Trading Rebalancing · Lesson 01
Trade execution fundamentals
Trading is where our investment decisions become real. A well-designed portfolio, a perfect allocation, a brilliant tax strategy — all of it means nothing if the trades are executed incorrectly. This lesson covers the fundamentals of how we execute trades at Minerva.
The three-step trade process
Step 1: Proposal (Eclipse iRebal)
Eclipse iRebal compares each client's current allocation to their target model and proposes the trades needed to bring them into balance. The system considers:
- Target allocation bands (typically ±5%)
- Minimum trade size thresholds (we don't rebalance for trivial drift)
- Tax-lot selection in taxable accounts
- Cash reserve requirements (always maintain the specified cash buffer)
- Wash-sale rule compliance (no repurchase of substantially identical securities within 30 days of a loss harvest)
The proposals are generated in batch during quarterly rebalancing or ad-hoc for individual client events (new funding, distribution, model change).
Step 2: Review (Advisor approval)
Every trade proposal must be reviewed and approved by the responsible advisor before execution. The advisor checks:
- Does the trade make sense given the client's current situation?
- Are there any tax considerations iRebal might not be aware of? (expected income spike, pending charitable donation, estimated tax payment timing)
- Are there any wash-sale rule issues from recent tax-loss harvesting?
- Is the client expecting a large cash flow that would make rebalancing premature?
The advisor signs off in the trade management system. Trades without sign-off cannot proceed.
Step 3: Execution (Operations)
Once approved, operations submits the trades to the custodian. For our standard index fund trades:
- Market orders are used for highly liquid ETFs (S&P 500, Total Market, etc.) during normal market hours
- Limit orders are used for less liquid ETFs or during volatile markets
- Mutual fund orders are placed at NAV (net asset value) and execute at market close
- All orders are placed between 10:00 AM and 3:30 PM ET to avoid the volatility of market open and close
Tax-lot selection
In taxable accounts, which specific shares we sell matters for taxes. Minerva uses specific identification — selecting individual tax lots to sell based on the most tax-advantageous outcome.
The hierarchy:
- Loss lots first — Sell shares at a loss to generate tax-loss harvesting benefits (check wash-sale rule compliance first)
- Long-term gain lots — If we must sell at a gain, sell lots held over one year (taxed at the lower 15–20% capital gains rate)
- Highest-cost lots — Among long-term lots, sell the highest-cost-basis lots first to minimize the gain
- Avoid short-term gains — Lots held under one year are taxed at ordinary income rates (up to 37%). We avoid selling these unless absolutely necessary.
Eclipse iRebal automates most of this, but the advisor must verify tax-lot selection during the review step, especially for large rebalancing trades.
The double-check protocol
Trade errors are among the most serious operational risks at an RIA. Common errors include:
- Wrong account (trading in spouse's IRA instead of the client's)
- Wrong fund (buying international when U.S. was intended)
- Wrong quantity (extra or missing zero)
- Wrong direction (buying when the proposal called for selling)
Our protocol: before submitting any trade batch, a second team member independently verifies the trade details against the approved proposal. This is not optional, and "I was in a hurry" is not an acceptable reason to skip it.
If a trade error occurs:
- Stop. Do not attempt to fix it without notifying a supervisor.
- Document the error immediately in the trade error log.
- The supervisor determines the corrective action (reversal trade, client notification, compliance reporting).
- The client is never financially harmed by our error — we absorb the cost.
Trade documentation and reconciliation
Every executed trade must be:
- Recorded in the trade blotter with date, time, account, fund, quantity, price, and approver
- Reconciled against the custodian's trade confirmation within 24 hours
- Flagged immediately if any detail doesn't match
The trade blotter is a compliance requirement and an audit trail. Incomplete records are a regulatory finding.
Key takeaways
- Every trade follows three steps: proposal (iRebal), review (advisor), execution (operations). No step is skippable.
- Tax-lot selection uses specific identification: losses first, then long-term gains, then highest-cost basis. Avoid short-term gains.
- The double-check protocol requires a second team member to verify every trade batch before submission.
- Trade errors are never absorbed by the client — Minerva takes the loss.
- All trades must be documented in the trade blotter and reconciled with custodian confirmations within 24 hours.
Glossary
- Eclipse iRebal — Minerva's automated rebalancing tool that generates trade proposals based on target allocations and tax considerations.
- Specific identification — A tax-lot selection method where the investor (or advisor) chooses which specific shares to sell, rather than defaulting to FIFO or average cost.
- FIFO (First In, First Out) — A default tax-lot method that sells the oldest shares first. Minerva does not use this method; we use specific identification.
- Trade blotter — The log of all executed trades, including date, account, fund, quantity, price, and approver. Required for compliance and audit purposes.
- Wash-sale rule — IRS rule prohibiting a tax loss deduction if you repurchase a substantially identical security within 30 days.
- NAV (Net Asset Value) — The per-share value at which mutual fund orders are executed, calculated at market close each day.
- Double-check protocol — Minerva's requirement that a second team member independently verify trade details before submission to the custodian.

- 1What are the three steps of Minerva's trade execution process, in order?
- AExecution, review, documentation
- BProposal (iRebal), review (advisor), execution (operations)
- CClient request, advisor approval, custodian submission
- DResearch, selection, purchase
Reveal answer ↓
Answer: B
Every trade follows three steps: Eclipse iRebal generates proposals, the advisor reviews and approves them, and operations submits them to the custodian. No step can be skipped.
- 2In taxable accounts, which tax lots should be sold first?
- AThe oldest lots (FIFO)
- BThe newest lots (LIFO)
- CLots at a loss (for tax-loss harvesting), then long-term gain lots with the highest cost basis
- DWhatever lots iRebal selects automatically, without advisor review
Reveal answer ↓
Answer: C
Minerva uses specific identification: sell loss lots first for tax-loss harvesting, then long-term gain lots (lower tax rate), prioritizing highest-cost-basis lots to minimize gains. Advisors must verify iRebal's selections.
- 3What happens if a trade error occurs?
- AThe client absorbs the cost of the error
- BThe error is quietly fixed without documentation
- CStop, notify a supervisor, document the error, and Minerva absorbs any client cost
- DThe trade is ignored and corrected at the next quarterly rebalance
Reveal answer ↓
Answer: C
Trade errors must be immediately reported to a supervisor and documented in the error log. The client is never financially harmed — Minerva absorbs the cost of any trade error.
