Thematic ETFs Are Finally Gaining Some Much-Needed Respect

 | Sep 27, 2017 12:38AM ET

Thematic funds have long been one of the more dubious areas of the ETF industry. In a broad sense, this genre is all about taking an investment concept with potentially long-term, cyclical implications and finding a group of stocks that fit the criteria. It’s more about investing in a story rather than identifying companies based on strict fundamentals or sector prowess.

Want to invest in the trend of weight loss, clean energy, or social media growth? There are now multiple funds to choose from in each category.

Thinking that you want your portfolio positioned according to your political, religious, or ethical beliefs? I can easily point you in the right direction with several options to choose from.

It’s been an industry-wide trend that most ETFs released along these lines are quickly relegated to near-obscurity. They are often launched with minimal backing, little daily trading volume, and the uncertainty that comes with holding just a handful of stocks in a narrow vertical. Most come with significantly higher fees than a broad-based index from the likes of Vanguard or Blackrock (NYSE:BLK) as well.

Nevertheless, with ETFs becoming more mainstream and investors adopting them in droves, the comfort level of thematic trends has increased in recent years. Primarily among funds that are experiencing top-tier growth in their performance metrics to drive substantial asset flows. Money chasing performance is perhaps the oldest principle of investment psychology.

One of the original success stories of thematic funds can be attributed to the PureFunds ISE Cyber Security (NYSE:HACK), which grew from relative anonymity to over $1.1 billion in assets. This growth was attributable to multiple high-profile internet security lapses that allowed investors to visualize the development opportunity for companies within this industry.
