Why this matters for beginners
Beginners often think 'good earnings = stock up'. In reality, prices already embed a forecast. The reaction depends on how reality compares to that forecast.
Main explanation
Before earnings, analysts publish consensus estimates for revenue, EPS, and guidance. The stock price already reflects something close to those numbers.
What moves the stock is the surprise, beating or missing those expectations, and especially what management says about the future (guidance).
A great quarter that comes with cautious guidance can send the stock down. A weak quarter with strong guidance can send it up.
Over the long run, earnings results dominate. Over short windows, expectations and narrative dominate. Confusing the two is a common beginner trap.
Example using a real company
A high-flying tech name 'beats' on revenue and earnings but trims next-quarter guidance by 2%. The stock drops 10% because the market had priced in stronger forward growth.
- →Consensus EPS $2.00. Reported $2.10, looks like a beat. Guidance lowered. Stock falls.
- →Consensus EPS $2.00. Reported $1.95, looks like a miss. Guidance raised meaningfully. Stock rises.
Common beginner mistakes
- ✕Buying right before earnings hoping for a 'pop'.
- ✕Assuming a beat always means the stock will go up.
- ✕Ignoring forward guidance and focusing only on the headline number.
