A One-Day China A-Share Strategy Using Weibo Sector Sentiment

Summary

The document outlines a daily sentiment-based strategy for China A-share stocks using posts from recognized financial accounts on Weibo. It proposes collecting posts during the pre-market period, considering four actively discussed sectors, and identifying a sector favored by at least three expert accounts. Leading stocks in a qualifying sector are equally weighted. The strategy buys at the open, holds for one trading day, and sells at the next day’s open.

The headings indicate that the broader project covers account selection, sector definitions, Chinese-language parsing, sentiment analysis, and strategy performance, and that accompanying materials include a report and code files. However, those methods, the stock-selection details, performance figures, and evaluation design are not present in the supplied text. It therefore communicates a testable strategy outline but provides no evidence here about returns, transaction costs, slippage, or robustness. The rule depends on the quality and timing of social-media data and would need realistic execution assumptions and out-of-sample testing before its results could be assessed.

Key ideas

• The proposed signal uses pre-market posts from selected Weibo financial accounts.
• A sector qualifies when at least three accounts favor it.
• Leading stocks in a qualifying sector are equally weighted and bought at the open.
• Positions are held for one day and sold at the following session’s open.
• The supplied text gives no performance results or detail on execution costs and robustness.
