The Kenya 30 Index (KEN30) is a rules-based, blockchain-native benchmark designed to reference the performance of thirty leading companies listed on the Nairobi Securities Exchange (NSE).
The benchmark is constructed using a deterministic weighting methodology, with constituent composition and weights maintained on-chain through a registry contract.
KEN30 is classified as a price return equity index.
The objective of KEN30 is to provide a transparent and programmable benchmark representing the performance of leading publicly listed companies in Kenya.
The index is designed for integration into financial infrastructure, analytics systems, and digital trading environments.
KEN30 does not represent ownership of underlying securities and does not function as an investment product.
The index universe consists of companies listed on the Nairobi Securities Exchange.
Eligible companies must meet defined criteria related to:
• Market capitalization
• Trading liquidity
• Listing status
• Operational continuity
Market capitalization assessments may incorporate free-float adjustments where applicable to reflect the proportion of shares available for public trading.
The Kenya 30 Index includes thirty companies selected based on a combination of market capitalization and liquidity.
Selection criteria include:
• Active listing on the Nairobi Securities Exchange
• Sufficient free-float market capitalization
• Adequate average daily trading volume
• Consistent trading activity
Liquidity may be assessed using metrics such as average daily trading volume, turnover ratio, and frequency of trading activity.
Companies may be excluded if they are suspended, delisted, or fail to meet liquidity thresholds.
In cases where multiple constituents exhibit similar eligibility characteristics, selection priority may be determined based on higher liquidity metrics or consistent trading activity.
The index maintains a fixed number of thirty constituents.
The number of constituents does not change unless modified through governance procedures.
KEN30 uses a deterministic fixed-weight structure.
The index is divided into two tiers:
• Ten constituents weighted at 334 basis points each
• Twenty constituents weighted at 333 basis points each
Total weight:
(10 × 334) + (20 × 333) = 10000 basis points
The registry enforces that total weight equals 10000 basis points at all times.
Weights are assigned based on relative market importance, considering:
• Market capitalization
• Liquidity profile
• Sector representation
Final weights are encoded in the on-chain registry and remain fixed between rebalancing events.
Let:
P_i = price of constituent i
W_i = weight of constituent i
N = number of constituents (30)
Index Value (KEN30_t):
KEN30_t = ( Σ (P_i × W_i) ) / TOTAL_WEIGHT
Where:
TOTAL_WEIGHT = 10000
The index is initialized with a base value of:
1.000000000000000000
All subsequent index values represent proportional changes relative to this base level.
Prices for each constituent are sourced from:
• Nairobi Securities Exchange official data
• Licensed market data providers
• Verified secondary data sources where applicable
Prices are denominated in Kenyan Shillings (KES).
Benchmark calculations reference official market data aligned with Nairobi Securities Exchange trading hours.
KEN30 reflects price movements in local currency terms.
The index does not incorporate foreign exchange adjustments.
The index may undergo periodic rebalancing to maintain relevance and accuracy.
Rebalancing actions may include:
• Adjustment of constituent weights
• Replacement of constituents
• Updates to eligibility criteria
Buffer rules may be applied during rebalancing to minimize unnecessary turnover. Existing constituents may be retained unless they fall materially below eligibility thresholds.
Rebalancing is executed through governance procedures and subject to timelock delay.
Rebalancing changes become effective upon execution of governance-approved registry updates following timelock delay.
The index composition and methodology may be reviewed:
• Quarterly
• Semi-annually
• On an event-driven basis
Reviews assess market developments and constituent eligibility.
The index may adjust for corporate actions affecting constituent securities.
Relevant corporate actions include:
• Stock splits
• Reverse splits
• Mergers and acquisitions
• Delistings
• Ticker changes
• Rights issues
Adjustments are implemented through registry updates via governance.
If a constituent is temporarily suspended from trading:
• The last available traded price may be used
• If suspension persists, the constituent may be removed through governance
If market data for a constituent is unavailable:
• The most recent valid price may be used temporarily
• Persistent data gaps may trigger governance intervention
All benchmark updates must satisfy validation rules:
• Oracle quorum requirements
• Minimum update interval
• Maximum allowed deviation thresholds
• Data freshness constraints
Invalid submissions are rejected by the protocol.
Index maintenance includes:
• Monitoring constituent eligibility
• Ensuring data integrity
• Updating methodology when required
All changes are executed through governance procedures.
The full index methodology is stored on-chain within the constituent registry.
This enables:
• Public verification of index composition
• Independent validation of weights
• Transparent tracking of methodology updates
All methodology updates are version-controlled and recorded on-chain through registry versioning.
All methodology changes are governed through a timelock-controlled system.
Governance actions include:
• Registry updates
• Rebalancing execution
• Parameter adjustments
No changes can be executed instantly.
The benchmark operates under a rules-based methodology and does not permit discretionary manual overrides outside of governance-controlled procedures.
The index is subject to certain limitations:
• Dependence on data availability
• Market liquidity constraints
• Oracle submission timing
These limitations are inherent to both traditional and digital benchmark systems.
In the event of extreme price dislocation or data anomalies, governance may temporarily suspend updates or apply corrective measures to preserve benchmark continuity.
KEN30 is classified as:
• A price return equity index
• A benchmark reference instrument
• A programmable digital benchmark
KEN30 is not classified as:
• A financial security
• An exchange-traded fund
• A derivative instrument
Methodology updates may be introduced to reflect market evolution.
All updates:
• Must be approved through governance
• Must pass timelock delay
• Must be recorded on-chain
