DWS Global Thematic overcomes quirky names and high turnover.
Most stock-fund portfolio managers invest by choosing companies individually, based on their specific characteristics. At least that's the part of their strategy they emphasize. It's quite unusual to find stock-fund managers saying they try to beat the pack with a theme-based approach that puts as much or more emphasis on identifying broad trends as on simply digging up attractive individual companies one by one.
In general, that might be a good thing. Managers who base their strategy on themes might pick correct trends but falter anyway because the companies they chose had shortcomings that limited their ability to benefit from favorable tailwinds. For example, a few years ago many managers were buying big drug companies because the aging of populations would ostensibly make those firms indispensable. (That didn't work out well, for the most part.)
Another red flag for a fund strategy can be if its strategy sounds gimmicky, with names that seem like they could've been dreamed up by the marketing department rather than an investor.
However, some stock funds do talk about incorporating theme investing into their thinking. Those that have succeeded with this approach tend to choose themes that lie outside the mainstream, and to still pay close attention to individual company traits rather than just picking essentially any stock that fits one of the themes. One such fund that has enjoyed much success with such a method, in the few years since its current manager took over, is DWS Global Thematic
Don't Worry About the Names
Oliver Kratz, who has managed this fund since autumn 2003, invests with 12 broad themes in mind. Some of them sound odd enough that they could scare off skeptical and sophisticated investors who are well aware of the dismal record of funds with overly trendy names or overly complex strategies. One of this fund's themes is called "Talent & Ingenuity"; another is "Asymmetric Negotiators." But those aren't as strange, or as complicated, as they may sound. The former refers to companies that gain their advantage through intellectual prowess and creativity, such as Apple
Companies from the same sector can be found listed under different themes. That freedom could trip up a manager. The themes could end up being simply a gloss, with the manager actually just picking stocks the conventional way and only later finding a theme to shove them under.
Kratz, though, has made this strategy work. The fund has trounced the world-stock category since he took over, even though it had a subpar 2007, when he saw better opportunities in areas other than energy. That ended up hurting the fund in relative terms as energy stocks climbed and climbed. (The fund's relative performance looks much better so far in 2008.)
He has overcome the potential pitfalls partly by choosing the right themes--but also by succeeding on the company level. The fund could've been crushed if he had bought many more banks and insurers simply because they could fit under one or another theme. But he steered clear of most of the ones that got hit hard by the credit crisis brought on by subprime-mortgage issues.
