Earnings Call Summary & Analysis
Framework
IRON LAW: Separate Facts from Spin
Management presentations emphasize positives and downplay negatives.
Your job is to extract: (1) hard numbers, (2) forward guidance with
specificity level, and (3) what management DIDN'T say (notable omissions).
"Strong momentum" without numbers is spin.
"Revenue grew 15% to NT$2.3B" is a fact.Earnings Call Structure

Analysis Steps
Phase 1: Extract Numbers
- Revenue, EPS, margins — actual vs consensus vs prior guidance
- Beat or miss on each line item
Phase 2: Evaluate Guidance
- Did they raise, maintain, or lower guidance?
- How specific is the guidance? (range vs vague)
- Implied assumptions (growth rate, margin trajectory)
Phase 3: Read the Q&A
- What are analysts asking? (reveals market concerns)
- Where does management deflect or give vague answers? (red flags)
- New information that wasn't in prepared remarks
Phase 4: Compare to Market Reaction
- Stock price move post-earnings
- Does the market reaction align with the numbers? (sometimes a beat is sold off = guidance disappointed)

- Beats can be "low quality": Beating EPS by cutting costs while revenue misses is a low-quality beat. Revenue beats with margin expansion is high quality. Differentiate.
- Guidance matters more than actuals: The market prices in expectations. A company that beats Q3 but lowers Q4 guidance will often sell off. Focus on forward-looking signals.
- Taiwan 法說會 specifics: Many Taiwan companies (especially TSMC, MediaTek) hold English-language calls. Others are Chinese-only. MOPS has summary notes even if you can't attend live.
- Consensus estimates can be stale: If estimates haven't been updated recently, a "beat" may just mean the bar was set too low. Check when consensus was last revised.
- One quarter doesn't make a trend: Don't overreact to a single quarter. Look at 3-4 quarters to identify real trends vs noise.
