Oak Special Fund vs Mansa‑X Special Fund: Fees, Tax, and Superior Strategy
⚙️ Understanding the Fee Structure Before Net Return Examples
Investors must grasp the fee mechanics before comparing performance:
- Management Fees
Mansa‑X charges 5% per annum, deducted daily. OAK charges 6% per annum, also daily. These fees compensate experienced teams who actively manage multi‑asset portfolios. - Performance Fees (“carried interest”)
Both managers take 10% of returns above a set hurdle:- Mansa‑X: Above 25% gross return (KES fund) or 15% (USD fund).
- OAK: Above a 20% per annum target.
These motivate managers to exceed benchmarks and align interests tightly with investors. If gross performance doesn’t beat the hurdle, no performance fee is charged.
- Fees help pay for complex trading systems, risk controls, and continuous research—making these funds more capable and dynamic compared to passive vehicles.
💰 Real Fee Impact Example
Let’s say you invest KES 1,000,000 in each fund for one year.
Mansa‑X Example
- Gross return (before fees): 20% → KES 1,200,000
- Mgmt fee: 5% → -KES 50,000 = KES 1,150,000
- Performance fee: 10% on (20–25% hurdle = 0) → nil (you didn’t beat 25%)
- Net you get: KES 1,150,000 → +15% return
If the fund hit 30% gross:
- You’d exceed hurdle by 5% → KES 50,000.
- 10% performance fee → -KES 5,000.
- Net return = 30% – 5% (mgmt) – 0.5% (perf) = +24.5%
OAK Fund Example
- Gross: 25% → KES 1,250,000
- Mgmt fee: 6% → -KES 60,000 = 1,190,000
- Performance fee: 10% on (25–20% target = 5%) = -KES 5,000
- Net you get: KES 1,185,000 → +18.5% return
Key Takeaway: Gross returns must exceed the fee threshold to enjoy full benefits.
📤 Tax Treatment and Withholding Tax on Returns
- Withholding Tax on Distributions
Returns distributed—such as interest, dividends, or gains—are typically subject to 15% withholding tax at source in Kenya. This is credited against your annual tax liability, not an extra tax. That tax is deducted before you receive payouts. - Capital Gains vs Business Income
Under Kenyan Income Tax law, gains may be treated as ordinary income—especially with active trading funds. These are subject to regular income taxation, not a separate capital gains window
🔍 Enriched Fee & Tax Examples (Without Net Return Table)
Imagine two scenarios:
- Mansa‑X with 20% gross return
- Management fee: 5% → leaves 15%
- No performance fee (didn’t exceed 25% hurdle)
- Then 15% withholding tax on distributions → net payout ~12.75%
- OAK with 25% gross return
- Mgmt fee: 6% → leaves 19%
- Performance fee: 10% on excess ≈1% (5% over the 20% target)
- After performance fee: 18%
- Tax withheld (15% of distributions) → net ~15.3%
Note: exact after-tax depends on fund payout structure and whether gains are retained or distributed.

💡 Why These Funds Outperform Forex Trading
- Diversification Beyond Currency
Unlike forex trading, both of these special funds invest across equities, bonds, ETFs, commodities, and FX—reducing risk vs single-asset trading. - Professional Risk Management
These special funds use hedging, tactical long/short positions and portfolio rebalancing. Forex traders often lack such tools or expertise. - Regulated & Transparent
Both are also licensed by the CMA, use custodians, follow audited valuations, and must comply with strict governance standards. Forex brokers may operate with limited oversight. - Passive Investment without Stress
You’re free from chart-watching and emotional trading. Fund managers handle trades, so your money can compound quietly. - Downside Control via Leverage Management
Long/short strategies allow managers to limit drawdowns—unlike pure forex trading, where loss potential is higher and typically unhedged.
