From Memes to Themes: Addressing Emergent Risk
The meme stock craze was a reminder that risk isn’t a static concept. It evolves with global events, technology, and policy changes. Traditional risk metrics are useful, but they often fail to capture thematic risks.

Key takeaways
- Natural language processing (NLP) can help identify thematic risks early so portfolio managers can adjust exposures, hedge positions, and build resilience against these risks.
- We use NLP to transform vast amounts of text—such as earnings call transcripts, regulatory filings, and press releases—into insights that help manage risk and find opportunity.
- In two examples, NLP informed our investment decisions on MetLife and EMCOR Group, providing a deeper understanding that enabled proactive portfolio adjustments.
Executive summary
Addressing emergent risk
The meme stock craze highlighted a crucial lesson for investors: risk is not a static concept. It evolves with global events, technology, and policy. While traditional metrics like volatility remain useful, they often fail to capture thematic risks that emerge suddenly and affect specific sectors or companies.
Identifying and mitigating these dynamic risks calls for a proactive approach that blends quantitative analysis with qualitative insights. By identifying vulnerabilities early, portfolio managers can adjust exposures, hedge positions, and build resilience against thematic risks. We see natural language processing (NLP) as an especially powerful tool for this.
Using language to uncover hidden risks
NLP is a branch of artificial intelligence (AI) that allows machines to understand and analyze human language. For investors, this technology transforms vast amounts of unstructured text—such as earnings call transcripts, regulatory filings, and press releases—into actionable insights. It helps connect companies to emerging themes and risks, even before they become widespread knowledge.
By using NLP to analyze company communications, we can detect subtle shifts in language that signal new opportunities or threats such as tracking management sentiment on AI adoption, identifying mentions of supply chain vulnerabilities, or recognizing the long-term impact of remote work on commercial real estate. This data-driven approach offers a more granular view of a company's fundamental drivers, allowing for more informed decisions.
NLP in action
Effective risk management isn't just about avoiding threats; it's also about seizing opportunities. Two examples of how NLP informs our investment decisions include MetLife and EMCOR Group.
Our NLP research showed that MetLife, a global insurer, had significant exposure to commercial real estate, a sector facing a structural decline due to the rise of remote work. This exposure created a thematic risk that wasn't immediately obvious from traditional analysis. In response, we trimmed the position to manage this risk.
Conversely, our analysis of EMCOR Group, a specialty contractor, revealed its growing role in building the infrastructure for AI-powered data centers. With this insight, we increased our position, gaining valuable exposure to the AI infrastructure theme and adding balance to our portfolios. In both cases, NLP provided a deeper understanding that enabled proactive adjustments.
In an era of rapid change, integrating advanced tools like NLP into the investment process is essential. By monitoring thematic risks at the stock level, portfolio managers can better anticipate disruptions, manage unintended exposures, and position portfolios for long-term resilience and growth.
