When Missing Becomes Structure: Intent-Preserving Policy Completion from Financial KOL Discourse

Summary

A new intent-preserving policy completion framework addresses the challenge of converting financial Key Opinion Leader (KOL) social media discourse into executable trading strategies without making assumptions about unspecified execution decisions. The framework observes that KOL statements typically provide directional intent (what to buy or sell and why) but systematically omit execution details (when, how much, how long). By treating KOL discourse as a partial trading policy, the system uses offline reinforcement learning to complete these missing execution decisions while preserving the original intent. Experiments conducted on multimodal KOL discourse from YouTube and X, spanning 2022-2025, demonstrate that this framework, named KICL, achieves superior returns and Sharpe ratios on both platforms. Furthermore, KICL maintains zero unsupported entries and zero directional reversals, with ablations confirming an 18.9% return improvement over a KOL-aligned baseline.

Key takeaway

For research scientists developing automated trading systems from social media, KICL offers a robust method to translate qualitative KOL intent into quantitative execution policies. You should consider integrating intent-preserving policy completion to enhance strategy performance and mitigate risks associated with unsupported entries or directional reversals, potentially yielding significant return improvements.

Key insights

KOL discourse provides directional intent, not execution, which can be completed via offline reinforcement learning.

Principles

• KOL gaps are structured, not random.
• Preserve intent while completing policies.

Method

The KICL framework treats KOL discourse as a partial trading policy, using offline reinforcement learning to complete missing execution decisions (when, how much, how long) around the expressed directional intent.

In practice

• Convert KOL advice into executable strategies.
• Improve returns from social media insights.

Topics

• Financial KOL Discourse
• Offline Reinforcement Learning
• Intent-Preserving Policy
• Algorithmic Trading
• Investment Strategy Automation
