The document discusses the importance of lower volatility investments for those drawing down income from their portfolios. It notes that the trade-off between risk and return is crucial, as investments need to provide adequate income without depleting capital too quickly or experiencing severe losses during market declines. Lower volatility protects portfolios more during downturns, as illustrated by an example where a 20% decline requires a smaller 25% recovery than a 50% decline needing a 100% bounce back to break even. Overall, the document advocates for lower risk investments to safeguard against large losses for those relying on portfolio withdrawals for income.
