Fidelity Health Savings Fund - Class K 

This fund's main objective is to help investors save and build capital specifically for future eligible healthcare costs. It achieves this by primarily investing in a diverse mix of underlying assets, which include both actively managed and passively tracked Fidelity bond and equity funds, as well as exchange-traded funds (ETFs) from both internal and external providers. The portfolio is generally structured with an approximate allocation of 30% towards equity-focused underlying funds and roughly 70% towards bond-focused underlying funds.
