Launched on 12/08/2014, the iShares MSCI ACWI Low Carbon Target ETF (CRBN Quick QuoteCRBN - Free Report) is a smart beta exchange traded fund offering broad exposure to the World ETFs category of the market.

What Are Smart Beta ETFs?

Products that are based on market cap weighted indexes, which are strategies designed to reflect a specific market segment or the market as a whole, have traditionally dominated the ETF industry.

Market cap weighted indexes offer a low-cost, convenient, and transparent way of replicating market returns, and are a good option for investors who believe in market efficiency.

If you're the kind of investor who would rather try and beat the market through good stock selection, then smart beta funds are your best choice; this fund class is known for tracking non-cap weighted strategies.

This kind of index follows this same mindset, as it attempts to pick stocks that have better chances of risk-return performance; non-cap weighted strategies base selection on certain fundamental characteristics, or a mix of such characteristics.

While this space offers a number of choices to investors, including simplest equal-weighting, fundamental weighting and volatility/momentum based weighting methodologies, not all these strategies have been able to deliver superior results.

Fund Sponsor & Index

The fund is sponsored by Blackrock. It has amassed assets over $1.03 billion, making it one of the larger ETFs in the World ETFs. CRBN seeks to match the performance of the MSCI ACWI Low Carbon Target Index before fees and expenses.
