Earnings RecapSAFE
A collection of skills for AI financial analysis.
Overview
From the repository's own README, as read at the audited commit. Badges and raw HTML are left out.
Generate a post-earnings analysis for any stock using Yahoo Finance data.
What it does
- Shows the EPS beat/miss result with surprise percentage
- Presents quarterly financial trends (revenue, margins, EPS) over the last 4 quarters
- Calculates the stock price reaction on earnings day
- Compares the reaction to the stock's average earnings-day move
- Provides context on margin trends and revenue growth trajectory
Triggers
AAPL earnings recap, how did TSLA earnings go, MSFT earnings results, did NVDA beat earnings, post-earnings analysis, earnings surprise, what happened with GOOGL earnings, earnings reaction, stock moved after earnings, earnings report summary, EPS beat or miss, quarterly results, AMZN reported last night
Prerequisites
- Python 3.8+

name: earnings-recap
description: >
Analyze a company's most recent (or a specified past) earnings report from Yahoo
Finance data (yfinance): actual vs estimated EPS, surprise size, revenue and margin
trends, and the stock's price reaction. Use this skill whenever the user asks how
earnings went — beat or miss, earnings surprise, quarterly results, the
post-earnings move, or an earnings call recap — including casual references to a
past report such as "AMZN reported last night" or "how did they do". For an
upcoming report, use earnings-preview.

# Earnings Recap Skill
Generates a post-earnings analysis using Yahoo Finance data via [yfinance](https://github.com/ranaroussi/yfinance). Covers the actual vs estimated numbers, surprise magnitude, stock price reaction, and financial context — a complete picture of what happened.
**Important**: Data is for research and educational purposes only. Not financial advice. yfinance is not affiliated with Yahoo, Inc.
---
## Step 1: Ensure yfinance Is Available
**Current environment status:**
```
!`python3 -c "exec('try:\n import yfinance\n print(\'yfinance \' + yfinance.__version__ + \' installed\')\nexcept Exception:\n print(\'YFINANCE_NOT_INSTALLED\')')"`
```
If `YFINANCE_NOT_INSTALLED`, install it:
```python
import subprocess, sys
subprocess.check_call([sys.executable, "-m", "pip", "install", "-q", "yfinance"])
```
If already installed, skip to the next step.
---
## Step 2: Identify the Ticker and Gather Data
Extract the ticker from the user's request. Fetch all relevant post-earnings data in one script.
```python
import yfinance as yf
import pandas as pd
ticker = yf.Ticker("AAPL") # replace with actual ticker
# --- Earnings results ---
earnings_dates = ticker.get_earnings_dates(limit=12) # report timestamps, newest first
earnings_hist = ticker.earnings_history # last 4 quarters, indexed by fiscal quarter-end, oldest first
# --- Financial statements (about five quarters, newest first) ---
quarterly_income = ticker.quarterly_income_stmt
quarterly_cashflow = ticker.quarterly_cashflow
quarterly_balance = ticker.quarterly_balance_sheet
# --- Context ---
info = ticker.info
news = ticker.news
recommendations = ticker.recommendations
```
### What to extract
| Data Source | Key Fields | Purpose |
|---|---|---|
| `get_earnings_dates()` | Earnings Date, EPS Estimate, Reported EPS, Surprise(%) | Which report, when, and the beat/miss |
| `earnings_history` | epsEstimate, epsActual, epsDifference, surprisePercent | Last four quarters' results by fiscal quarter |
| `quarterly_income_stmt` | TotalRevenue, GrossProfit, OperatingIncome, NetIncome, BasicEPS | Actual financials |
| `history()` | Daily closes around each report | Stock price reaction |
| `info` | currentPrice, marketCap, forwardPE | Current context |
| `news` | Recent headlines | Earnings-related news |
---
## Step 3: Find the Report and Measure the Reaction
`earnings_history` is indexed by fiscal quarter-end, not by announcement date, so take report timing from `get_earnings_dates()`: the most recent report is the newest row with a `Reported EPS`. Its timestamp (US Eastern) sets the reaction window: at or after 16:00 means the company reported after the close; anything earlier means before the open or, occasionally, during the session. If the user asked about a specific quarter, use that row instead.
```python
def earnings_reaction(ticker, report_ts):
"""% move from the last close before the report to the first close after it."""
daily = ticker.history(start=(report_ts - pd.Timedelta(days=10)).date(),
end=(report_ts + pd.Timedelta(days=10)).date())
closes = daily["Close"]
days = closes.index.date
d = report_ts.date()
if report_ts.hour >= 16: # reported after the close: report-day close -> next close
pre, post = closes[days <= d], closes[days > d]
else: # before the open or intraday: prior close -> report-day close
pre, post = closes[days < d], closes[days >= d]
if pre.empty or post.empty:
return None # the reaction session hasn't closed yet
return (post.iloc[0] / pre.iloc[-1] - 1) * 100
reported = earnings_dates[earnings_dates["Reported EPS"].notna()]
latest_ts = reported.index[0]
reaction_pct = earnings_reaction(ticker, latest_ts)
# Typical earnings-day move over the prior four reports
prior_moves = [earnings_reaction(ticker, ts) for ts in reported.index[1:5]]
avg_abs_move = pd.Series([abs(m) for m in prior_moves if m is not None]).mean()
```
If `reaction_pct` is `None`, the report came after the most recent close; say the regular-session reaction is still pending (an intraday `history(..., prepost=True)` call shows the after-hours move if the user wants it).

## Step 4: Build the Earnings Recap
Cover these areas, leading with the result:
1. **Headline result** — EPS actual vs estimate with the surprise %, revenue with year-over-year growth, and the stock's reaction.
2. **Estimates vs actuals** — EPS estimate, actual, and surprise ($ and %) for the quarter in question.
3. **Quarterly trends** — revenue, gross margin, operating margin, and EPS for the recent quarters, with margins computed from the statements (gross profit / revenue, operating income / revenue). yfinance usually returns about five quarters, so year-over-year growth is available for the latest quarter only (column 0 vs column 4); show sequential change for the others rather than inventing a comparison.
4. **Price reaction** — the move in the reaction session, how it compares with the stock's average absolute earnings move over the prior four reports, and whether the stock has since held, given back, or extended the move.
5. **What changed** — margin direction vs the prior quarter, any shift in the revenue growth trajectory, how this surprise compares with the company's usual pattern, and current analyst sentiment if available.

Questions
What does the Earnings Recap skill do?
A collection of skills for AI financial analysis.
Is Earnings Recap safe to install?
The audit found nothing in the source that contradicts what it says it does, and graded it B (89/100). Grade A is held back for packages that have also passed a sandboxed behavioural run, which is why a clean skill reads B.
What can Earnings Recap access on my machine?
The audit observed no filesystem, network or shell use at all in its source.
Which assistants does Earnings Recap work with?
Its documentation mentions claude-code. That is what the text claims, not a compatibility test we ran.
How current is this page?
The grade is for one exact copy of the source (317cbce031f1), read on 2026-10-08. The repository is watched, and a new audit runs when it changes — this is the first audit.
