Emerging equities have continued to underperform developed markets so far in 2013 but relative monetary trends and valuations suggest an imminent turnaround.

The first chart shows the ratio of MSCI’s emerging equity markets index to its developed markets index – a rise in the line indicates that emerging equities are outperforming and vice versa. This ratio is compared with real (i.e. inflation-adjusted) money supply growth in the Group of Seven (G7) major countries and seven large emerging economies – the “E7”*.

Monetary strength signals favourable economic prospects and liquidity support for markets. The chart shows a relationship between the relative performance of emerging equities and the gap between E7 and G7 real money growth. The index ratio peaked in late 2010 as the gap narrowed sharply, turning negative in early 2011. The glory days of emerging equities in 2009-10 and before the financial crisis, by contrast, occurred against the backdrop of relative monetary buoyancy.

An update in February suggested remaining cautious on emerging markets because E7 real money growth, while improving, had not yet crossed above G7 expansion. Emerging equities have since underperformed by a further 7% but the awaited cross-over has now occurred, based on March money supply data. Monetary trends have strengthened in most of the E7 countries and there have been similar or larger gains in smaller emerging economies not included in the aggregate.

Emerging markets, meanwhile, appear inexpensive: the price to earnings ratio based on forecast earnings over the next 12 months is 10.1 versus 13.2 for developed markets, according to I/B/E/S – second chart. The 23% discount is the largest since 2006.

*The E7 is defined here as BRIC (Brazil, Russia, India, China) plus Korea, Mexico and Taiwan.
