As sector ETFs have proliferated, more and more investors have been attracted to sector rotation and tactical asset allocation strategies using ETFs, whether self-managed or implemented by an advisor. Mark Hulbert commented on sector rotation strategies in a recent article on Marketwatch that highlighted newsletters using Fidelity sector funds. All of the newsletters had good returns, but there was one surprising twist:
…you might think that these advisers each recommended more or less the same basket of funds. But you would be wrong. In fact, more often than not, each of these advisers has tended to recommend funds that are not recommended by any other of the top five sector strategies.
That’s amazing, since there are only 44 actively managed Fidelity sector funds and these advisers’ model portfolios hold an average of between five and 10 funds each.
This suggests that there is more than one way of playing the sector rotation game, which is good news. If there were only one profitable sector strategy, it would quickly become so overused as to stop working.
This is even true among those advisers who recommend sectors based on their relative strength or momentum. Because there are so many ways of defining these characteristics, two different sector momentum strategies will often end up recommending two different Fidelity sector funds.
Another way of appreciating the divergent recommendations of these top performing advisers is this: Of the 44 actively managed sector funds that Fidelity currently offers, no fewer than 22 are recommended by at least one of these top five advisers. That’s one of every two, on average, which hardly seems very selective on the advisers’ part.
Amazing, isn’t it? It just shows that there are many ways to skin a cat.
Even with a very limited menu of Fidelity sector funds, there was surprisingly little overlap. Imagine how little overlap there would be within the ETF universe, which is much, much larger! In short, you can safely pursue a sector rotation strategy (and, by extension, tactical asset allocation) with little concern that everyone else will be plowing into the same ETFs.
