Use Cases

Mode A — Market Earnings Calendar

"What major companies are reporting earnings this week?"

(Optional query params: from=YYYY-MM-DD&to=YYYY-MM-DD) Extract: company name, ticker, report date, timing (before market / after market), EPS estimate

Filter and group by day. Sort by market cap or analyst attention.

Mode B — Per-Stock Earnings Analysis

Earnings History & Next Quarter Estimate:

GET https://finskills.net/v1/stocks/earnings/{SYMBOL}

Extract:

• Last 4–8 quarters: date, epsActual, epsEstimate, epsSurprise, epsSurprisePercent
• Last 4–8 quarters: revenueActual, revenueEstimate, revenueSurprise
• Next quarter: epsEstimate, revenueEstimate
• Next report date, timing (AMC/BMO)

Analyst Estimates (revision trend):

GET https://finskills.net/v1/free/stocks/estimates/{SYMBOL}

Extract: current quarter EPS estimate, next quarter, current year, next year consensus Note upward vs. downward revision trend (compare to 30-day-ago estimates if available)

Latest News (pre-earnings catalyst check):

GET https://finskills.net/v1/news/by-symbol/{SYMBOL}

Extract: recent headlines, sentiment signals, any pre-announcements or guidance updates

Options Chain (for implied move):

GET https://finskills.net/v1/stocks/options/{SYMBOL}

Extract near-term ATM straddle price to calculate implied earnings move.

Analysis Workflow

Step 1 — Earnings Calendar View (Mode A)

Group events by day (Mon–Fri this week):

• Show pre-market (BMO) and after-close (AMC) separately
• Flag mega-caps (market cap > $100B) with ★
• Include consensus EPS estimate for context
• Highlight sector clusters (earnings tend to move entire sectors)

Step 2 — Earnings History Analysis (Mode B)

Build a beat/miss scorecard:

Compute:

• EPS Beat Rate: % of quarters beating EPS estimate
• Avg EPS Surprise: Mean % beat magnitude (positive = bullish quality)
• Revenue Beat Rate: % of quarters beating revenue estimate
• Consistency Score: 5/5 beats vs 3/5 vs 2/5 — flag inconsistency
• Trend: Is beat magnitude growing or shrinking? (quality signal)

Step 3 — Estimate Revision Momentum

Classify revision trend:

• Positive momentum: Estimates revised UP in last 30–90 days → analyst conviction rising
• Negative momentum: Estimates revised DOWN → potential guidance cut risk
• Stable: No significant revisions

This is a leading indicator — stocks with positive estimate revisions tend to outperform.

Step 4 — Implied Earnings Move (if options data available)

Calculate using ATM straddle at nearest expiration AFTER earnings date:

ATM Straddle Price = ATM Call Mid + ATM Put Mid
Implied Move %     = Straddle Price / Current Stock Price × 100
Expected Range     = [Current Price × (1 − implied_move%), Current Price × (1 + implied_move%)]

Compare to historical earnings moves (from earnings history — abs value of price change on earnings day):

• If implied move > average historical move: options are pricing in extra uncertainty → consider neutral strategies
• If implied move < average historical move: options may be cheap for directional play

Step 5 — Pre-Earnings Assessment

Summarize the opportunity:

Bull Case (if expecting beat):

• Revenue acceleration + margin expansion signals?
• Positive estimate revisions?
• Strong sector tailwinds?

Bear Case (if expecting miss or disappointment):

• Slowing beat magnitude trend?
• Recent negative estimate revisions?
• Macro headwinds for the sector?

Key Watch Items:

• Management guidance language (forward-looking statements)
• Segment breakdowns to watch (e.g., Cloud for MSFT, iPhone for AAPL)
• Margin trajectory (gross margin, operating margin vs estimates)

Limitations

• Earnings dates can shift by 1–2 weeks; always verify directly with the company's IR page.
• Implied move is based on options chain snapshot; liquidity affects pricing accuracy.
• EPS surprise history may not account for non-GAAP vs. GAAP differences.
