I just discovered this ETF a couple weeks ago. It uses relative sentiment indicators, and US interest rates, to determine its allocations every week. Seems to typically be a mix of developing market ETFs, gold, and TIPS bonds. Its performance since inception about 3 and half years ago seems to be remarkably consistent, and far over performing the market. It has a high expense ratio, but since it does so well that doesn't seem to matter. It appears to me to be a good ETF to own in any market condition, good or bad. Even back in April of last year when it seemed like everything crashed, it barely dipped and quickly rebounded after the next reallocation.
So my question is, is there a reason I'm not seeing that explains why more people aren't buying it? Is there something about how it works that makes it a high risk at some point in the near future? What am I overlooking?
Here's a link with more info on it:
