27 y/o male, plan to retire @ 60. Boglehead/JL Collins inspired, 100% hands off, buy and hold portfolio. DCA every 2 weeks. Max tax advantaged accounts, leftover goes to brokerage. Follow the global weighting of US to International(currently 63% US, 37% Int). Dividends set to auto reinvest. Will add bonds slowly once i hit around 50 years old. Goal is to check portfolio once a year, reallocate if necessary, and go enjoy life/focus on career. Cash sitting in HYSA. Thoughts? Concerns?
