Sell in May and go away? Maybe not

“Sell in May and go away” is a well-known market adage that warns investors to sell their equity holdings in May to avoid the typically volatile May-to-October period. Historically, stocks have underperformed in this six-month (“unfavourable”) period, compared to the six-month (“favourable”) period from November through April.

While the “Sell in May” strategy may sound tempting, in reality it may not be smart or practical. The performance during the unfavourable period, while lower than the favourable period, has been positive nonetheless. In a period of low interest rates, it would be ill-advised to forgo performance of nearly 1% (over the past 50 years).

Investors who can’t stomach the increased volatility during the unfavourable period but want to maintain equity exposure, may be better off considering a low-volatility strategy.

Since 1998, a low-volatility strategy could have outperformed the broad benchmark during the unfavourable period. This outperformance has ranged from 0.5% to 3.75% across different geographic markets.
