How to judge your investment results

Separate the money you supplied from investment performance, then compare implementation and progress toward the goal.

A larger balance can contain a losing year.

Invented one-year example: no withdrawals or distributions paid outside the account. Values already reflect all investment costs. The €10,000 contribution arrives at the very end, after the investment result.

One euro scale for balances and changes. Changes join the before and after amounts; this is a reconciliation, not a price history.

  1. Opening value€50,000
  2. Investment change−€3,000

    ← Value lost during the year.

  3. Before the contribution€47,000
  4. External contribution+€10,000

    → Money added at the very end of the year.

  5. Closing value€57,000

    Includes the deposit; investments still lost 6%.

How did the investments do?
−6% here. Compare with a reference for the intended mix.

Is the goal funded?
€57,000 is available in this example. Compare it with the current expense and remaining time.

The deposit repairs the balance without reversing the investment loss. The reverse is possible: withdrawals can reduce a balance despite positive investment returns.

Reconcile the money before choosing a return measure

Balance growth is €7,000, or 14% of the opening €50,000. Remove the end deposit: €57,000 − €10,000 = €47,000; (€47,000 − €50,000) ÷ €50,000 = −6%. This simple return depends on the deposit arriving after the investment result.

Keep dated external flows for all included accounts. An internal transfer is no contribution or withdrawal for the combined portfolio.

Time-weighted return removes external-flow timing from the investment path. Money-weighted return includes flow size and timing. Apply the earlier cash-flow methods for several flows rather than using balance growth. Match currency and income treatment when comparing reports.

A mixed portfolio needs a reference for its mix.

Separate illustrative reference: starting weights 60% broad shares, 40% suitable bonds. Annual component returns 10% and 2%. No rebalancing, cash flows, costs or taxes; not a recommended allocation.

Blended reference

6.8%

Portfolio on the same basis

6%

0.8 percentage points behind

Choose the reference before the outcome. Define dates, currency, total-return treatment, costs and any rebalancing rule; broad asset names alone do not match markets and risks.

Calculate the blend; preserve the original comparison

60% × 10% + 40% × 2% = 6.8%; the gap to 6% is 0.8 percentage points. Comparing with shares alone gives four percentage points but omits the intended bonds.

Index results may omit investor costs, so the reference is not automatically achievable net. If strategy changes for a sound reason, date it and preserve the earlier comparison instead of selecting a more flattering history.

Explain a gap before replacing the holding.

Fees, uninvested cash, currency and allocation can explain differences. Align annualised versus cumulative figures and which expenses are included before subtracting costs again.

Concentration or leverage can raise returns without serving the same purpose. Assess losses and spending consequences; a favourable period cannot reveal every risk, and no fixed history proves skill or future results.

Use a stable period and cost scope

FINRA’s guidance includes fees, taxes, inflation and results across years. Check which costs the reported return already includes.

Consistent calendar years and the full period since the plan began provide a usable comparison, unlike a selected winning month.

A gain can coexist with a funding shortfall.

Compare available money, time and affordable contributions with the current cost in the spending currency. A positive nominal return establishes neither purchasing power nor sufficient funding.

Bring two separate findings to the review: any implementation gap against a matched reference, and any funding gap against the obligation. More capital from contributions is not evidence of better market performance.

Paused saving, a dearer goal and weak returns call for different responses. Correct costs, contributions or expectations as appropriate; adding risk to force an old projection back into place can worsen the shortfall.

Comparing reported results

Your portfolio lags a share index, but it deliberately holds bonds and cash as well. What should be checked first?

  • Whether the same fund also lagged the best-performing share market over those dates.
  • Whether the comparison reflects the portfolio's intended mix, currency, dates and costs.
  • Whether its share holdings lagged the index, excluding the bonds and cash from the assessment.
Show the explanation

Correct answer: Whether the comparison reflects the portfolio's intended mix, currency, dates and costs.

A mixed portfolio has a different exposure from a pure-share index. A gap can reflect that design rather than failed implementation. Use a relevant comparison and reconcile cash flows and costs before drawing a conclusion about the holdings.

An updated quote

Your available capital is now €22,000, while an updated quote puts the goal's cost at €25,000. What is still true even if the portfolio recently gained?

  • The gap should compare current capital with the goal's original cost, keeping later price changes separate.
  • The funding gap should use the original projection until the next scheduled annual review.
  • A €3,000 funding gap remains before other contributions and costs are considered.
Show the explanation

Correct answer: A €3,000 funding gap remains before other contributions and costs are considered.

Progress needs measuring against the current expense in its spending currency. €25,000 minus €22,000 leaves €3,000 to address. A favourable investment result and an unfunded goal can coexist; an updated cost is information for the plan, not a reason to keep an obsolete target.
