Earnings Components

EPS (Earnings Per Share)

EPS = (Net Income - Preferred Dividends) / Weighted Average Shares

Beat/Miss = Reported EPS - Consensus EPS

where: Net Income GAAP net profit for the period · Preferred Dividends dividends owed to preferred holders · Weighted Average Shares time-weighted diluted share count · Consensus EPS sell-side analyst median estimate does: the basic per-share profit metric and the surprise variable that drives most short-term post-print moves — used to quantify the earnings surprise that feeds Post-Earnings Announcement Drift signals.

Revenue

Revenue Beat/Miss = Reported Revenue - Consensus Revenue
Revenue Growth = (Revenue_t - Revenue_{t-4}) / Revenue_{t-4}

where: Reported Revenue GAAP top-line for the period · Consensus Revenue sell-side median estimate · Revenue_t revenue this quarter · Revenue_{t-4} revenue same quarter prior year does: the top-line surprise and year-over-year growth rate — used to separate EPS beats driven by real demand from beats driven by buybacks or margin tricks, and to track demand-trajectory inflections.

Guidance

Forward guidance often matters more than current quarter results:

Guidance Type Market Reaction
Raised Typically positive
Maintained Neutral to slightly positive

Earnings Trading Strategies

Strategy 1: Pre-Earnings Run-Up

Entry: 5-10 days before earnings
Exit: Day before earnings or at open
Rationale: Stocks tend to drift up before earnings
Risk: Run-up doesn't always happen

Strategy 2: Straddle/Strangle

Buy ATM straddle before earnings
Profit if actual move > implied move
Risk: IV crush after earnings

Strategy 3: Post-Earnings Drift

Entry: Day after earnings if significant surprise
Direction: Follow surprise direction
Hold: 20-60 days
Exit: When drift exhausts or time-based

Strategy 4: IV Crush Play

Sell options before earnings (high IV)
Buy back after earnings (IV drops)
Profit from volatility contraction
Risk: Large directional move

Practical Guidelines

  1. Know the Implied Move — Options market tells you expected move
  2. Compare to History — Is implied move above/below average?
  3. Watch IV Rank — High IV = expensive options = favor selling
  4. Position Size — Earnings are binary events; reduce size
  5. Have a Plan — Decide entry/exit before the event
  6. Don't Gamble — Earnings trading is speculation, not investing
  7. Track Your Record — Keep stats on your earnings trades
