How earnings reports move stocks

Q: Why might a stock fall on an earnings beat?

Expectations were above consensus; guidance disappointed; stock was overbought going in.

Q: What's a 'beat-and-raise'?

Beat the current quarter AND raise guidance — strongest bullish earnings signal.

Beats, misses, guidance, and why prices can fall on a 'good' report.

TL;DR

Earnings reports — released quarterly — are the single biggest scheduled catalyst for individual stocks. Markets care about the print AND the guidance. A 'good' earnings report can still tank a stock if guidance disappoints.

Inside an earnings report

Four numbers and one document drive most of the reaction.

→Revenue (top line) — sales for the quarter
→EPS (bottom line) — earnings per share
→Guidance — management's forecast for next quarter/year
→Margins — gross, operating, net
→The earnings call transcript fills in the rest

Beat / miss / in-line

Markets trade the deviation from consensus, not the absolute number.

→Beat — actual > consensus. Bullish, unless priced in.
→Miss — actual < consensus. Bearish, sometimes brutally.
→In-line — actual ≈ consensus. Guidance can still move it.
→Beat AND raise — both EPS and guidance above. Strongest bull signal.
→Miss AND lower — opposite. Multi-day sell-off.

Why a good report can sell off

Common scenarios: the stock was up 30% into earnings — expectations were already higher than consensus. Beat-and-lower-guide signals slowing momentum. Currency or segment surprise hidden in the details.

Worked example

Beat-and-lower on a hot stock

META rallied 25% into Q3 earnings. Beats on EPS and revenue. Q4 guidance midpoint slightly below consensus.

Takeaway

When expectations are stretched, anything less than a clear beat-and-raise gets sold. The bar matters more than the number.

Common mistakes

What to avoid

!Trading the print in the first minute — spreads are brutal
!Ignoring guidance — analysts adjust models off it
!Believing 'beat = up' — context (what was priced in) is everything
!Buying calls into earnings — implied vol is highest there
