Which looks like the better buy

When comparing the Invesco Aerospace & Defense ETF (PPA) and the First Trust Indxx Aerospace & Defense ETF (MISL), investors should consider several key factors. Let's see what they tell us about each fund.

First, we should examine each fund's strategy. PPA focuses on traditional aerospace companies and industrial military suppliers. It is a more established fund with a history dating back over 20 years and more than $7.2 billion in AUM. MISL, on the other hand, is a more recent entrant. The fund was established in 2022 and has a more modern defense-tech strategy. For example, its largest holding is Palantir, followed by SpaceX.

Two other important factors are historical performance and income potential. Since 2022, PPA has generated a total return of 117%, equating to a compound annual growth rate (CAGR) of 21.6%. MISL, meanwhile, has delivered a total return of 105%, with a CAGR of 19.8%. PPA has modestly surpassed the S&P 500's return over this period; MISL has fallen just short of it. Neither fund is a significant dividend payer, although PPA offers a slightly higher yield at 0.4% versus 0.1% for MISL.

One final factor to weigh is cost. Both funds have room for improvement in their fees. PPA has an expense ratio of 0.58%, while MISL has an expense ratio of 0.60%. Both of these rates are slightly above the average ETF expense ratio and far beyond what most investors will pay for index ETFs. For context, a person who buys $10,000 of PPA and MISL should expect to pay $58 in annual fees for their PPA shares and $60 for their MISL shares.

In summary, PPA and MISL are both ETFs built around aerospace stocks, however, they vary in significant ways. In the head-to-head matchup, PPA comes out on top in several factors, including historical performance, yield, and cost. Therefore, some investors may elect PPA. Yet, given MISL's forward-looking approach and significant stakes in SpaceX and Palantir, more aggressive investors may prefer MISL to its more conservative counterpart.
