Core sizing rules
- Target entry size so a full exit over 3-5 days is <20 percent of expected volume.
- Use limit orders; avoid crossing wide spreads in one clip.
- In baskets, cap any single illiquid name to keep aggregate liquidity risk manageable.
Spread and impact math
- Expected cost per share ≈ half-spread + impact.
- Impact rough guide: 0.1-0.3 percent per 1 percent of daily volume you trade, higher in stressed markets.
- Bake this into your required discount to NCAV/NTAV before entering.
Exit planning
- Pre-plan exit path: time-sliced orders, opportunistic sells on volume spikes, and a catalyst-based deadline.
- Avoid being forced out by margin or risk rules; size so you can wait for liquidity days.
Risk mitigants
- Prefer names with insider ownership but reasonable float to trade.
- Avoid clustered correlations (all small cyclicals).
- Re-estimate volume after catalysts or filings; liquidity can shrink fast.
