Briefcase direct indexing can be a way for advisors to give clients a strategy that accomplishes their financial goals in the long term, is tax aware, and aligns their investments with personal values and situation.
“My Briefcase Direct Index Portfolio, which excludes major positions I already own, is tracking the index very well. It has also demonstrated lower volatility than the benchmark.”

“The Australian equity Direct Index portfolio has been great for my cancer foundation client, upon realising the existing ESG ETF they were invested in held tobacco stocks, we needed to move to a Briefcase solution.”
Independent Advisor
“My existing equity portfolio has underperformed the index by 1.5%p.a. since 2012. My broker also charged me double the fee when compared with Briefcase. If Briefcase had existed in 2012, my portfolio would be $400,000 better off.”
