This is a thematic ETF that tracks a dedicated cloud computing index and invests in cloud infrastructure, software, and services companies. It includes not only pure-play cloud companies but also large technology companies with a high share of revenue from the cloud.

It suits investors who want to bet directly on the growth of the cloud computing industry.

It is a passively managed (index-tracking) ETF launched by First Trust in 2011.

The fund classifies cloud computing companies into three categories, SaaS, PaaS, and IaaS, and holds them in a diversified manner. By combining pure cloud companies with established large technology companies that are in the midst of a cloud transition, it provides even exposure across the industry.

• Tracks a dedicated cloud computing index to maintain thematic focus
• Balanced allocation across the three categories of SaaS, PaaS, and IaaS

Assets under management (AUM) are $3.5B, and the expense ratio is 0.60% per year.

It is one of the earliest products launched among cloud computing theme ETFs. Its fees are somewhat higher than those of similar-category ETFs, but its thematic specialization and long track record are distinguishing features.

Rising demand for cloud migration and the expansion of artificial intelligence infrastructure have combined to sustain improving earnings at cloud-related companies. Depending on the interest rate environment, there are also periods when volatility rises in a portfolio centered on growth stocks.

As the spread of artificial intelligence drives greater investment in cloud infrastructure, interest in fund inflows into related theme ETFs is growing. However, the fund tends to be corrected along with large technology stocks when their valuations adjust.

Its strengths are its concentration in the cloud theme and its exposure to a variety of cloud business models, while its weaknesses are its fee level and the volatility that comes with a concentration in technology stocks.

Among the products shown in the table, ONEQ is a broad ETF based on the Nasdaq Composite Index that covers technology stocks well beyond the cloud, while VFH is a financial sector ETF and VIS is an industrial sector ETF, so their investment direction differs from SKYY. IYF is likewise centered on the financial sector and differs in character from the cloud theme. Alternatives that approach cloud and technology themes like SKYY more broadly include XLK, which covers the technology sector as a whole, and FDN, which focuses on internet and software. For a narrower focus on cloud infrastructure, CLOU can also be considered.

These are the points to review before investing in SKYY. Because the fund is concentrated in a single cloud theme, it is important to understand its sector concentration, fee level, and volatility characteristics in advance and to confirm that it fits your investment objectives.

Because the fund is concentrated in a single cloud theme, volatility can increase when the broader market corrects. In a rising interest rate environment, valuation pressure can accompany it given the nature of growth stocks, and the fee burden should also be considered for long-term investment.

It is a thematic ETF suited to investors who want concentrated exposure to the cloud computing industry as a whole. Given its somewhat high fees, it is advisable to compare it with lower-cost, broad technology ETFs (such as XLK) before making a choice.
