Retirees: Avoid Overweighting AI Stocks; Maximize Social Security at 70 (NVDA, GOOGL)

Retirees planning to reach full retirement in 2026 should actively rebalance portfolios to counter AI-driven stock concentration, avoiding overexposure to companies like Nvidia (NVDA) and Google (GOOGL). Bull markets often outpace rebalancing intentions, leading to unintended risk exposure. Key actions: Delay Social Security until as close to age 70 as possible to maximize benefits; consider staying in the workforce longer to grow retirement savings and maintain contributions. In the event of early retirement market downturns, prioritize cash reserves and reduce initial withdrawal rates under a modified 4% rule to avoid selling at a loss. Also, cover essential expenses with a mix of Social Security and guaranteed income sources like pensions or annuities. Contrary to outdated rules of thumb, retirees often spend more in the years around retirement, particularly on discretionary items, so budgeting for lifestyle changes is critical.
