With $439 million to play with Ross Asset Management (RAM) would be one of New Zealand's largest boutique fund managers and perhaps the biggest in what is understood to be its chosen asset class of global equities.
The only drawback to this argument is Ross Asset Management, currently under investigation by the Financial Markets Authority (FMA), is not a funds manager, at least in the traditional retail sense.
As RAM doesn't offer any formal retail fund it's therefore not subject to all the messy, expensive compliance duties other less-exclusive operations must adhere to such as: issuing a prospectus and investment statement; setting up a corporate trustee structure, or; using an independent custodian to ensure all transactions are carried out correctly.
In short, all that boring back-office process that retail investors choose to ignore (but can nevertheless read about in publicly available documents) is even more of a mystery in an operation like RAM.
According to the Financial Services Providers Register, Ross Asset Management is in the business of: Keeping, investing, administering, or managing money, securities, or investment portfolios on behalf of other persons.
