Week 12 Day 4: The Cash Bucket Strategy

If you need $50,000/year, keep $100,000-$150,000 in cash or short-term bonds. When the market drops, you live off the cash bucket instead of selling stocks at depressed prices. This gives the stock portfolio time to recover without being forced to sell low.

The bucket strategy divides your portfolio into three buckets. Bucket 1 (Cash): 1-3 years of expenses in high-yield savings or money market. This is your spending money. Bucket 2 (Bonds): 3-7 years of expenses in intermediate-term bonds. This is your stability buffer. Bucket 3 (Stocks): Everything else in equities for long-term growth. This is your growth engine. In normal years, you replenish Bucket 1 from investment returns or by selling from Bucket 2 or 3. In bad years, you spend from Bucket 1 without selling any stocks. This prevents the sequence-of-returns problem: you are never forced to sell equities at the worst possible time. The psychological benefit is equally important: knowing you have 2-3 years of cash makes it emotionally possible to ride out a crash without panicking.

The bucket strategy, popularized by Harold Evensky in the 1980s and refined by Christine Benz at Morningstar, has mixed academic support. Research by Estrada (2020) found that the bucket approach does not mathematically outperform a simple systematic withdrawal from a balanced portfolio in terms of expected terminal wealth. However, it significantly outperforms in terms of worst-case outcomes and behavioral adherence. The cash buffer reduces the probability of selling equities during drawdowns, which is the primary mechanism of SOR risk. More importantly, the psychological framing -- 'I have 3 years of cash, I do not need to worry about the market' -- dramatically reduces the likelihood of panic selling, which DALBAR data shows is the single most destructive investor behavior. The Evensky/Benz framework recommends replenishing the cash bucket opportunistically (during strong market years) rather than on a fixed schedule, which introduces mild market-timing benefits while maintaining the core behavioral protection.
