CAD/CHF Posts -1.32% Avg Return in December, 20-Year Data

Monthly Bias Map

When examining the CAD/CHF currency pair over a 20-year dataset, certain months stand out for their distinct seasonal patterns. April emerges as a strong month, with an average return of +0.96% and a win-rate of 70%. Conversely, December has historically been weaker, with an average return of -1.32% and a win-rate of just 35%.

The current month, September, typically offers a modest positive bias with an average return of +0.45% and a win-rate of 60%. This historical context can provide a probabilistic framework for traders, though it's crucial to understand the underlying reasons and limitations of these patterns.

Best and Worst Months

April: The Best Month

April's positive performance could be attributed to several factors. In the foreign exchange market, April often coincides with the end of the fiscal year for many countries, including Canada. This period can lead to increased hedging activities and financial flows that favor the Canadian dollar. Additionally, April's high win-rate of 70% suggests a consistent seasonal bias that traders might consider as part of their broader strategy.

December: The Worst Month

December, on the other hand, is characterized by a notable negative return, averaging -1.32%. This could be linked to end-of-year portfolio adjustments and tax-loss selling, where investors might be closing positions for tax purposes, potentially exerting downward pressure on the currency pair. The low win-rate of 35% further underscores the challenges of trading CAD/CHF in December.

Day-of-Week Tilts

Examining the day-of-week data, no significant positive biases emerge. Fridays show an average return of -0.038% with a win-rate of 37%, while Wednesdays and Thursdays have similarly low win-rates of 35% and 28%, respectively. This suggests that weekly trading patterns are less pronounced for CAD/CHF, highlighting the importance of focusing on monthly trends.

Where Seasonality Breaks

While seasonal patterns provide valuable probabilistic insights, they are not infallible. Macroeconomic shocks, such as unexpected interest rate changes or geopolitical events, can disrupt established patterns. Additionally, changes in market structure or economic regimes can alter historical relationships, making past data less predictive.

Where This Fits

Seasonality can offer a useful lens through which to view market tendencies, but it should be one of many tools in a trader's toolkit.
