Precious metals and gold dominated the ETF landscape last year—no shock there. Yet what's really catching attention are the lesser-known products that are quietly skyrocketing. While headline players grabbed the spotlight, these under-the-radar performers delivered some serious moves. Investors hunting for portfolio diversification beyond the usual suspects are finding genuine opportunities in niche ETF categories. The data tells an interesting story: as traditional safe havens stabilized, alternative exchange-traded products started flexing serious upside. Worth keeping tabs on this shift if you're building positions across different asset classes.
