Value + Momentum Combo Strategy
Blend cheap valuation with positive price momentum
Value + Momentum Combo Strategy is a systematic factor portfolio template that scores securities with value ratios and prior return momentum, converts ranks into controlled positions, and manages factor crowding with sector caps, factor-balance bands, and momentum crash de-risking. - Jegadeesh and Titman

Multi-factor systems can look diversified while still sharing hidden exposures; sector caps, factor-balance bands, and momentum crash de-risking must be measured explicitly.
В: What is the core idea behind Value + Momentum Combo Strategy?
The strategy combines value ratios and prior return momentum, ranks securities using combined value rank and momentum rank, enters when a security is cheap relative to peers while its price trend remains positive, and exits when value score deteriorates, momentum breaks, or the combined rank leaves the target bucket.
В: When does Value + Momentum Combo Strategy usually fail?
It usually fails when factor signals become crowded, accounting inputs are biased, turnover overwhelms the edge, or the chosen factors stop being rewarded.
В: How should Value + Momentum Combo Strategy be backtested?
Backtest it with point-in-time fundamentals, delisting-aware universes, realistic rebalance calendars, transaction costs, turnover limits, and exposure attribution.
Как работает эта стратегия
5-этапный поток решений: от анализа рынка до управления сделкой
1
Factor Universe
Define eligible securities
Screen the universe before applying value ratios and prior return momentum
Remove names with unreliable fundamentals, stale prices, low liquidity, or survivorship-biased data
Normalize accounting dates, market caps, sectors, and currency exposure before ranking
2
Factor Scoring
Rank expected return drivers
Compute combined value rank and momentum rank with point-in-time inputs
Use value traps, negative earnings quality, and weakening relative strength filters to reject crowded or structurally weak factor exposure
Check whether factor signals remain stable after sector, size, and liquidity constraints
3
Portfolio Construction
Balance return and exposure
Convert scores into weights without letting one factor dominate the book
Limit unintended beta, sector, country, and capitalization tilts
Verify that turnover is economically justified after costs and tax assumptions
4
Rebalance
Enter, rotate, and remove
Enter when Composite = z(Value Rank) + z(Momentum Rank) produces a tested positive score
Prefer entries where a security is cheap relative to peers while its price trend remains positive
Exit or reduce exposure when value score deteriorates, momentum breaks, or the combined rank leaves the target bucket
5
Exposure Control
Stress-test factor risk
Define sector caps, factor-balance bands, and momentum crash de-risking before the first rebalance
Stress factor crashes, valuation regime shifts, stale fundamentals, and liquidity exits
Stop deploying the model when live factor behavior diverges from the tested sample
Справочник компонентов стратегии
- Value + Momentum Combo Strategy
- Value + Momentum Combo Strategy is a systematic factor portfolio template that scores securities with value ratios and prior return momentum, converts ranks into controlled positions, and manages factor crowding with sector caps, factor-balance bands, and momentum crash de-risking.
- Value + Momentum Combo Strategy Market Suitability
- The Value + Momentum Combo Strategy strategy works best in Broad liquid universes where value ratios and prior return momentum can be measured with point-in-time data.. Portfolio workflows that can rebalance systematically while controlling turnover, sectors, beta, and liquidity.. Regimes where factor premia are diversified rather than concentrated in one crowded trade.. Traders should avoid using this strategy in Small universes where factor rankings are dominated by accounting noise or stale prices.. Crowded factor unwind periods where many strategies hold similar long and short books.. Backtests with look-ahead fundamentals, missing delisting data, or unrealistic execution assumptions.. The risk level is categorized as HIGH. Multi-factor systems can look diversified while still sharing hidden exposures; sector caps, factor-balance bands, and momentum crash de-risking must be measured explicitly.
- What is the core idea behind Value + Momentum Combo Strategy?
- The strategy combines value ratios and prior return momentum, ranks securities using combined value rank and momentum rank, enters when a security is cheap relative to peers while its price trend remains positive, and exits when value score deteriorates, momentum breaks, or the combined rank leaves the target bucket.

- Backtest it with point-in-time fundamentals, delisting-aware universes, realistic rebalance calendars, transaction costs, turnover limits, and exposure attribution.
- value ratios and prior return momentum
- value ratios and prior return momentum defines the return drivers the model attempts to harvest before portfolio constraints are applied. Formula: Composite = z(Value Rank) + z(Momentum Rank)
- Point-in-Time Data
- Point-in-time data prevents the backtest from using financial statements or index membership information before it was actually available. Formula: Use known values only
- Eligible Universe
- The eligible universe defines which securities can be scored and traded, reducing noise from illiquid or incomplete records. Formula: Liquidity + data filters
- combined value rank and momentum rank
- combined value rank and momentum rank converts raw factor data into comparable scores that can drive weights, inclusions, and exclusions. Formula: Composite factor rank
- value traps, negative earnings quality, and weakening relative strength filters
- value traps, negative earnings quality, and weakening relative strength filters keeps the model from allocating to securities whose factor score is not robust enough for a live rebalance. Formula: Reject unstable exposure
- Sector Normalization
- Sector normalization reduces the chance that a factor score is just a disguised industry or market-cap bet. Formula: Rank within comparable groups
- a security is cheap relative to peers while its price trend remains positive
- a security is cheap relative to peers while its price trend remains positive turns factor ranking into an investable position only after the score clears the tested inclusion rule. Formula: Score crosses inclusion rule
- Weighting Rule
- The weighting rule converts selected securities into portfolio exposure while limiting concentration in any single name or factor. Formula: Score, equal, or risk weight
- Rebalance Calendar
- A fixed rebalance calendar prevents hindsight entries and makes turnover, data lag, and execution cost assumptions testable. Formula: Monthly or quarterly refresh
- Rank Decay Exit
- The rank decay exit removes or reduces securities when value score deteriorates, momentum breaks, or the combined rank leaves the target bucket, keeping the portfolio aligned with current factor evidence. Formula: value score deteriorates, momentum breaks, or the combined rank leaves the target bucket
- Turnover Budget
- A turnover budget stops small score changes from creating trades whose costs are larger than their expected factor benefit. Formula: Trade only if benefit > cost
- Exposure Drift
- Exposure drift rules force a rebalance when market movement changes beta, sector, or factor exposures beyond the tested limits. Formula: Rebalance when constraints break
- sector caps, factor-balance bands, and momentum crash de-risking
- sector caps, factor-balance bands, and momentum crash de-risking defines the explicit controls that stop a factor portfolio from becoming an unintended one-way exposure. Formula: Factor and portfolio limits
- Beta Control
- Beta control separates factor selection skill from simple market direction and keeps the strategy comparable across regimes. Formula: Portfolio beta within band
- Crowding Review
- Crowding review asks whether many investors may be holding the same factor portfolio, increasing drawdown risk during forced exits. Formula: Reduce shared crowded exposure
