Stability Scoring – How Well You Can Sleep with That Stock

The Stability label (Unstable / Moderate / Stable) doesn't evaluate company quality, but the predictability of its development. A stable company has consistent results and its stock fluctuates less – this is especially important for more conservative investors.

Why Stability Matters

Stability is not the same as quality or profitability. A company can be highly profitable but very volatile (typically mining companies). Another may have average results but completely predictable (utilities).

For investors, stability means:

• Less portfolio fluctuation – Stable stocks fluctuate less, which is important for peace of mind and for those who may need to sell at an inconvenient time
• More predictable dividends – Companies with stable results can more easily maintain and increase dividends
• Lower risk of "surprises" – Lower probability of sudden results collapse

What We Evaluate

Beta – Measures how much the stock moves compared to the overall market. Beta of 1 means the stock tracks the market. Beta higher than 1 means larger swings (when the market rises 10%, the stock rises more, and vice versa). Beta lower than 1 means less sensitivity to market movements. Ideal beta depends on the sector – we expect low beta from utilities, higher from technology.

Revenue Volatility – How much company revenue fluctuates year to year. A company whose revenue grows by a similar percentage each year is more stable than one whose revenue grows 30% one year and falls 20% the next.

EPS Volatility – Same principle as revenue, but for Earnings Per Share. Profits tend to be more volatile than revenue due to operating leverage – a small change in revenue can result in a large change in profit.

Profitable Years Share – How many years over the tracked period the company was profitable. A company that is profitable every year is more predictable than one alternating between profits and losses.

Sector Differences

Different sectors have naturally different volatility:

• Utilities and defensive consumer goods – We expect high stability. People pay for electricity and buy basic groceries regardless of the economic cycle
• Technology – Higher volatility is acceptable due to growth potential
• Cyclical sectors (energy, materials, industrials) – Highest tolerance for volatility. These businesses are inherently dependent on the economic cycle and commodity prices
• Financial sector – Medium volatility, results depend on interest rates and economy

Scoring accounts for these differences – an energy sector company won't be penalized for volatility that would be alarming for a utility.

How to Interpret Results

Stability vs. Risk

It's important to distinguish:

• Stable ≠ safe – Even a stable company can face structural problems or be overpriced
• Unstable ≠ bad – A volatile company may offer excellent growth potential. For a long-term investor with steady nerves, it may be more interesting than a "boring" stable stock

Stability scoring helps you understand what fluctuations to expect, not whether the company is a good investment.
