Four questions, asked in order
Most research tools give you one number and let you guess what it means. Aperto asks four questions, in a fixed sequence, because the order changes what a "yes" is worth.
Pull up any stock on a typical screener and you get a wall of numbers at once: P/E, RSI, analyst targets, a moat rating buried somewhere in a report you'll never read. Nothing tells you which number to check first, or what happens if two of them disagree. You end up anchoring on whichever one confirms what you already wanted to believe.
Aperto asks four questions instead, and asks them in order, because each one only means something once the one before it has answered:
Why invest in this business?
Before price, before timing, before anything else: is this a good business? We score quality from five structural pillars — the kind of thing you'd check if you were buying the whole company, not a ticker. The output isn't a single number pretending to be objective. It's a moat rating (narrow, wide, none) built across bear, base, and bull scenarios, so you can see how much of the quality case depends on things going right.
A wide-moat business at a terrible price is still a bad trade. But a narrow-moat business at a great price is usually a value trap, not a bargain. WHY exists to catch that second case before you fall for it.
What is it actually worth?
Only once WHY clears do we ask WHAT. Aperto runs several independent valuation lenses on a business, each with its own assumptions, and blends them into a range rather than a point estimate. We publish that range even when it's wide, because a narrow range built on shaky assumptions is a worse answer than an honest wide one. Sometimes the lenses disagree so much that publishing any single number would be false precision, and the engine says so directly instead of picking a favorite. We wrote about why that refusal is a feature, not a bug, in a separate post.
When is the right time to buy?
A great business at a fair price can still be a bad trade this week. WHEN checks technical confluence across eleven indicators, purely for entry discipline. It carries no opinion on the business and no opinion on value; those questions are already answered by the time WHEN runs. It only asks whether the tape agrees this is a reasonable moment to act, or whether you're early.
How will you know if you're wrong?
The three questions above get you into a position. HOW is what happens after. Every thesis you lock gets checked against eight stress tests, run fresh against each new filing: the specific facts that would mean your original reasoning broke, stated in advance, before you have a live position defending it in your head. Most people write their exit rules after the trade is already down 20%, when the person writing them is no longer the same person who made the original case.
Why the order is the point
Run these four questions in a different order and they answer different things. Start with WHAT and you'll rationalize a mediocre business because the multiple looks cheap. Start with WHEN and you'll chase a chart with nothing under it. Aperto fixes the sequence so a cheap price can't excuse a bad business, and a good business can't excuse an irresponsible price.
None of the four layers is a verdict on its own. Together, in order, they're a discipline: articulate the case for a wide moat, put a number range on it, wait for a defensible entry, and write down what would prove you wrong before you're emotionally attached to being right.
