Understanding the Cash Balance: Why Does the Strategy Sometimes Show Cash During Risk-ON?
An operational guide explaining why our target equity allocation is always 100% in active markets, why smaller accounts display an unallocated cash residue when trading whole shares, and how fractional shares enable complete capital deployment.
Core Policy: Whenever the macro environment is in Risk-ON, the Evergreen Hydra Strategy does NOT deliberately hold cash reserves. The target allocation is 100% invested across our four active portfolio slots. Any uninvested balance displayed in trade execution instructions is solely the mathematical residue of whole-share integer rounding.
In institutional finance, algorithmic backtests and broker trade tickets assume standard whole-share purchases to avoid execution incompatibilities across traditional custodians.
When market leaders trade at high share prices (often between $300 and $600+ per share), purchasing discrete whole units on accounts with smaller capital allocations creates natural "lumpiness":
| Active Slot Holding | Share Price | Whole Shares Purchased | Invested Equity | Next Share Cost |
|---|---|---|---|---|
| Slot 1: VLO | $456.37 | 5 shs | $2,281.85 | +$456.37 |
| Slot 2: AAPL | $341.27 | 5 shs | $1,706.35 | +$341.27 |
| Slot 3: HUM | $420.03 | 4 shs | $1,680.12 | +$420.03 |
| Slot 4: DELL | $572.34 | 6 shs | $3,434.04 | +$572.34 |
| Portfolio Totals: | 20 shs | $9,102.36 (91.0%) | Unallocated Cash: $897.64 to $1,046.04 (9.0% to 10.4%) | |
On an account allocated with $10,000, each slot targets approximately 25% of capital ($2,500). Notice that attempting to purchase just one more share of any holding would require between $341.27 and $572.34. Buying an extra share across multiple slots would cause the total purchase cost to exceed available funds, triggering an unwanted margin debit.
Consequently, the execution engine conservatively stops at the highest whole share count that safely stays within account bounds, leaving the remainder in cash.
Because whole-share rounding is a fixed dollar constraint (the price of a single share), the percentage of unallocated cash residue rapidly diminishes as portfolio size increases:
| Account Allocation | Approximate Invested Equity % | Unallocated Cash Residue % | Execution Character |
|---|---|---|---|
| $10,000 | ~90.0% – 92.5% | ~7.5% – 10.0% | Noticeable whole-share integer friction |
| $50,000 | ~98.0% – 98.8% | ~1.2% – 2.0% | Minimal unallocated residue |
| $100,000 | ~99.2% – 99.6% | < 0.5% – 0.8% | Near-perfect full capital deployment |
| $500,000+ | ~99.8% – 99.9% | < 0.1% – 0.2% | Virtually zero cash drag |
How to Achieve 100.0% Equity Investment on Any Account Size
If your brokerage platform supports fractional share trading (such as Fidelity, Charles Schwab, Interactive Brokers, or Robinhood), you do not need to restrict yourself to whole integers:
- Place Dollar-Based Orders: Instead of entering orders by share quantity, simply allocate your target dollar amount per slot (e.g., $2,500.00 each into VLO, AAPL, HUM, and DELL).
- Exact Mathematical Weighting: Your broker will purchase precise fractional amounts (e.g., 5.48 shares of VLO, 7.33 shares of AAPL, 5.95 shares of HUM, and 4.37 shares of DELL).
- Zero Cash Drag: Your cash balance immediately drops to $0.00, achieving 100% active compounding exactly like the underlying quant model.
Based on integer rounding friction and fractional share capabilities, here are the practical capital requirements for deploying the Evergreen Hydra Strategy:
| Execution Pathway | Recommended Minimum | Cash Drag Impact | Strategy Replication Fidelity |
|---|---|---|---|
| Fractional Share Account Fidelity, Schwab, IBKR, Robinhood |
$500 – $1,000 | 0.0% | 100% Perfect Math Match |
| Whole Shares (Absolute Floor) Traditional brokers without fractional units |
$5,000 | ~15.0% – 20.0% | Acceptable (noticeable integer lumpiness) |
| Whole Shares (Recommended Practical Floor) Optimal balance for standard whole-share execution |
$25,000 | < 2.5% | High Fidelity (> 97.5% invested) |
| Whole Shares (Institutional Tier) Enterprise & High-Net-Worth execution |
$50,000 – $100,000+ | < 0.5% – 1.0% | Near-Flawless Replication (> 99.5% invested) |
Clear Investor Guidance: If starting with an allocation under $25,000, we strongly encourage executing through a broker that supports fractional share trading (such as Fidelity, Charles Schwab, or Interactive Brokers). This empowers you to allocate 100% of your dollars with zero rounding drag. If trading standard whole shares, a $25,000 minimum ensures rounding drag remains negligible (< 2.5%).
There is only one scenario where Evergreen Hydra intentionally holds substantial cash reserves:
- Risk-OFF Defensive Regime: When the broad market benchmark deteriorates below our long-term macro trend filter, the engine systematically liquidates all active equity holdings and commands a 100% Cash Safe Harbor.
- Capital Preservation in Bear Markets: In this defensive state, cash is not a byproduct of rounding—it is an active defense designed to insulate investor capital from secular bear crashes (as successfully demonstrated during 2000–2002 and 2008).
