# Indices & Token Groups

> Data Dictionary — indices and token groups terms with definitions, formulas, units, and source commands

Index methodology, returns, AUM, and group-level performance metrics.

***

### Index Value

Current calculated value of the index based on constituent weights and prices.

```
Formula   Σ(Weight_i × Price_i) × Divisor
Unit      Points / USD
Example   1,250.45
```

**Related** · AUM, Index Return

**Used in** · [`IOV`](/docs/docs/core-concepts/commands/by-object/index#iov-index-overview) · [`IPF`](/docs/docs/core-concepts/commands/by-object/index#ipf-index-performance)

***

### Index Methodology

Published document describing how an index is constructed, weighted, and rebalanced.

```
Unit      Document
Example   CoinDesk 20 Methodology v3.1
```

**Related** · Weighting Method, Rebalancing Event

**Used in** · [`IOV`](/docs/docs/core-concepts/commands/by-object/index#iov-index-overview)

***

### Weighting Method

Methodology used to assign constituent weights (market-cap, equal, custom).

```
Unit      Category
Example   Market-cap weighted
```

**Related** · Constituent Weight, Methodology

**Used in** · [`IOV`](/docs/docs/core-concepts/commands/by-object/index#iov-index-overview) · [`IXSC`](/docs/docs/core-concepts/commands/by-object/cross-object#ixsc-index-screening)

***

### Index Constituents

List of tokens included in the index with their assigned weights.

```
Unit      Token × Weight
Example   BTC: 40%, ETH: 25%
```

**Related** · Rebalancing, Weight

**Used in** · [`IOV`](/docs/docs/core-concepts/commands/by-object/index#iov-index-overview)

***

### Constituent Weight

Proportion of the index allocated to a single token.

```
Formula   Methodology-defined (market cap, equal, custom)
Unit      %
Example   BTC: 40%
```

**Related** · Index Constituents, Weighting Method

**Used in** · [`IOV`](/docs/docs/core-concepts/commands/by-object/index#iov-index-overview)

***

### Rebalancing Event

Scheduled index reconstitution: additions, removals, and weight changes.

```
Unit      Event
Example   Q1 2026: +ONDO, −FTT
```

**Related** · Index Constituents, Review Calendar

**Used in** · [`IOV`](/docs/docs/core-concepts/commands/by-object/index#iov-index-overview)

***

### Index Return (Timeframe)

Percentage change in index value over a period.

```
Formula   (Value_end − Value_start) / Value_start × 100
Unit      %
Example   +8.5% (YTD)
```

**Related** · Index Value, Annual Return

**Used in** · [`IPF`](/docs/docs/core-concepts/commands/by-object/index#ipf-index-performance)

***

### Annual Return

Calendar-year total return of the index.

```
Formula   (Dec 31 Value − Jan 1 Value) / Jan 1 Value × 100
Unit      %
Example   2025: +65.2%
```

**Related** · Monthly Return, Index Return

**Used in** · [`IPF`](/docs/docs/core-concepts/commands/by-object/index#ipf-index-performance)

***

### Monthly Return

Calendar-month total return of the index.

```
Formula   (Month End − Month Start) / Month Start × 100
Unit      %
Example   Jan 2026: +12.3%
```

**Related** · Annual Return, Seasonality

**Used in** · [`IPF`](/docs/docs/core-concepts/commands/by-object/index#ipf-index-performance)

***

### Calendar Pattern

Historical best/worst performing months or quarters for an index.

```
Formula   Mean return per calendar month
Unit      % per month
Example   Best: Jan (+15%), Worst: Jun (−8%)
```

**Related** · Seasonality, Monthly Return

**Used in** · [`IPF`](/docs/docs/core-concepts/commands/by-object/index#ipf-index-performance)

***

### Index Comparison

Side-by-side performance overlay of multiple indices or tokens.

```
Formula   Normalized value return %
Unit      %
Example   BTC Index +45% vs DeFi Index +62%
```

**Related** · Index Value, Benchmark

**Used in** · [`ICP`](/docs/docs/core-concepts/commands/by-object/index#icp-index-comparison)

***

### Similar / Related Indices

Related indices identified by overlapping constituents, methodology, or asset coverage.

```
Unit      Index[]
Example   CoinDesk 20, FTSE Galaxy Crypto Index
```

**Related** · Index Comparison, Index Constituents

**Used in** · [`IOV`](/docs/docs/core-concepts/commands/by-object/index#iov-index-overview)

***

### Group Major Tokens (80% MC)

Tokens that comprise at least 80% of a token group's total market cap.

```
Formula   Largest tokens until cumulative MC ≥ 80%
Unit      Token[]
Example   BTC, ETH, SOL (= 82% of group MC)
```

**Related** · Token Group, Constituent Weight

**Used in** · [`GRA`](/docs/docs/core-concepts/commands/by-object/token-groups#gra-group-analytics)
