A bad earnings surprise is an event pattern in which a company issues an earnings announcement and the market interprets it as worse than expected. Nevertheless, in a bear market 61% have upward breakouts! In a bull market, 43% breakout upward. For those with downward breakouts, almost half (47%) bottom in one week, and 60% bottom in less than two weeks. Most of the time, a bad earnings surprise is nothing to be worried about providing the stock doesn't make a large intraday move (a wide price swing). Discovered by Thomas Bulkowski in the fall of 2003. For more information see pages 855 to 867 of the book Encyclopedia of Chart Patterns, Second Edition and read the following...

Identification Guidelines

Characteristic

Discussion

Price trend Downward leading to the announcement for the best performance.
Market This event pattern works best in a bear market.
Announcement The company announces earnings and the stock makes a large downward move that day or the next if the market was closed.
Wide swing Look for announcements in which price makes a large intraday swing, 2 or 3 times the average daily intraday price swing over the last month.
Yearly low For best performance, select announcements that occur within a third of the yearly low.
Downward breakout Since the price trend is downward leading to the pattern, trade only those announcements making a downward breakout. A breakout occurs when price closes below the lowest low posted on the announcement day.

Trading Tips

Trading Tactic

Explanation
Measure rule See the figure to the right. On the announcement day, subtract the intraday low (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 (point B) in the figure to the right).
Longer term For investors or traders with a longer-term investment horizon, do nothing as the decline is likely to be small. However, one bad surprise is likely followed by another next quarter.
Swingers For swing traders, consider selling a holding to minimize the loss. If price gaps downward and the gap is small, price may cover the gap in a few days.
Short For aggressive traders: In a bear market, wait for the breakout and then short the stock. It may bottom in less than a week.
Quick decline Expect a quick but shallow decline. Almost half the time price bottoms in less than a week and then rebounds.
More surprises A bad earnings surprise follows a bad earnings surprise 74% of the time.

The Measure Rule

Example

 pattern example

The above figure shows an earnings announcement which the market took as bad news. Price began a strong move up at point A. When the bad earnings announcement came at B, the stock was overbought and ripe to fall. Price traded in a large price range on the announcement day and then tumbled thereafter. Price pulled back, allowing nimble traders to either exit a long position or add to a short position before the decline resumed. Price dropped from over 70 to 55 and change.
