GMO, co-founded by prominent value investor Jeremy Grantham, has recently introduced a new actively managed investment strategy through the GMO Dynamic Allocation ETF (GMOD). This initiative is grounded in the belief that all asset classes will eventually revert to their historical means, a philosophy deeply embedded in Grantham’s investment ideology.
John Thorndike, the co-head of asset allocation at GMO, emphasized the importance of caution without inciting panic among investors. He articulated that while current market valuations are a source of concern, they warrant vigilance rather than alarm. “High valuations offer both lower expected returns and higher risk than fairly valued or cheap markets,” Thorndike explained in an interview. He noted that while valuation may not reliably predict short-term market movements, an overvalued market could easily decline amidst investor apprehension.
To mitigate valuation concerns, GMO has designed GMOD to pivot towards asset classes with more favorable valuations and growth forecasts. Launched in October, this fund’s strategy reflects a proactive approach to capital allocation, enhancing the potential for maximizing returns over the long term.
An analysis revealed a bleak outlook for U.S. large- and small-cap stocks, projected to yield negative returns by the end of September, which has influenced the fund’s current positioning favoring global asset allocations outside of the U.S.
Thorndike pointed out that optimal asset allocation is crucial for achieving investment success, with the traditional 60/40 portfolio serving as a common starting point. Currently, GMOD maintains a distribution of about 60% in stocks and 40% in bonds, favoring quality and value stocks, particularly in Japan and emerging markets.
During an interview, Thorndike elaborated on GMO’s current market perspective, stating, “This market isn’t like 2007 or 2008 when everything was overpriced, and you needed to hide out in the safest assets. Today, you can be fully invested by simply avoiding the costliest sectors.” He highlighted the comparative value in U.S. stocks trading at significant discounts relative to their growth counterparts.
Thorndike pointed to the impressive performance of key stocks known informally as the “Magnificent Six,” noting their evolving business strategies that now involve substantial capital investment, a shift from their previous models that relied heavily on free cash flow.
Regarding bond allocations amid potential Federal Reserve rate changes, Thorndike noted that their strategy has not drastically shifted in response to interest rate expectations. Instead, they focus on the bond market’s capacity to generate income and provide resilience in economic downturns.
When asked about geographical investment opportunities, Thorndike underscored Japan as a particularly undervalued market, taking advantage of improving company returns and beneficial policies aimed at enhancing shareholder value. He posited that the current valuation of the U.S. dollar also plays a pivotal role in making non-U.S. stocks more enticing.
In the event of a significant decline in U.S. equity markets, Thorndike suggested that GMOD would retain flexibility to recalibrate its allocations. Although he refrained from making predictions, he acknowledged that a downturn could create opportunities to recalibrate around undervalued equities, stressing the fund’s strategy to buy low and sell high.
As investors navigate the complexities of the current market landscape, GMO’s insights provide an alternative framework for approaching asset allocation, emphasizing caution while remaining fully engaged in promising sectors beyond traditional growth stocks.
