Fundamental Analysis Guide
The full 5-step framework — earnings quality is step 2
THE FIELD GUIDE · EARNINGS TRACK
Judge the quarter, not the headline.
Headline EPS beats are the least useful signal in an earnings print. These guides teach you to read cash conversion, working capital, margin mix, and guidance quality — the variables that actually change your estimates.
The insight most investors miss
Earnings quality is a signal, not a score.
Accrual buildup and DSO drift warn you the earnings number is deteriorating — before the stock reacts.
Timing
Read the earnings calendar like a roadmap
Pre/Post-Market
Earnings released after hours gives the market the overnight to digest the print; pre-market releases front-load the reaction into a gap open.
Whisper vs. Consensus
The published analyst estimate is the floor; the whisper number is the real bar the stock is graded against.
3-Day Drift
The initial reaction is noise; the more telling move is the 72-hour drift as institutions digest guidance and revise estimates.
Consecutive beats create complacency
Management guides conservatively to build a beat streak — the sandbagging dynamic. Analysts know this and factor it in, so by the time the number prints, the “beat” is often already priced in. A company that beats consensus every single quarter has trained the market to expect it, which quietly strips the surprise out of the surprise.
The problem compounds through analyst drift. After three or more consecutive beats, consensus creeps upward each quarter as analysts nudge their models toward management's revealed track record. The bar keeps rising until it becomes nearly impossible to clear — and that is exactly when a “guidance cut surprise” lands hardest, because estimates had drifted well past what the business can actually deliver.
Then there is the streak-break amplifier. A company coming off a six-quarter beat streak that misses by a mere $0.02 often falls further than a company with an irregular track record posting the same miss. Expectations had drifted to perfection, so any crack in the story forces a violent repricing as the market rebuilds its estimate of what “normal” looks like.
Spot the warning signs early →Earnings quality drives multiple expansion
Raised guidance signals confidence in unit economics. When management raises full-year EPS guidance mid-year, they are telling you they see the demand, the cost structure, and the conversion rate clearly enough to commit to a higher number in public. That visibility is scarce, and the market rewards it with multiple expansion — a higher P/E on earnings it now trusts more.
The gap between guidance and actuals is itself a credibility signal. Companies that consistently beat their own guidance by wide margins — more than 10% every quarter — are probably sandbagging, and persistent large beats raise an uncomfortable question: why does management keep lowballing? Companies that meet guidance within 2–5% are signaling a well-managed forecasting process, which is worth more to a long-term holder than a flashy beat built on a soft target.
Withdrawn guidance is the sharpest red flag of all. When management pulls full-year guidance mid-year, it means they genuinely cannot see 90 days ahead — and that opacity creates multiple compression before the bad quarter even arrives. The market does not wait for the actual miss; it re-rates the moment the visibility disappears.

Common questions
Earnings analysis — answered.
What is earnings quality analysis?
Earnings quality analysis evaluates whether reported profits reflect real cash generation or accounting choices. The key dimensions are cash conversion, GAAP-to-adjusted spreads, working capital trends, and the recurrence of one-time charges.
How do you spot an engineered EPS beat?
Look for beats driven by below-the-line items: lower tax rates, share buybacks shrinking the denominator, or one-time gains. A real beat shows up in revenue, gross margin, and operating cash flow. If those three miss while EPS beats, the beat usually isn't repeatable.
What is cash conversion ratio?
Operating cash flow divided by net income. A ratio consistently below 1.0 suggests earnings are running ahead of actual cash generation — a pattern that tends to resolve through earnings revisions or external capital raises.
What working capital signals matter most?
Rising days sales outstanding can indicate slow payment or early revenue recognition. Inventory building ahead of revenue growth can flag demand problems. Payables stretching longer can mask cash flow pressure. These show up in the cash flow statement before the income statement.
Can I score earnings quality without a terminal?

What's the difference between GAAP and adjusted earnings?
GAAP includes stock-based compensation, restructuring charges, and amortization of acquired intangibles. Adjusted excludes many of these. The gap is not inherently bad, but a large or growing spread — especially with charges that repeat quarter after quarter — warrants close scrutiny.
