SILJ is a thematic ETF that holds small- and mid-cap silver mining and exploration companies around the world, weighted by their share of revenue from silver. It tracks the Nasdaq Junior Silver Miners Index and includes both producing and exploration-stage companies.

It suits aggressive investors who expect higher returns than SIL when silver prices rise and who can tolerate high volatility.

It is a passive (index-tracking) ETF launched in 2012 by Amplify ETFs.

The fund overweights pure-play silver mining and exploration companies based on their share of silver revenue. Because it is built around small- and mid-cap junior companies, it seeks more leveraged exposure to silver prices than SIL, which holds large miners.

• Its concentration in small and exploration-stage companies offers the potential for larger gains than large-cap mining ETFs such as SIL and GDX when silver prices rise
• Weighting by silver revenue share keeps the thematic purity of a focus on pure silver miners
• Launched in 2012, it has one of the longer track records among ETFs specializing in small silver miners

Assets under management (AUM) stand at $3.2B, and the expense ratio is 0.69% per year.

SILJ belongs to the group of precious metals and commodity mining ETFs that includes GDX, GDXJ, SIL, COPX, and URA. GDX is an ETF of large gold miners, while GDXJ is an ETF of small gold miners, with a small-cap structure similar to SILJ but focused on gold. SIL centers on large silver miners and has lower volatility and stronger financial stability than SILJ. COPX covers copper mining and URA covers uranium mining, both different commodities from silver. For investors who want high-beta exposure to the direction of silver prices, SILJ is the more aggressive choice compared with SIL.

As expectations of rising silver prices and growing industrial silver demand converge, interest in small silver mining and exploration companies is increasing, and SILJ continues to attract inflows as a vehicle for betting on higher silver prices.

When precious metals rally, aggressive investors seeking higher returns than large mining ETFs such as SIL and GDX tend to shift toward SILJ and GDXJ.

SILJ is a small- and mid-cap silver mining and exploration ETF for investors who want high-beta exposure to rising silver prices. It offers higher return potential than SIL, but with higher volatility.

To invest in silver mining with lower volatility, SIL, which centers on large silver miners, is a better fit. For exposure to small gold miners, consider GDXJ, and for large gold miners, compare GDX. For other commodities such as copper and uranium, COPX and URA are the specialized options.

SILJ is a small silver mining and exploration ETF for investors who want to make an aggressive bet on rising silver prices. Understand its high volatility and exploration risk, then approach it with a small satellite position.

Because of the nature of small and exploration-stage companies, losses can be larger than with SIL or GDX when silver prices fall, and there is also the risk of business failure at exploration-stage companies. Limited small-cap liquidity can make trading costs high, so caution is needed with short-term trading.

SILJ is a small silver mining and exploration ETF suited to aggressive investors who want high-beta exposure to rising silver prices. Compare its volatility and risk tolerance against SIL, and consider a small satellite position within your portfolio.
