zt BEAR FLAG

Bear Flag

Bear Flag is a sharp, strong volume decline, several days of sideways to higher price action on much weaker volume followed by a second, sharp decline to new lows on strong volume.

The technical target for a bear flag pattern is derived by subtracting the height of the flag pole from the eventual breakout level at point (e).

Even though flags and pennants are common formations, identification guidelines should not be taken lightly. It is important that flags and pennants are preceded by a sharp advance or decline. Without a sharp move, the reliability of the formation becomes questionable and trading could carry added risk. Look for volume confirmation on the initial move, consolidation and resumption to augment the robustness of pattern identification.

 

 

 

Flags and Pennants can be categorized as continuation patterns. They usually represent only brief pauses in a dynamic stock. They are typically seen right after a big, quick move. The stock then usually takes off again in the same direction. Research has shown that these patterns are some of the most reliable continuation patterns

Bearish flags are comprised of higher tops and higher bottoms. "Bear" flags also have a tendency to slope against the trend. Their trendlines run parallel as well.

• Sharp Move: To be considered a continuation pattern, there should be evidence of a prior trend. Flags and pennants require evidence of a sharp advance or decline on heavy volume. These moves usually occur on heavy volume and can contain gaps. This move usually represents the first leg of a significant advance or decline and the flag/pennant is merely a pause.
• Flagpole: The flagpole is the distance from the first resistance or support break to the high or low of the flag/pennant. The sharp advance (or decline) that forms the flagpole should break a trend line or resistance/support level. A line extending up from this break to the high of the flag/pennant forms the flagpole.
• Flag: A flag is a small rectangle pattern that slopes against the previous trend. If the previous move was up, then the flag would slope down. If the move was down, then the flag would slope up. Because flags are usually too short in duration to actually have reaction highs and lows, the price action just needs to be contained within two parallel trend lines.
• Pennant: A pennant is a small symmetrical triangle that begins wide and converges as the pattern matures (like a cone). The slope is usually neutral. Sometimes there will not be specific reaction highs and lows from which to draw the trend lines and the price action should just be contained within the converging trend lines.
• Duration: Flags and pennants are short-term patterns that can last from 1 to 12 weeks. Ideally, these patterns will form between 1 and 4 weeks. Once a flag becomes more than 12 weeks old, it would be classified as a rectangle. A pennant more than 12 weeks old would turn into a symmetrical triangle. The reliability of patterns that fall between 8 and 12 weeks is debatable.
• Break: For a bullish flag or pennant, a break above resistance signals that the previous advance has resumed. For a bearish flag or pennant, a break below support signals that the previous decline has resumed.
• Volume: Volume should be heavy during the advance or decline that forms the flagpole. Heavy volume provides legitimacy for the sudden and sharp move that creates the flagpole. An expansion of volume on the resistance (support) break lends credence to the validity of the formation and the likelihood of continuation.
• Targets: The length of the flagpole can be applied to the resistance break or support break of the flag/pennant to estimate the advance or decline.
