RTH provides a different yet comprehensive take on retailers. The fund's claim of global scope is limited by its objective of only investing in companies also listed in the United States. RTH began tracking a new, capped index in December 2011, but still retains the concentrated exposure typical of its HOLDRS roots. Investors looking for exposure to global retailers will find concentrated exposure to US retail giants that dominate worldwide. The fund's exposure makes it less risky than our global benchmark, making RTH a relatively safe place to get exposure to the retail space. The index is reviewed semi-annually.
