Account balance

How to display the total account market value during an ongoing order settlement cycle?

Total Account Market Value = Balance + Value (all settled fund units × last closing price) + Sum of pending subscription cash amounts

Definitions:

  • Balance — Snapshot of settled cash on the account.
  • Value — Total market value of settled fund positions = Σ(units held × Last closing price per fund).
  • Pending subscription cash amounts — Cash you've sent/allocated that hasn't been converted into fund units yet.
  • Pending redemption units — Units instructed to redeem but not yet settled; value them at Last closing price if they're not already included in Value.
  • Last closing price — Most recent published NAV per fund (last known close).

Example:

  • Balance: 25,000 SEK
  • Value of settled positions: 80,000 SEK
  • Pending subscription orders (amount): 10,000 SEK
  • Pending redemptions orders: 1,000 units of Fund A
  • Last close Fund A: 100

Total Account Market Value = 25,000 + 80,000 + 10,000 + (1,000 x 100) = 215,000

Performance

What model does Fondo use for portfolio performance calculations?

Two main approaches are typically used for presenting performance over time for a portfolio of fund holdings - Time-Weighted Return (TWR) and Money-Weighted Return (MWR).

Time-Weighted Return (TWR)

Performance of the investments themselves, independent of the timing/size of client deposits and withdrawals (matches how fund factsheets report).

How it's computed (conceptually):

  1. Split the timeline at every external cash flow.
  2. Compute a sub-period return for each flow-free segment.
  3. Chain (geometrically multiply) the sub-period returns.

Sub-period i:

rᵢ = (UBᵢ − CFᵢ) / IBᵢ − 1

Chain across n sub-periods:

TWR = ∏(1 + rᵢ) − 1
for i = 1 to n

Pros/Cons & usage:

  • ✅ Neutralizes client cash flows → fair view of manager/strategy skill.
  • ✅ Standard for public performance comparisons.
  • ⚠️ Not the investor's personal experience if they time cash flows poorly/well.

Money-Weighted Return (MWR)

The investor's actual, cash-flow-timing-aware return on capital. Formally the internal rate of return (IRR) of all dated cash flows:

Σ CFₜ / (1 + r)^(t/T) = 0
  • CFₜ are dated cash flows (deposits positive, withdrawals negative; final value treated as an outflow).
  • T normalizes time units (e.g., days per year).

Practical approximation — Modified Dietz:

r_MD = (EV − BV − Σ CFₖ) / (BV + Σ wₖ × CFₖ)
  • BV = beginning value, EV = ending value
  • CFₖ = each external cash flow during the period
  • wₖ = time weight for each flow (fraction of the period remaining after the flow)

Pros/Cons & usage:

  • ✅ Reflects the client's real, dollar-weighted outcome.
  • ✅ Useful for personal statements, planning, and advisor reviews.
  • ⚠️ Not ideal for comparing manager skill (timing dominates).
  • ⚠️ IRR can be non-unique or fail with certain cash-flow patterns; Modified Dietz is a robust proxy.

In the Fondo context

  • Displayed portfolio performance (%) — TWR: We present time-weighted return, consistent with fund factsheets and isolated from external cash flows.
  • Client-specific performance — MWR/IRR is not supported. For questions like "How did my money grow given when I invested?" you'd use a money-weighted method rather than TWR.

Note: Beyond deposits and withdrawals, other events (e.g., corporate actions, distributions, and fees) can affect performance and must be taken into account to ensure adequate TWR calculations.
