above the 30-day average, usually
Market Works best in a bear market.

Trading Tips

Trading Tactic Explanation
Measure rule Reference The Measure Rule figure to the right. On the announcement day, subtract the intraday low (point B) from the high (A) and multiply it by the above “percentage meeting price target.” Subtract the result from the intraday low (B) to get a price target (C).
Confirmation Wait for price to confirm the pattern because traders may push price up instead. A downward breakout (confirmation) happens when price closes below the low posted on the announcement day.
Sell Sell a long holding or short the stock after confirmation.
Repetition Another bad same-store sales announcement often follows the first one.
Yearly middle Patterns in the middle third of the yearly price range show the best performance.
Bottom Price may bottom quickly. Over 60% bottom in less than 2 weeks in a bull market, 57% in a bear market.

Example

Same-store sales event pattern example

The above figure shows an example of a same-store sales event pattern. Price leaves a consolidation region at A and shoots up to B. Then the stock begins a long slide downward. Along the way, the same-store sales number becomes public and the results send the stock down. Price attempts a pullback in February, but then price resumes the downward move.
