Allow Me to Introduce Myself
One thing I want my clients to know about me is...
At QuantStreet, we use a systematic investment process that leverages modern statistical tools, combined with experienced human oversight. We focus on asset allocation and rigorous financial planning. We typically invest in low-cost, highly diversified, liquid ETFs. We also analyze alternative investments, like private equity, which we feel are appropriate for some clients. To learn more about our approach, see our monthly investor letter at www.quantstreetcapital.com/research-analysis.

Disclosures and Proof of License
Advisor Disclosure
AdvisorFinder is not a current client of QuantStreet Capital. AdvisorFinder receives cash compensation from QuantStreet for referring prospective clients. This arrangement creates a conflict of interest because AdvisorFinder has a financial incentive to recommend QuantStreet. QuantStreet pays AdvisorFinder $1,000 for each prospective client lead that AdvisorFinder provides, regardless of whether that person becomes a QuantStreet client. This compensation gives AdvisorFinder an incentive to generate referrals to QuantStreet and to favor QuantStreet over other qualified advisers that do not pay AdvisorFinder or pay AdvisorFinder less than QuantStreet pays.
AdvisorFinder Disclosure
AdvisorFinder ("AF") receives cash compensation from financial advisors in exchange for contact inquiries. AF is not an advisory client of any of the advisors it refers you to. AF has a conflict of interest because it has a financial incentive to refer you first to its paying customers (please click here for details). AF search results are conferred based on standardized and automated factors.
