Portfolio Risk Management Guide

Equity Risk Management: Position Sizing, Drawdowns and Hedges

Equity risk management sets limits on exposure, evaluates possible losses and defines when to review positions. It cannot guarantee a loss ceiling: gaps, correlations, financing costs and hedge terms can make realized losses differ from a plan.

Separate trade risk, portfolio exposure and liquidity

A stop-based trade budget is not the same as a portfolio loss limit. Multiple positions can fall together, and the price available when exiting may be worse than the planned stop.

LevelQuestion to answerPractical constraint
TradeHow many shares fit the planned entry-to-stop distance?Include spread, fees and gap risk; a stop trigger does not guarantee a fill price.
PortfolioWhich holdings share a sector, currency or economic driver?Review concentration and fund overlap; correlations can change during stress.
LiquidityCould the position be reduced when cash is needed?Consider trading halts, market depth, settlement and margin requirements.

A position-size example with explicit assumptions

Assume a $50,000 account, a chosen 1% planned risk budget, a $100 entry and a $95 stop. The budget is $500 and the planned per-share price loss is $5, so $500 / $5 = 100 shares before costs. That is $10,000 of notional exposure, or 20% of account equity; an additional concentration cap could require fewer shares.

  • If the first available exit is $90 after a gap, 100 shares lose $1,000 before costs—2% of the account. The planned 1% is not a guaranteed maximum.
  • ATR-based stop distances can inform a sizing calculation. Beta measures sensitivity to a benchmark and is not interchangeable with ATR or a per-share loss amount.
  • A drawdown review threshold can prompt reassessment or reduce exposure. It does not ensure execution at the threshold and can cause repeated exits and reentries.

Compare hedge terms before relying on protection

A hedge changes the payoff and introduces costs, timing and operational constraints. Evaluate the exact instrument and contract terms rather than assuming a fixed level of protection.

  • A protective put gives the holder a right to sell the covered underlying at its strike during the relevant contract term. Premiums, contract size, expiry and exercise arrangements matter. An index put can leave basis risk against a different stock portfolio.
  • A collar combines owned shares, a long put and a short call on that underlying, normally with matching expirations. Call premium can offset some or all of the put cost, but caps upside and creates assignment risk. Standard U.S. equity options usually cover 100 shares; adjusted contracts can differ.
  • Buffer ETFs seek specified outcomes over a defined period, usually with capped upside. Buying after the period starts or selling before it ends can change the effective buffer. Fees reduce results, losses beyond the applicable buffer remain possible, and the outcome is not guaranteed. Check the fund prospectus.

Risk metrics describe a model or observation window

Choose a consistent return frequency, currency and observation period. No universal Sharpe, Sortino, beta or drawdown cutoff makes an equity portfolio safe.

MeasureDefinitionWhat it does not establish
Maximum drawdownLargest percentage decline from a preceding equity peak in the measured series.A historical maximum does not cap future losses; cash flows and valuation frequency affect measurement.
Sharpe ratioMean excess return divided by the standard deviation of excess returns at a consistent frequency.It requires a stated risk-free benchmark and annualization assumptions; it is unstable with little or nonrepresentative data.
Sortino ratioReturn above a stated target divided by downside deviation relative to that target.Results depend on the target and downside-deviation convention.
BetaCovariance with benchmark returns divided by the benchmark return variance.It measures historical linear sensitivity, not total loss risk or a stop distance.
Value at Risk (VaR)A loss-distribution quantile at a stated horizon and confidence level.A 95% VaR allows losses beyond the threshold in the model; it does not measure their severity or a worst-case loss.

What Pineify can support

Pineify Finance Agent can retrieve available financial data to support company research. Inspect the returned sources, dates and missing values. This guide does not provide a connected portfolio monitor, an individualized risk audit or automatic order execution.

  • Pine Script can express entry, exit and sizing rules for TradingView strategy simulations. Strategy equity refers to the simulated account; it is not a live brokerage balance. Costs, fills, dates and data coverage still require configuration.
  • Pineify Strategy Optimizer compares parameter combinations through its TradingView browser extension. It requires Advanced or higher access. Parameter trials are not automatically separate market-crash scenarios or an out-of-sample portfolio stress test.
  • Live orders need a separately configured and tested alert, integration and broker workflow. Research, generated code and a favorable backtest do not ensure that risk rules will execute as intended.
Where Pineify fits

AI Finance Agent

Research available company financial statements and ratios, then verify the underlying sources and dates. This is a research workflow, not a live brokerage risk controller.

Also useful: Strategy Optimizer. Compare TradingView strategy parameter combinations with the browser extension; Advanced or higher access is required. Review costs and out-of-sample performance separately.
