## Bond Yields Surge
Bond yields have become the most important macroeconomic theme after the 2022 surge, with new highs seen across developed markets.
## Global Equity Alpha Breadth Weakens
Rising yields make low-growth stocks look bad as bonds pay more attractive yields, reducing market breadth.
## Whisky Portfolio Outperforms
Whisky boosted returns to 13.6% in 2026, outperforming the FTSE 100 by 3.7%.
## Soda Portfolio Lags
Soda lagged this year, 3.9% behind the balanced index, due to conservative asset allocation.
## Shiller P/E Ratio at 41x
The Shiller P/E Ratio shows current stock valuations at 41x, higher than 1999's 45x and 1929's 31x.
## Bond Risk Analysis
Gilt index shows modified duration of 7%, meaning a 1% yield move could impact capital by 13%.
## Market Breadth Deterioration
Market breadth has deteriorated as fewer stocks beat the market and more lag behind.
## High Beta Stocks Underperform
High beta stocks have underperformed, with volatility increasing as the market concentrates.
## Commodities Mixed Performance
Oil and copper performed well, while gold and silver cooled after January due to market shifts.
## AI Trade Weakens
The AI trade has weakened again after initial July pullback, signaling potential market rotation.
## Multi-Asset Investor Strategy
The Multi-Asset Investor uses Whisky and Soda portfolios for capital preservation and growth opportunities.
## Market Outlook
Markets face extreme conditions with energy and bond shocks, suggesting change is coming for investors.
## Sovereign Debt Crisis Risk
Rising yields may morph into a sovereign debt crisis as governments struggle with interest bills.
## Next Steps for Investors
Investors should focus on oversold sectors like property, consumer, emerging markets, and small-caps for opportunities.
## Key takeaway

Rising bond yields and shrinking market breadth signal potential sovereign debt crisis and opportunity in value stocks.
