FundSpec fundamental metrics
Each metric is computed from the company's filings and ranked against every company FundSpec covers; the percentile is the share of covered companies with a lower value.
Liquidity
| Metric | Value | Percentile | What it measures |
|---|---|---|---|
| Cash Ratio | 0.33 | 54th | Calculated as the ratio of Cash and cash equivalents / Current liabilities. This metric calculates the company's ability to repay its short-term debt |
| Current Ratio | 1.95 | 68th | Calculated as the ratio of Current Assets / Current Liabilities. The higher the current ratio, the more capable the company is of paying its obligations |
| Quick Ratio | 0.68 | 43rd | Calculated as the ratio of (Cash + Marketable Securities + Accounts Receivable) / Current Liabilities. The quick ratio is a measure of how well a company can meet its short-term financial liabilities. |
Leverage
| Metric | Value | Percentile | What it measures |
|---|---|---|---|
| Debt/Assets | 0.23 | 68th | Calculated as the ratio of Short-Term Debt + Long-Term Debt / Total Assets. The higher the ratio, the higher the degree of leverage, and consequently, financial risk |
| Debt/Equity | 0.39 | 58th | Calculated as the ratio of Total Liabilities / Shareholders' Equity. The ratio indicates how much debt a company is using to finance its assets relative to the amount of value represented in shareholders’ equity |
| Degree of Financial Leverage | 1.68 | 87th | Calculated as the ratio of Percentage change in EPS / Percentage change in EBIT. A higher degree of financial leverage means that the company has more volatile EPS. |
| Long Term Debt/Long Term Capital | 0.02 | 11th | Calculated as Long-Term Debt / (Long-Term Debt + Shareholders' Equity). The ratio is an indicator of the company's leverage |
Profitability
| Metric | Value | Percentile | What it measures |
|---|---|---|---|
| Free Cashflow Margin Pct | 20.1% | 82nd | Calculated as the ratio of Free Cashflow from Operating Activities / Net Sales. It measures how much per dollar of revenue the company is able to convert into free cash flow. |
| Gross Margin Pct | 74.0% | 86th | Calculated as the ratio of Revenue - Cost of Goods Sold (COGS) / Revenue. The gross margin represents the percent of total sales revenue that the company retains after incurring the direct costs associated with producing the goods and services sold by a company. |
| Operating Margin Pct | 7.3% | 58th | Calculated as the ratio of (Revenue - (Cost of Goods Sold + Labour + Sales, General & Administrative)) / Revenue. Operating margins are important because they measure efficiency. The higher the operating margin, the more profitable a company's core business is. |
| PreTax Margin Pct | 4.3% | 51st | Calculated as the ratio of (Gross profit - (Operating Expense + Interest Expense)) / Revenue. The pretax profit margin enables profitability to be compared across companies with significant differences in size, scale, capital structure and tax rates. |
| Return on Assets Pct | 1.1% | 59th | Calculated as the ratio of Net Income / Total Assets. It is an indicator of how efficient the company is at using its assets to generate earnings. |
| Return on Equity Pct | 1.9% | 48th | Calculated as the ratio of Net Income / Shareholders' equity. It is a measure of how much profit a company generates with the money shareholders have invested. |
| Return on Invested Capital Pct | 2.3% | 47th | Calculated as the ratio of (Net Income - Dividends) / (Debt + Equity). It is a measure of how efficient the company is at allocating the capital under its control to profitable investments. |
Cashflow
| Metric | Value | Percentile | What it measures |
|---|---|---|---|
| FCF Pct Growth | -10.1% | 35th | The Free Cash Flow growth rate over the trailing twelve months (TTM) |
| FCF Pct Growth 3 year CAGR | 95.1% | 74th | The Free Cash Flow compound annual growth rate (CAGR) over the past 3 years |
| FCF Pct Growth 5 year CAGR | -3.3% | 35th | The Free Cash Flow compound annual growth rate (CAGR) over the past 5 years |
| FCF Return on Assets Pct | 6.8% | 76th | Calculated as the ratio of Cashflow from Operations / Total Assets. A high cash return on assets means a company is generating more cash flow from every asset dollar |
| Operating Cashflow Pct Growth | -8.4% | 36th | The Operating Cashflow growth rate over the trailing twelve months (TTM) |
| Operating Cashflow Pct Growth 3 year CAGR (FY) | 18.2% | 71st | The Operating Cashflow compound annual growth rate (CAGR) over the past 3 years |
| Operating Cashflow Pct Growth 5 year CAGR (FY) | -1.6% | 40th | The Operating Cashflow compound annual growth rate (CAGR) over the past 5 years |
