Making money by trading stocks or other assets often depends on spotting and following trends. However, one of the biggest risks for traders is getting caught in a market reversal.
A reversal happens when the price trend of a stock or asset suddenly changes direction.
Recognizing the signs of a potential reversal can help traders decide when to exit their positions to avoid losses.
At the same time, these signals can also be used to spot new trading opportunities, as a reversal could lead to a fresh trend forming.
In his book The Logical Trader, Mark Fisher presents several methods to identify potential market tops and bottoms.
His techniques serve a similar purpose to classic chart patterns like the head and shoulders or double top/bottom formations, as detailed in Thomas Bulkowski’s Encyclopedia of Chart Patterns.
However, Fisher’s strategies provide earlier warning signals, allowing traders to act before a trend reversal fully takes shape.
The Sushi Roll Trading Pattern
One of the techniques Fisher introduces is the “sushi roll” pattern. Despite the name, this strategy has nothing to do with food—it actually originated during a discussion among traders over lunch about market patterns.
Key Takeaways:
- The sushi roll pattern is a technical formation that serves as an early warning system for possible trend reversals.
- If this pattern appears during a downtrend, it signals a potential buying opportunity or a chance to exit a short position.
- When it shows up in an uptrend, it warns traders to consider selling their long position or taking a short position.
- A test comparing the sushi roll strategy to a traditional buy-and-hold approach showed that traders using the sushi roll pattern achieved a return of 29.31%, whereas buy-and-hold investors gained only 10.66% over the same period.
Understanding the Sushi Roll Reversal Pattern
Fisher describes the sushi roll pattern as consisting of 10 consecutive price bars. The first five bars (inside bars) form a tight range of highs and lows, followed by the next five bars (outside bars) which engulf the previous five with both a higher high and a lower low.
This structure is somewhat similar to the bullish or bearish engulfing candlestick pattern, but it consists of multiple bars rather than just two.
When this pattern emerges during a downtrend, it suggests that the trend could soon reverse, offering traders a chance to buy or close short positions.
Conversely, if the pattern appears in an uptrend, it signals that the price might start falling, prompting traders to sell or initiate short trades.
While Fisher’s method suggests a five- or 10-bar pattern, the exact number isn’t fixed. Traders should experiment with different time frames and asset types to determine the most effective settings for their strategy.
The Outside Reversal Week Pattern
For traders with a longer-term approach, Fisher also introduces the “outside reversal week” pattern. This pattern operates on a weekly basis rather than daily bars.
It spans two weeks—starting on a Monday and ending on a Friday—where the first week’s price movements form a tight range, followed by a second week that engulfs the first with a higher high and a lower low.
Testing the Effectiveness of the Sushi Roll Reversal Strategy
To evaluate the reliability of the sushi roll pattern, a test was conducted on the NASDAQ Composite Index over a 14-year period from 1990 to 2004. An extended variation of the outside reversal week, known as the rolling inside/outside reversal (RIOR), was also tested.
Each pattern was identified using two back-to-back trading weeks, with the overall formation taking about four weeks to complete.
Trendlines were drawn to highlight dominant trends, while a rectangle was used to outline the two-week sections of the pattern.
In many cases, this pattern acted as a strong indicator of trend reversals, often followed by a confirmed trendline break.
After the formation of the pattern, traders could set stop-loss orders above the pattern for short trades and below the pattern for long trades. When comparing the performance of the RIOR strategy to a buy-and-hold approach:
- The buy-and-hold strategy delivered a return of 10.66% annually, earning 1,585 points over 14.1 years.
- Traders who followed the RIOR method entered their first trade on January 29, 1991, and exited their last trade on January 30, 2004. They executed 11 trades and were in the market for 1,977 days (7.9 years), or 55.4% of the time.
- This trading approach resulted in a total gain of 3,531.94 points—225% higher than the buy-and-hold strategy—with an annualized return of 29.31%, excluding commission costs.
Applying the Strategy with Weekly Data
A similar test was conducted using weekly data instead of daily data. Instead of 10-day periods, traders used 10-week patterns to identify reversals.
The study found that setting the first rectangle to 10 weeks and the second to eight weeks resulted in more effective sell signals than two five-week or two 10-week rectangles.
Over 14.1 years, the weekly strategy generated five signals and resulted in a profit of 2,923.77 points. The trader was active in the market for 381 weeks (7.3 years) out of the total 713.4 weeks, meaning they were trading 53% of the time.
The annualized return in this approach was 21.46%—making it a viable trading strategy, particularly when used alongside other indicators.
Confirming Trend Reversals
Regardless of whether traders use short-term (10-minute bars) or long-term (weekly bars) data, the tests confirmed that these reversal patterns performed well under various market conditions.
However, no trading strategy is foolproof when used in isolation. In technical analysis, confirmation from additional indicators is crucial to avoid false signals.
One of the most effective ways to confirm a reversal signal is through a trendline break. Additionally, traders can use the Relative Strength Index (RSI) to identify negative divergences, which often align with reversal points. Using stop-loss orders is also essential to manage risk in case a trade goes in the wrong direction.
The Bottom Line
Timing market entries at bottoms and exits at tops will always carry some risk. However, using proven techniques like the sushi roll pattern, outside reversal week, and rolling inside/outside reversal—especially in combination with confirmation tools—can significantly improve trading outcomes.
By incorporating these strategies, traders can enhance their ability to protect and grow their capital while navigating the complexities of market trends.
