Abstract
This research examines the consumer
exchange-traded funds (ETFs) in several industries based on long memory and
multiple structural breaks. The autoregressive fractionally integrated moving
average (ARFIMA) model indicates that consumer ETF returns in the media,
consumer service, food and beverage, and consumer goods industries can be
accurately predicted. The autoregressive fractionally integrated moving average
and fractionally integrated generalized autoregressive conditional
heteroskedasticity (ARFIMA-FIGARCH) model reveals that only the gaming and
consumer goods industries have a long memory in volatility. This study
establishes that through the iterated cumulative sum square test, multiple
structural breaks exist in consumer ETF industries. Results prove that the
consumer goods industry has a long memory and multiple structural breaks.
Finally, the structural breaks in consumer ETFs have strong asymmetrical
effects, indicating that all of the consumer ETF industries are generally
unstable.
