Stock Portfolio Research

Reconstruct portfolio weights, cash flows and simulated accounts with transparent rebalance and evaluation rules.

22 guides

• Check whether candidate stock trading rules can be executed

  Map a manually supplied candidate rule to observable inputs, supported decisions and next-session execution, while preserving unknown fields and approval scope.

• Calendar or threshold rebalancing for a stock portfolio?

  Compare scheduled and weight-deviation rebalancing with shared capital and execution, retaining blocked triggers, drift duration, turnover and costs.

• Compare simulated stock opportunities with actual-trade records

  Match synthetic execution records to explicit opportunity references, verify identity and timing, and separate quantity deviations from coverage gaps and ambiguity.

• Prepare trading records before deriving a stock strategy

  Pair auditable stock round trips, reconcile net profit and currencies, and distinguish a five-winning-round eligibility gate from evidence that a strategy works.

• Equal weight or inverse volatility for a fixed stock basket?

  Generate weights from lagged stock histories, execute self-financing rebalances with costs, and compare drift and turnover under shared eligibility rules.

• Test a winner-derived stock rule on future opportunities

  Freeze the observation window and decision thresholds, retain every planned future opportunity and loss, and distinguish negative evidence from insufficient coverage.

• Report simulated stock portfolios separately by currency

  Gate USD, HKD and CNY observations separately, preserve unfunded waiting states, and keep optional FX display distinct from a mixed-currency trading account.

• Merge overlapping stock strategies into one funded portfolio

  Combine long-only sleeve targets under one currency and capital budget, merge security identities, and retain cap adjustments and cash before executing portfolio trades.

• Attribute multi-period stock portfolio excess returns

  Reconcile security-level active contributions, fees and compounding interaction, then apply an explicit linking identity to reproduce total benchmark-relative return.

• Recover a simulated stock account without duplicate trades

  Replay confirmed events from a hashed checkpoint, validate duplicate payloads and sequence continuity, and stop at missing quotes or unknown rule versions.

• Start a stock simulation from a frozen holdings snapshot

  Initialize an independent synthetic branch from confirmed stock quantities and separate cash, preserve excluded holdings, and prevent later account changes from syncing in.

• Track cash and positions in a simulated stock account

  Apply confirmed synthetic fills to a separate cash and share ledger, reconcile each transition and valuation, and retain unfilled or unfunded events unchanged.

• Check which stock trades a simulation universe can observe

  Match requested securities against a versioned basket and effective intervals, separating missing quotes and excluded stocks from genuine rule decisions.

• Diagnose active risk when stocks lag a benchmark

  Align portfolio and benchmark returns, compute realized tracking error, and trace large active losses to beginning weights without inferring safety from correlation.

• Rebalance stock holdings with new cash contributions

  Compare buying underweights with new cash against a full rebalance, preserving contribution timing, cash feasibility, selling costs and remaining drift.

• Diagnose infeasible stock portfolio constraints

  Separate mathematical infeasibility from missing inputs and unavailable solvers, then revalidate every proposed or fallback allocation before accepting it.

• Reduce stock replacement churn with a rank buffer

  Apply fixed entry and exit ranks to the same stock rankings, track retained members and actual trades, and keep vacancies or blocked exits explicit.

• Track sector weight drift between stock rebalances

  Value the entire holding interval, identify first and sustained sector breaches, preserve unknown classifications, and distinguish monitoring from automatic enforcement.

• Reconcile time-weighted and money-weighted stock returns

  Rebuild TWR and dated-cash-flow MWR from one stock portfolio ledger, reconcile contribution timing, and report unavailable or multiple IRR solutions honestly.

• Measure stock weight drift from whole-share and lot constraints

  Translate periodic targets into verified trading units, then track planned and actual quantities, blocked sells, cash limits and residual cash without renormalizing it away.

• Find why a stock simulation signal produced no virtual trade

  Trace each synthetic signal through coverage, valuation, position, cash and fill confirmation, retaining one explicit outcome without changing unfilled holdings.

• Update stock trading rules in separate simulation branches

  Freeze the existing rule and account state, register a separate candidate version, and compare continuing and common-start observations without rewriting history.
