Definition
Instability Index of Earnings refers to a financial metric that quantifies the fluctuation or variation between a company’s actual earning results and its expected or trend profits over a specified period. It is an indicator of how erratic a company’s profits are relative to a stable expected growth path. A higher instability index suggests more volatility and potential unpredictability in the company’s profitability, which could signal greater risk to investors and stakeholders.
Examples
-
Company A: Suppose Company A has actual quarterly profits over a year as follows: $10M, $12M, $8M, and $14M, with a trend profit estimated at $11M per quarter. The deviations from the trend ($11M) are $-1M, $1M, $-3M, and $3M, respectively. This results in an instability index indicating notable earnings volatility.
-
Company B: If Company B shows actual annual profits of $20M, $19M, $21M, and $20M with a trend profit of $20M, the deviations are minimal ($-1M, $-1M, $1M, $0M), resulting in a lower instability index that denotes more stable profitability.
