What it does
This skill teaches the agent a finance-analyst framework for reading company earnings. Once installed, when asked about a stock's earnings, the agent can judge whether analyst estimates are being revised up or down, how big a result was versus expectations, and whether management's guidance language is positive or negative. It also explains post-earnings price drift (PEAD), the tendency of stock prices to keep moving in the direction of an earnings surprise for 60-90 days, and lists earnings-quality red flags such as cash flow lagging reported profit. The file is a reference guide with formulas and rules of thumb; it does not contain live market data or a finished trading system.
Great for
- Equity analysts or students who want a structured checklist for earnings season
- Investors researching US or Hong Kong listed companies before an earnings report
- Quant researchers looking for documented earnings-based factor definitions to build on
Skip it if
- People expecting real-time or verified financial data: the skill has no data source and the agent must still obtain figures elsewhere, so it may invent numbers if none are supplied
- Making actual trading decisions without independent review: the return ranges quoted are generic, not validated for any specific stock or period, and acting on them can cause financial loss
- Non-US/HK markets: the skill is scoped to US/HK equities and its thresholds are not calibrated for other exchanges
Try asking
- “Here is a company's last four quarters of EPS actuals and consensus. Compute the SUE for each and tell me whether the surprises look like PEAD candidates.”
- “Analyze this earnings release for guidance language. Is the company raising, reaffirming, or quietly cutting its full-year outlook?”
- “Using the pre-earnings checklist, prepare a consensus snapshot and list the key items to watch for this quarter's report on this US stock.”
- “Check this earnings report for red flags such as cash flow falling behind revenue growth or a large gap between GAAP and non-GAAP EPS.”

Ask for the task
No special command needed — the agent reads the skill's description and loads it when your request matches. Try one of the prompts above.
Get better results
- Supply the actual consensus, actuals, and guidance figures yourself, with sources, so the agent does not have to estimate them.
- Treat the percentage return ranges and thresholds as starting points to test against your own data, not as established facts for a given stock.
- Ask for the reasoning behind any signal, so you can check the guidance-language interpretations against the actual filing text.
