Lesson: Understanding Risk & Reward Scores – A Beginner’s Guide

Welcome to the world of stock analysis. It can sometimes feel like you need a PhD in finance just to open a trading platform. But we are here to make it simple.

Imagine you are buying a house. You wouldn't just walk in and hand over your money. You look at the potential for it to go up in value (the Reward) and you look at how much it might cost you if things go wrong (the Risk).

Openbook provides two special scorecards to help you do exactly that. Think of these scores as a "health check" for a stock. They don't tell you what to buy, but they help you understand how a company behaves.

What Are the Openbook Scores?

Openbook provides two specific scores for every stock you look at:

1. The Reward Rating: This is a number between 0 and 100. It measures how much potential upside the stock has. Think of this as the "Upside Potential."
2. The Risk Rating: This is also a number between 0 and 100. It measures how vulnerable the stock is to losing money. Think of this as the "Downside Vulnerability."

Important Note: These scores are educational tools. They are designed to help you understand a stock at a glance, but they are not buy or sell recommendations. They are data points, not crystal balls.

An Example

Let’s say you look at a company and see:

• Reward Score: 75 (High)
• Risk Score: 40 (Low)

This tells you that this company has the characteristics of a stock that could go up significantly. It doesn't mean you should buy it, but it tells you that the quantitative factors we track are favorable.

How the Reward Rating Works

The Reward Rating tries to answer one question: How much could this stock grow?

To answer this, the system looks at five different ingredients, each with a different "weight" or importance. It’s like a recipe. Some ingredients matter more than others.

1. Growth (25% Weight)

This measures if the company is getting bigger and more profitable over time.

• The Mechanics: It looks at revenue, net income, and cash flow.
• What a High Score Means: The company is growing fast. Just like a plant that is shooting up in height, a high score goes to companies that are expanding their earnings rapidly.

2. Momentum (20% Weight)

This measures the current trend and how investors are feeling about the stock right now.

• The Mechanics: It looks at the returns over the last 1 year, 6 months, and 3 months.
• What a High Score Means: The stock is "hot." Investors are buying it, and the price is moving up. Historically, stocks that have momentum tend to keep moving up for a while.

3. Profitability (25% Weight)

This measures how good the company is at turning a dollar of revenue into a dollar of profit.

• The Mechanics: It looks at margins (how much profit you keep after costs) and how efficiently they use their assets (like factories or cash).
• What a High Score Means: The company is a "cash machine." They have high profit margins and use their money efficiently to generate more money.

4. Valuation (20% Weight)

This measures if the stock is cheap or expensive compared to its value.

• The Mechanics: It looks at ratios like the Price-to-Earnings ratio (P/E).
• What a High Score Means: The stock is a "bargain." It means the stock is trading at a lower price relative to its earnings than the average stock in the market. This is often called being a "value stock."

5. Size Factor (10% Weight)

This looks at how big the company is (Market Capitalization).

• The Mechanics: It looks at the total value of all the company's shares.
• What a High Score Means: Smaller companies. Historically, smaller companies tend to offer higher growth potential because they have more room to grow, though they can be riskier.

How the Risk Rating Works

The Risk Rating tries to answer a different question: How much could this stock hurt me?

It looks at four specific areas to see if the company is stable or fragile.

1. Financial Solvency (35% Weight)

This is the most important factor for risk. It measures if the company has enough money to pay its debts.

• The Mechanics: It looks at debt levels and how easily the company can pay interest on that debt.
• What a High Risk Score Means: The company is "heavy" with debt. They have a lot of loans, and it might be hard for them to pay the interest if business slows down.

2. Operational Quality (25% Weight)

This measures how stable the company's business model is.

• The Mechanics: It looks at profit margins and cash flow.
• What a High Risk Score Means: The company is "thin." They might be making profit, but it’s very small or unstable. If they have a bad month, they could lose money.

3. Volatility (25% Weight)

This measures how much the stock price jumps around.

• The Mechanics: It looks at how much the price fluctuates historically and how low the price has ever gone.
• What a High Risk Score Means: The stock is a "rollercoaster." The price swings wildly up and down. This creates anxiety for investors and can lead to large losses if you sell at the bottom.

4. Size Factor (15% Weight)

Similar to the Reward rating, this looks at size.

• The Mechanics: It looks at Market Capitalization.
• What a High Risk Score Means: Smaller companies. Smaller companies have a higher chance of failing completely compared to massive corporations like Apple or Microsoft.

How to Read the Numbers

Once you have the scores, you need to know what they mean. We rate them in four levels based on how they compare to other stocks in the market.

The Golden Rule:

• For Reward, you want a high number.
• For Risk, you want a low number.

How Scores Are Calculated

You might wonder how a computer decides on a score. It’s a weighted average.

1. Data Collection: The computer pulls raw numbers from financial reports.
2. Comparison: It puts the company in a "percentile." If a company is growing faster than 90% of its peers, it gets a high score for that factor.
3. Weighting: Some factors count more than others. For example, Profitability is 25% of the Reward score, while Size is only 10%. The computer does the math to get a final score out of 100.

Missing Data: If a company doesn't report certain data, the system defaults to a neutral score of 50 for that specific factor. This is why you should always check the Data Coverage percentage.

Understanding Data Coverage

Under the score, you might see a number like "85%." This tells you how reliable the score is.

• 90%+ Coverage: The score is based on real data. You can trust it.
• 60% Coverage: Some data is missing. The score is a bit of a guess. You should interpret it with caution.

How to Use These Scores

These scores are powerful, but they must be used as a compass, not a map. They point you in a direction, but you must drive the car.

✅ DO Use Them To:

• Get a Snapshot: Quickly see if a stock looks like a "growth" stock or a "value" stock.
• Compare: Compare two different companies to see which one has stronger fundamentals.
• Identify Research: If a stock has a high Reward score, it’s a good candidate to dig deeper into the financial statements.
• Understand Drivers: See why a specific stock is rated the way it is. (e.g., "Ah, this stock has a high Reward score because the Momentum is strong.")

❌ DON'T Use Them To:

• Buy or Sell Blindly: Do not make a decision based solely on a score of 90.
• Expect Guarantees: A high Reward score means the potential is there. It does not mean the stock will go up. Markets are unpredictable.
• Ignore the Human Element: Scores ignore management quality, brand reputation, and competitive moats. A company could have a perfect score but still fail due to bad leadership.
• Skip Due Diligence: You must read the news and the financial reports yourself.

Summary

• Reward Rating: Measures upside potential (Growth, Momentum, Profitability, Valuation, Size).
• Risk Rating: Measures downside vulnerability (Solvency, Operations, Volatility, Size).
• The Scale: Scores range from 0 to 100. High is good for Reward; Low is good for Risk.
• Educational Only: These are tools to help you learn, not financial advice.
• The Human Factor: Always do your own research before investing.
