WisdomTree WAMA ETF uses 200-day SMA to shift to T-bills

The WisdomTree U.S. Adaptive Moving Average Fund (WAMA) began trading March 12. The ETF tracks the WisdomTree U.S. Adaptive Moving Average Index and uses a 200-day simple moving average to allocate between U.S. equities and Treasury bills. When the index’s moving average indicates an upward trend, WAMA increases its stock exposure; when the moving average turns negative, the ETF raises its allocation to T-bills.

Fund documents state the strategy emphasizes a long-term 200-day simple moving average rather than shorter-term averages. The 200-day SMA is described as producing a smoother trend line and reducing the number of short-term signals that can trigger frequent allocation changes. The index’s observed moving average determines target allocations at scheduled rebalancing dates.

Technical practitioners use moving averages to compare current prices with historical averages and to identify possible support or resistance levels. Approaching or crossing a moving average is commonly treated as a point where price may pause or retrace; longer moving averages typically generate fewer false signals than shorter ones.

WisdomTree has also listed an international counterpart, the WisdomTree International Adaptive Moving Average Fund (WIMA), which applies the same adaptive moving-average approach to non-U.S. equities. The funds automate the moving-average calculation and signal monitoring that advisors and investors would otherwise perform themselves.

The WAMA launch follows investor interest in rules-based strategies that alter exposure between equities and short-term cash instruments based on objective trend indicators.
