Part 8 · In practice: your own routine for reading the economy · Lesson 43
Graduation: your own weekly economic checklist
Turn what you learned in 43 lessons into a 10-minute habit once a week. Check the seven items in order, leave a one-line note, and you graduate.
QToday's question
You've learned all 43 lessons, but on Monday morning you don't know what to look at first. How do you turn what you learned into a habit you use every week?
After splitting stock prices into the two knobs of earnings and multiple in Lesson 1, you moved through 43 lessons covering inflation, interest rates, jobs, exchange rates, commodities and sentiment. Knowledge builds up, but it fades quickly if you don't use it every week. In this final lesson, we compress everything you've learned into seven checks and set an order that takes 10 minutes or less.
MAPLearning map for this lesson
We build it up in three steps. At the end of each step, a 'Quick check' lets you test your understanding before moving on.
This lesson wraps up the whole course. Recall one representative lesson from each part: Lesson 1 stock price = earnings × multiple, Lesson 8 how to read CPI, Lesson 13 central banks, Lesson 19 the jobs report, Lesson 23 what the exchange rate means, Lesson 29 oil prices, Lesson 36 reading the sector map, and Lesson 40 interpreting headlines. For any lesson you remember vaguely, you can reopen it right away from the 'Lesson 43 map' below.
- STEP 1 · Basic conceptsAll 43 lessons on one page
You can explain with a one-page map how the eight parts connect, and state the two basic questions to ask of every piece of news.
- STEP 2 · Understanding the mechanicsThe seven checks and their order
You can explain what the seven weekly checks are, and why you look from the big winds to the small winds.
- STEP 3 · Real-world applicationThe Monday morning 10-minute routine
You can fill in the checklist with a real week's data, and write a one-line note containing the conditions to check next week.
STEP 1All 43 lessons on one page
Before building the checklist, let's lay out the road you've walked so far as a one-page map.
Easy analogy · The pre-flight checklist
Pilots who have flown thousands of hours still check a checklist item by item before takeoff. Not because their memory is bad, but so they don't miss anything when they are busy or tense.
Investing is the same. On days when the market swings hard, an order you set in advance is worth more than the knowledge in your head. The goal of this lesson is to turn the knowledge from 43 lessons into a checklist you open once a week.
The eight parts are one story
The Economics course is split into eight parts, but it is really one story running in a single line. Part 1 set the starting point that a stock price is the , and Part 2 (inflation) and Part 3 (interest rates) taught the forces that shake the multiple knob the hardest. Part 4 (jobs and the economy) moves both the earnings knob and the central bank's judgment, and Part 5 (exchange rates and exports) is the link unique to the Korean market. Part 6 (commodities and the global economy) is the wind that blows in from outside, and in Part 7 we connected all of this to sectors and valuation. The final Part 8 is the process of applying that knowledge to real news, to crises, and to a weekly habit.
So the map flows from top to bottom: the basic structure of the economy (Part 1) → the value and price of money (Parts 2–3) → the temperature of the economy (Part 4) → links between Korea and the world (Parts 5–6) → translation into stocks (Part 7) → practice (Part 8).

Two questions to ask of every piece of news
Condensed to one sentence, the 43 lessons say this: "Does this news change companies' earnings, or the multiple the market assigns? And was it already expected by the market?" The first question is the two knobs of Lesson 1, and the second is the of Lesson 20 and the idea of Lesson 14.
Two questions to use every week
1 Is it the earnings knob or the multiple knob? The economy, exports and commodities mainly move earnings; interest rates, sentiment and liquidity mainly move the multiple. 2 How different was it from expectations? The market reacts to the gap from expectations rather than to the number itself.
These two questions are the backbone of the checklist. The seven items you are about to see are, in the end, a list for making sure you don't miss "what winds blew on the two knobs this week, and what winds are forecast for next week".
Quick checkThe headline "US 10-year yield surges, growth stocks weak" is mainly about which knob?
STEP 2The seven checks and their order
The order you look in matters as much as what you look at. Start with the big winds and work down to the small winds.
Why start with the big winds?
When checking the weather, you first see whether a typhoon is coming, then look at temperature and wind. Economic indicators work the same way. Only when you know the direction of interest rates and the exchange rate, the benchmarks for all asset prices, do you have a frame for interpreting the numbers below them. For example, if growth stocks were weak in a week when interest rates rose sharply, that is likely the result of the whole multiple knob being pressed down, not a problem with individual companies (Lesson 17). If you reverse the order, you end up attaching separate reasons to each sector's move and tend to miss the big flow.
So the checklist follows this order. Summarize the week by what has already happened (market results), then look in turn at the biggest wind (interest rates), the winds unique to the Korean market (the exchange rate and foreign investors) and the wind from outside (commodities), then check the winds yet to come (this week's calendar). Finally, take the market's temperature (sentiment), and close with how all these winds reach sectors (the sector map).
| Order | Item | Key question | Lessons covered |
|---|---|---|---|
| 1 | Last week's market results | Which way, and how much, did the KOSPI, S&P 500 and Nasdaq move? | Lessons 1, 32 |
| 2 | Interest rate | Are the US 10-year yield and the policy rate rising or falling? | Lessons 13, 14, 16 |
| 3 | Exchange rate and foreign investors | Is the won strengthening, and are foreign investors buying or selling? | Lessons 23, 24, 27 |
| 4 | Commodities | What are oil, gold and copper saying? | Lessons 29, 30, 31 |
| 5 | This week's schedule | What are the expected figures for CPI, jobs, FOMC, BOK Monetary Policy Board and trade statistics? | Lessons 8, 19, 20 |
| 6 | Investor sentiment | Are the VIX and margin loan balance showing fear or overheating? | Lesson 39 |
| 7 | Sector map | Are the winds a tailwind or a headwind for the sectors I follow? | Lessons 35, 36 |
See it in a picture: this week's checklist
When this page opens, the checklist below loads Robin Invest's latest market and macro data and attaches the current number to each item. Tick the items you've checked and they are saved in this browser as this week's record (Mon–Sun); when next week comes, a new checklist starts. You can leave a one-line note at the bottom and print it or save it as a PDF.
Loading the latest data…
Number sources: Robin Invest Today's Market (Naver Pay Securities, FRED), Macro Map (FRED, BOK ECOS), Short Selling & Margin Loans (KOFIA FreeSIS, KRX). If the data can't be loaded, data updated on 2026-10-04 is shown. Checks and notes are saved only in this browser and are not sent to a server.
Each item has a set 'what to write down'
For a checklist to become a habit, each item needs a short, fixed description of which number to look at and what to write. For market results, write only the direction and size; for interest rates, only the 10-year yield's level and its change over the past month; for the exchange rate, only the direction of USD/KRW and the sign of foreign investors' net buying. For commodities, look at the direction of oil first and check whether gold and copper are saying different things (gold often speaks of anxiety, copper of the economy). For the calendar, write the date together with the so you can judge the surprise right away on release day. For sentiment, write the level of the and the direction of change in the margin loan balance; for the sector map, write the of the sector you follow and the top reason behind that score.
Common misconceptions
- "The more indicators you watch, the more accurate you are?"
- No. As indicators multiply, conflicting signals multiply too, and judgment tends to blur. The reason we cut it down to seven is that it has to be an amount you can check without fail every week to become a habit.
- "Fill out the whole checklist and next week's stock price direction comes out?"
- The checklist is not a forecasting tool; it is a tool for not missing things. The result is not "up" or "down" but a note that says "if this condition appears, I check it this way".
- "It only means something if you look every day?"
- For long-term investors, weekly is actually better than daily. It cuts the day-to-day noise and lets you focus on whether the direction of the big winds, such as interest rates and the exchange rate, is changing.
Quick checkWhen writing 'this week's calendar' in the checklist, what must you write alongside the date?
STEP 3The Monday morning 10-minute routine
Now let's fill in the checklist with a real week. The numbers are Robin Invest data from the first week of October 2026, when this lesson was written.
Split the 10 minutes like this
| Time | What to do | Where to look |
|---|---|---|
| 1 min | Check last week's market results and the overnight US market | Home · Today's market |
| 3 min | Write down the numbers and directions for interest rates, the exchange rate, oil and sentiment | Macro Map · Current phase, Short Selling & Margin Loans |
| 1 min | Check the direction of foreign and institutional flows | Market Data · Investor Flows |
| 2 min | Write down this week's indicator and monetary policy calendar with expected figures | Calendar |
| 2 min | Check the environment score of the sectors you follow and the top reason | Environment score |
| 1 min | Write a one-line note and check the conditions in last week's note | The checklist above |
The last minute is the most important. The moment you check whether the conditions you wrote down last week actually appeared, and if so whether the market reacted as expected, the checklist becomes your own review notebook rather than a mere record. After just a few weeks, habits start to show, such as "I reacted sensitively to interest rates but often missed exchange rate signals".
Filling it in with an example: the first week of October 2026
The three examples below fill in the checklist with the actual numbers from the Robin Invest Macro Map and market data (updated 2026-10-04), as of the October 2, 2026 close. These numbers are that week's record; you can see the current numbers in the checklist above.
Example 1 · Start with interest rates: a week when the multiple knob was pressed down
The US 10-year was 5.28%, in the top 2% of the past five years, and had risen 0.79 percentage points over three months. The upper bound of the Fed's policy rate was 4.00% and Korea's policy rate was 3.00%. Read with the frameworks of Lessons 13 and 17, this is an environment where a high discount rate presses down the multiple knob, a headwind for growth stocks and long-term bonds with a large share of distant future earnings. Conversely, in the Macro Map's environment score, banks came out 'somewhat favorable' thanks to higher interest rates (the very score dissected in Lesson 36).
Note: 10-year yield in the 5% range persisting → headwind for growth stocks and long-term bonds, tailwind for banks and insurers. If rates fall more than 0.3 percentage points in a month, re-check whether the score ranking changes.
Example 2 · The exchange rate and exports: Korea's own wind
The USD/KRW exchange rate was KRW 1,349, down 12.3% over three months, so the won clearly strengthened. In the same period, Korea's export growth (export value index, August 2026) was 75.8% year over year, the highest in the past five years. Read with Lessons 25 and 26, the export boom pushes up the earnings knob, while the strong won somewhat trims exporters' won-translated earnings. When two winds blow in opposite directions, the key is which is bigger, and this time the power of semiconductor exports, where volume and price grew together, was far bigger.
Note: export boom (earnings ↑) vs strong won (translated earnings ↓), exports currently winning. In the trade statistics released on the 1st of next month, check whether semiconductor growth slows, and whether foreign investor turns to buying.
Example 3 · Calendar and sentiment: winds coming next week
The was 15.31, in the bottom 23% of the past five years, meaning the market was calm. But the KOSPI margin loan balance grew about 16%, from about KRW 22.6 trillion on April 1, 2026 to about KRW 26.1 trillion on October 1, so debt-fueled investing kept steadily building up. The calendar had US September CPI on Oct 14, the BOK Monetary Policy Board on Oct 22 and the FOMC on Oct 28. Read with Lesson 39, 'calm sentiment + growing debt' is a combination in which swings can get bigger if a big surprise comes.
Note: write down the Oct 14 CPI expectation the day before the release. If higher than expected, rates and the dollar ↑ → the headwind in Example 1 grows. Also check whether the VIX breaks 20 and which way the margin loan balance is heading.
For stocks: good notes and bad notes
| Bad note | Good note | Why is it better? |
|---|---|---|
| "Rates look like they'll rise, be careful" | "If the 10-year goes above 5.3%, review growth stock weight" | It has a numerical condition to check |
| "Semiconductors look good" | "If semiconductor export growth slows for two months in a row, revisit the sector score" | It states what would change your mind |
| "Expecting a crash next week" | "CPI expected 3.2%; if above 3.5%, check interest rates first" | It writes down the expected figure and the order of response instead of a forecast |
What good notes have in common is a . If you write in the form "when this number appears, I look at this again", you can respond in the order you set in advance without panicking even if the market moves differently than expected. As you learned in Lesson 42, forecasts are often wrong, but you can set the order of response in advance. A note is not a signal for buying or selling a specific stock; it is a record that reveals what assumptions your judgment rests on.
It isn't always so. The checklist's seven items and their order are an educational framework for not missing the macro environment, and they do not reflect company earnings, price levels, or an individual's investment horizon and risk tolerance. The interpretations in the examples apply the principles learned so far to that week's data and are not buy or sell recommendations.

✓What we learned today
- When you look at economic news, always ask two things: does it move the earnings knob or the multiple knob (Lesson 1)? And the gap from expectations matters more than the number itself (Lesson 20).
- Each week, look at the seven items from the big winds to the small winds: market results → interest rates → exchange rate and foreign investors → commodities → this week's calendar → investor sentiment → sector map.
- We look at interest rates first because they are the benchmark (discount rate) for all asset prices. Once you know the direction of interest rates and the exchange rate, you have a frame for interpreting the rest of the numbers.
- The output of the routine is not a conclusion but a one-line note containing a 'check condition'. Next week, begin by checking whether that condition came true.
- The checklist is not a forecasting tool; it is a tool for not missing things. Even when a forecast is wrong, having an order of response reduces the shaking (Lesson 42).
You've finished all 43 Economics lessons. Now that you can read the winds of the whole market, the next step is to check for yourself whether 'the company I bought is sound'. In the next course, 'Reading Financial Statements', you'll learn how to read the balance sheet, income statement and cash flow statement using a fictional company, Robin Bakery.
Quiz5-question quiz
Pick an answer and it's graded right away with an explanation.
Q1. What are the two basic questions this course has asked throughout when looking at economic news?
Since stock price = earnings × multiple (Lesson 1), first look at which knob the news moves, and since the market reacts to the gap from expectations rather than the number itself (Lesson 20), look at the surprise as well.
Q2. What is the main reason the checklist looks at interest rates before the exchange rate and commodities?
Interest rates are the discount rate that converts future earnings into today's value (Lesson 17). Knowing the direction of rates makes it easier to interpret other moves, such as why growth stocks were weak.
Q3. The won is strengthening while Korean exports are growing strongly. Which is the correct reading of exporters' earnings knob?
Growth in export volume and prices pushes earnings up (Lesson 26), while a strong won converts the same dollar revenue into fewer won (Lesson 25). When two winds blow in opposite directions, the key is which is bigger.
Q4. The VIX is low, but the margin loan balance keeps growing. What is the most appropriate reading of this combination from the perspective of Lesson 39?
A low VIX means things are calm right now, and a growing margin loan balance increases the chance of chain selling such as forced liquidation when prices fall. But there is no 'certainly'. It is better to write it down as a check condition.
Q5. What is the best note to leave after finishing the weekly checklist?
A good note has a numerical check condition and an order of response. Instead of a forecast or a buy/sell decision, writing down what you will look at again if something appears makes next week's review easier (Lesson 42).
