Key Findings from Sveriges Riksbank Working Paper Series 408
This study investigates the performance of cryptocurrency funds, focusing on their ability to generate alpha relative to passive benchmarks and traditional risk factors. Below is an organized summary of the core content:
1. Introduction
- Cryptocurrency markets have grown exponentially, attracting institutional investors through specialized funds.
- Objective: Assess whether active management in cryptocurrency funds adds value beyond passive investments.
Unique Context:
- Highly fragmented, decentralized markets with potential diversification benefits.
- Low competition among crypto funds (top 1% manage >50% of assets).
- Lax regulatory oversight compared to traditional mutual funds.
2. Data & Methodology
Fund Sample:
- 250 actively managed funds (2015–2021), including hedge funds, tokenized funds, and fund-of-funds.
- Strategies: Long-short, long-term, market neutral, multi-strategy, and opportunistic.
Benchmarks & Risk Factors:
- Passive Benchmarks: Bitcoin (BTC), Ethereum (ETH), equal-weight top 100 cryptos, Coinbase index.
- Risk Factors: Momentum, reversal, liquidity, volatility, and market (value-weighted top 100 cryptos).
Method:
- Panel regressions with strategy-clustered standard errors.
- Bootstrap analysis to distinguish skill from luck.
3. Key Results
Aggregate Fund Performance
| Metric | Benchmark-Adjusted Alpha | Risk-Adjusted Alpha |
|----------------------|--------------------------|---------------------|
| Average Fund | +3.40% (t = 3.57) | +2.59% (t = 3.49) |
| By Strategy: | |
| Long-short | +3.59%* | +1.93% (t = 1.88) |
| Market neutral | Insignificant | Insignificant |
👉 Passive benchmarks explain 50–60% of fund returns, but alphas remain significant after adjustments.
Individual Fund Performance
Cross-sectional analysis reveals:
- Top 10% of funds generate monthly alphas >10%.
- Right-tail performance unlikely due to luck (bootstrap p < 0.05).
- Heterogeneity: Long-short and long-term strategies dominate outperformance.
4. Robustness Checks
- Sub-periods: Post-2018 ICO bubble shows weaker but still positive alphas.
Alternative Methods:
- Panel vs. time-series regressions → Panel estimates are more conservative.
- Block bootstrapping confirms skill persists after accounting for autocorrelation.
5. Implications
- Active management in crypto funds can add value, though performance varies by strategy.
- Statistical significance weakens when accounting for within-strategy correlation.
- Supports Berk & Green (2004): Skilled managers cover costs but face diminishing returns with scale.
FAQs
Q: Do cryptocurrency funds outperform Bitcoin?
A: On average, yes—top funds generate significant alphas after adjusting for BTC’s returns.
Q: Which strategies perform best?
A: Long-short and long-term strategies show persistent outperformance.
Q: Is regulatory oversight a concern?
A: Yes—8% of funds are SEC-registered, raising questions about risk management in unregulated funds.

Final Note: While crypto funds exhibit skill, investors should evaluate strategy-specific risks and correlations.
