A Period of Typical Seasonal Weakness Nears
Key points:
- Seasonality is generally best used as an "alert of possibilities" rather than as a specific market timing signal
- That said, certain tendencies that span across a variety of sectors and indexes can serve as valuable clues
- A period of typical weakness for a variety of indexes and sectors is almost upon us
Seasonality as a Trading Tool
For my own purpose, I typically use seasonality as a tool to tell me, "When to look where." In other words, I look at seasonal tendencies to highlight potential opportunities rather than trigger specific trades. In most cases, I like to see price action in line with a given seasonal tendency before entering a position. However, there are certain times when a wide array of markets and/or sectors show the same tendency. These can be good times for traders to look for countertrend opportunities, and for longer-term investors to consider hedging their portfolio, whether by raising cash or hedging - possibly via the use of options.
The late February to mid-to-late March period has a history of market weakness. We highlight some specific indices and sectors below.

What the research tells us…
The table below summarizes the information above.

Remember that the dates listed in the table above should not be considered "automatic" buy or sell dates, but rather periods when investors should be prepared for weakness, and traders might consider playing the short side (either selling short shares or trading options).
As always, seasonality is ultimately a look back at what has happened in the past, not a roadmap for what will happen in the future. As a result, traders must remember that even the most historically persistent seasonal trend can fail the next time around. With those thoughts in mind, longer-term investors must carefully consider whether they wish to hold a long position in the sectors and markets highlighted above. Historical probabilities suggest diminished short-term expectations. Likewise, shorter-term traders must decide if they are willing to assume the risk of a counter-trend position, as most of the underlying markets/sectors highlighted above are presently in established uptrends. In any event, regardless of the setup that triggers any trade, a trader is never relieved of their responsibility to a) intelligently allocate capital (i.e., never "bet the ranch"), and b) ruthlessly manage risk.
