OMER average PE ratio chart
What this chart measures
The Historical Valuation Regime chart shows where the stock's current valuation sits relative to its own historical valuation range over the selected lookback period.
This is a history-relative tool, not a market-relative percentile. It does not compare the stock to other companies. Instead, it compares each historical valuation reading to the stock's own past readings.
Percentile logic
The threshold lines are calculated them from the stock's real historical values using percentile interpolation. That is why some colored bands are narrow while others are wide: the band widths reflect how the stock actually traded through time.
Regime map
| Historical percentile | Regime | Chart meaning |
|---|---|---|
| 0-10 | Historically Low | Deep cheap zone |
| >10-25 | Below Average | Cheap relative to history |
| >25-75 | Average | Within the normal historical range |
| >75-90 | Above Average | Expensive relative to history |
| >90-100 | Historically High | Extreme or stretched valuation |
How to read each part
| Chart element | What it tells you |
|---|---|
| Main line | The actual historical valuation values over time for the selected metric. |
| Dashed horizontal lines | The stock's computed P10, P25, Median, P75, and P90 thresholds for the selected period. |
| Colored bands | The historical valuation zones between those thresholds. |
| Metric boxes | Current ratio, historical median, current percentile, and current regime. |
| Timeline strip | A condensed regime history showing how the stock moved between cheap, fair, and expensive states across each observation. |
Important metric definitions
Current Percentile is the percentile rank of the latest valid historical observation within the selected lookback range.
Current Regime is assigned directly from the latest observation's percentile bucket using the fixed 10 / 25 / 75 / 90 cutoffs shown above.
How to use it well
This chart is most useful for answering a narrow question: Is this stock trading high, low, or normal relative to its own history? It works best alongside growth, profitability, and forward-looking business analysis, because a stock can deserve a higher or lower regime if its business quality has changed.
