- Sharpe ratio
-
Average excess return divided by return volatility, annualized
when labeled. A larger historical value does not establish
repeatability.
- Total return
-
Cumulative change over the stated evaluation period, including
only the cost and income assumptions explicitly supplied.
- Annualized return
-
A historical return expressed as an annual growth rate. It is not
a forecast of the next year.
- Worst decline
-
The largest peak-to-trough loss in the tested return series, also
called maximum drawdown.
- Hit rate
-
The share of evaluated outcomes meeting the stated model target.
Interpret it with its target, baseline and sample size.
-
Edge over baseline
-
The reported difference between a model result and its simple
comparison, measured on the same target and period. The metric
definition must be supplied to interpret the difference.
-
Classification quality
-
Area under the receiver operating characteristic curve: how well a
binary score separates the two outcome classes across thresholds.
This is distinct from accuracy.
- Training error
-
Prediction error measured on the training data. It does not
measure performance on later unseen observations.
-
Climate persistence
-
Estimated probability that a market-climate state remains in that
state for the next modeled interval.
-
Climate switch probability
-
Estimated probability of a change in the modeled market-climate
state.
-
Breakout probability
-
The reported historical rate or modeled probability of a qualified
breakout under the supplied setup definition.
- Target rate
-
The historical share of comparable qualified structures that
reached their measured target.
-
Reward for each unit of risk
-
Estimated distance to a target divided by distance to the setup’s
risk boundary. Costs and execution can change the realized ratio.
-
Failure probability
-
The model’s estimated chance that a price move fails under its
stated definition. The target and horizon must be known to
interpret it.
-
Post-earnings response
-
Price behavior following dated earnings events, compared with
similar historical observations.
-
Earnings-to-cash quality
-
A supporting measure of how consistently reported earnings convert
into cash flow. It does not establish entry timing.
-
Cash-conversion risk
-
A supporting assessment of weak or unstable conversion of reported
earnings into cash.
- Macro Context
-
Dated economic-release and interest-rate observations that help
explain the environment surrounding a model reading.
-
Intraday order-flow pressure
-
Trade or order-book imbalance over short intervals and its
measured relationship with later price changes.
-
Variation explained
-
The share of observed variation captured by the stated statistical
relationship. It is not a causal claim.
- Forward horizon
-
The number of future intervals over which an outcome is measured.
Interpretation depends on the interval length.
- Quality score
-
A model-defined supporting score of company cash-flow quality. Its
inputs, scale and limits should be supplied with the reading.
- Risk score
-
A model-defined supporting assessment of cash-conversion risk. It
is not a probability of investment loss.
- Red flags
-
The count of checks that met the published model’s risk-flag
criteria.
- Repeated trials
-
The number of variants considered when selecting a result. Testing
many variants increases the chance of selecting a lucky result.
- Minimum history
-
The estimated observation history needed for the stated inference
threshold. Dependent observations may provide less information
than their raw count.
- Modeled exposure
-
The aggregate invested share in the published public research
comparison. It describes the simulation’s exposure.
- Cash reserve
-
The aggregate share assigned to cash in the public research
comparison.
- Spot
-
The reference price of the underlying security at the option
snapshot time.
- Contribution
-
A supplied component’s influence on the combined ticker reading.
Without the publisher’s scale, contributions should not be
compared across models.
