Do You Really Need Bond ETFs Before Age 50? Here's What I'd Do.

The traditional investment approach suggests that a portfolio should become more conservative as an individual ages, shifting away from a 100% stock allocation and towards a larger bond allocation. However, for someone with over 10 years until retirement, is it truly necessary to include bonds in the portfolio? Missed an opportunity with Nvidia in 2009?

This intriguing signal is resurfacing again. In 2009, a Double Down signal emerged for Nvidia, a relatively unknown chipmaker. Now, a Total Conviction signal is flashing for a company one-hundredth the size of Nvidia. While adding a bond ETF to an all-equity portfolio can reduce overall volatility, it also comes at the cost of potential long-term returns.

Over extended periods, this could result in significant financial losses. Let's examine the Vanguard Total Bond Market ETF (NASDAQ: BND) as a representative of the entire bond market, which includes investment-grade corporate and government bonds. Currently, this ETF yields around 4.7%, indicating that fixed income can indeed be a viable asset class to consider.

However, bonds are not a substitute for equities; their primary purpose is to offer stability and risk-reducing diversification benefits. For someone in retirement who prioritizes principal protection over capital growth, this is crucial. Yet, even a modest shift from a 100% stock/0% bond allocation to a 90% stock/10% bond split can have consequences.

Assuming a 5% annual return for the Vanguard Total Bond Market ETF, this change could result in a 0.5% annual return loss with minimal risk reduction. The impact grows exponentially with larger shifts. Moreover, age should not be the sole determining factor for bond allocation. Various factors, such as the number of working years remaining, income requirements, spending plans, current savings, and risk tolerance, should be considered.

For equities, the Vanguard Total Stock Market ETF (NYSEMKT: VTI) could be the core of the portfolio. If the volatility of a 100% equity portfolio is a concern, one could gradually shift a portion of the portfolio into the Vanguard Total Bond Market ETF to mitigate volatility. The optimal time to consider adding bonds might be five to ten years before retirement.

At this stage, minimizing downside risk becomes the primary concern. If an individual has more than ten years until retirement, a substantial bond allocation may not be necessary unless their risk tolerance warrants it.
