It makes sense to ask whether stocks can add to the double-digit gains they have delivered so far this year in the face of a steady increase in government bond yields.
Rising yields lead to higher commercial borrowing costs and also reduce the present value of future corporate earnings, developments that normally weigh on equity markets. But concerns surrounding the sustainability of the stock rally look overdone, in our view.
There are strong reasons to believe equities will continue to rise over the next few months. The main argument for maintaining our overweight stance on stocks comes down to corporate profitability. Earnings are still growing at a remarkable pace, thanks in part to the broadening adoption of new technologies such as AI. According to analysts’ consensus forecasts, company profits are set to grow 30% this year; we believe they could increase at an even faster rate, by some 35%.
Also in stocks’ favour are economic conditions.
While the rise in bond yields can be partly attributed to a build-up in inflationary pressures and stubbornly high public-sector deficits, it is also the case that fixed-income markets are discounting reasonably healthy levels of economic growth. Indeed, as history shows, rising bond yields aren’t always associated with declines in equity markets. It all depends on why yields are rising in the first place. When bonds sold off during periods when the economy was performing well, as was the case in both 1994 and 2013, equity markets did not suffer declines.
The same picture appears to be emerging today. Our business cycle indicators show that, save for a deterioration in China’s consumption spending, the economic picture remains relatively positive. Europe’s economy, for example, is performing better than most envisaged at the beginning of the Iran conflict. Consumer spending and business investment are both rising, while inflationary pressures are easing.
And while the US has seen consumer spending growth slow to an annual 1.8% in recent months, below its long-term rate of 2.5%, increases in capital investment are more than offsetting this slowdown.
Emerging markets are also on a sound economic footing, benefiting from high commodity prices, strong export growth, and relatively low interest rates. True, China is a concern: domestic consumption is weakening and the property market is struggling. But overall, our analysis gives positive signals for the global economy. Indeed, the economic surprises index, which tracks the extent to which data surpasses or undershoots consensus forecasts, has remained in positive territory since the tail end of 2025.
Valuations also support maintaining a higher allocation to equities. One indicator we attach great importance to is the equity risk premium, or the discount investors demand for buying riskier stocks over government bonds. Our analysis, shown in Fig. 2 and comparing stocks’ earnings yields to US Treasury yields, illustrates that the discount, while low, remains some distance from the level that would suggest stocks are vulnerable. Treasury yields would have to rise substantially for that to be the case.

Elsewhere, the technical indicators we monitor are positive for stocks but less so for bonds. Although September tends to be a challenging month for stocks, surveys showing investors don’t hold excessively bullish positions in equities are a positive sign.
While economic indicators, valuations and technical indicators are positive for riskier assets, liquidity is in shorter supply, which could eventually act as a brake on stock markets. The main risk is a tightening of monetary conditions in the US. In our view, US interest rates might soon need to rise to contain a government and corporate borrowing spree that would otherwise fuel inflation. Total borrowing in the US is currently running at 16% of GDP, some 4 percentage points above the longer-term average.
