The reason behind some differences in ETF information on our platform and the issuer's website is a combination of latency in receiving updates from the issuer and differences in the ways of classifying the sectors.
The issuer chooses how frequently they send us updates on the ETF. It is usually anywhere between every 5 and 15 working days. Once the information is received it is updated instantly on our platform.
The way we classify holdings is using the MSCI definitions, which can be found here and here. Unfortunately, there is no single industry standard, and while MSCI is used by most retail providers, other issuers may have varying approaches.
When researching an ETF online, please make sure that the ticker and the full name always match. Some indexes may be tracked by several issuers with a variety of extra features. Similarly, ETFs traded on different stock exchanges may have different tracking as well. It is important to be sure that the information you find online applies to the exact ETF in your portfolio.
