Investment firm Ruffer has warned that market narratives, particularly around artificial
intelligence, are increasingly influencing share prices and could increase the risk
of sharp market reversals.

In its Ruffer Review 2026, investment specialist Gemma Cairns-Smith argues that 
social media, retail trading platforms and investment strategies linked to market
trends are helping popular investment themes spread more quickly and influence prices.

The AI boom is a key example. Strong investor demand has driven high valuations 
among a small group of large US technology companies, raising questions about whether
expected returns will justify their substantial spending. Ruffer also points to 
the growth of speculative financing as a potential warning sign.

Retail investors are playing a greater role in market movements, supported by low-
cost trading and social media discussions. Institutional investors can also follow
prevailing market trends because their performance is often measured against benchmarks,
making it difficult to move away from popular investments.

Passive funds and systematic trading strategies can reinforce these movements. When
markets rise and volatility remains low, some strategies increase exposure. When
sentiment changes and volatility increases, the same systems can trigger selling,
potentially accelerating market declines.

Ruffer identifies three stages in a market narrative: an early phase when an asset
may be undervalued, a period when the investment story attracts wider interest, 
and a final stage when prices fall as sentiment changes.

Gold mining shares provide an example of the early stage. During 2023 and 2024, 
gold prices rose while mining shares lagged. Ruffer increased exposure as it saw
potential for mining companies to benefit from higher gold prices and improving 
margins. During 2025, mining shares outperformed as investor interest increased.

By contrast, Ruffer believes AI-related valuations are showing warning signs, although
it does not claim the market has reached its peak. The firm argues that investors
should assess company fundamentals and valuations rather than relying solely on 
the popularity of an investment theme.

Ruffer says it does not attempt to predict the exact peak of a market cycle. Instead,
it focuses on prices, underlying fundamentals and the potential for different outcomes,
with an emphasis on balancing exposure to growth opportunities against assets intended
to protect capital.
