We examine wealth outcomes and risk of ruin faced by retirees due to persistent bad re-
turns and high volatility in equity markets occurring at different stages of their retirement.
Our results show poor equity returns persisting over long periods can put retirement se-
curity to serious risk but volatile market conditions actually have the opposite impact. The
timing of such persistent bad returns and volatility (early or late stages of retirement) is
critical and has differing effects on retirement outcomes. The results are robust to varying
portfolio allocations to equities although the precise impacts are different.

1. Introduction
Retirees are often advised to adopt a ‘safety first’ approach to ensure their nest eggs are able to provide a steady source
of income over their lifetime. However, a general consensus has emerged that holding some equities in the retired investor’s
portfolio is essential to generate adequate income to fund a comfortable retirement and minimise the risk of outliving
their assets. For example, Bengen (1994; 1997) recommends a portfolio allocation of 50% to 75% to equities to allow for
a sustainable retirement. Others like Cooley, Hubbard, and Walz (1999) find that a portfolio with 75% allocated in stocks
and the rest allocated in corporate bonds can sustain 4–5% inflation adjusted annual withdrawals. More recent studies like
Bewley et al. (2007) suggests that, due to ever increasing life expectancy, sustaining over longer periods in retirement makes
the case for allocating to equities stronger for investors till they get to the late stages of retirement.
Holding equities in retirement can benefit the retiree’s portfolio by harvesting the equity premium historically observed
over long horizons. Indeed, Cooley et al. (2003) suggest that most retirees allocate between 25% and 75% of their retirement
portfolio to equities. Yet this allocation strategy carries significant risk of depletion of retirement savings in the event of
