The total value, daily change, or distribution chart displayed on the portfolio screen may seem sufficient at first glance. However, to interpret portfolio data correctly, you need to know the date, currency, cost method, and data source on which the figures are based. This data serves as input for decisions that help you understand your financial situation; it is not, on its own, a buy or sell recommendation or a guarantee of future returns.
Check the context before interpreting portfolio data
The same portfolio may appear differently on different screens. This is due to the price update time, currency conversion, whether transaction costs are included, or the cost calculation method. First, answer the following questions:
- When were the values last updated?
- In which base currency is the total displayed?
- At what exchange rate were the different currencies converted?
- Have commissions, taxes, and other costs been included in the calculation?
- Are physical assets priced automatically or based on manual estimates?
Comparing two periods or two platforms without this information may yield inaccurate results. In particular, the last price seen outside of market hours may not be the same as the current tradable price. Data delays and different sources can create minor or significant discrepancies.
What do key portfolio metrics indicate?
Total portfolio value
This is the sum of the values of the assets in the portfolio, converted to the base currency, at a specific point in time. This figure does not guarantee that the assets can be converted to cash simultaneously at the displayed prices. Liquidity, bid-ask spread, market depth, trading hours, and costs may affect the actual outcome.
Cost basis
This represents the total amount recorded for the acquisition of assets. If purchases were made on multiple dates, the average cost method may be used. However, calculation methods may vary across platforms. If historical cost data is missing for transferred assets, the displayed result will be inaccurate. It is important to verify cost data using transaction records.
Unrealized Change
This is the difference between the current estimated value and the recorded cost. Since the asset has not yet been sold, the result is unrealized. Prices may fluctuate; furthermore, commissions, taxes, and exchange rate effects may not be fully reflected on the screen. Therefore, the term “unrealized gain or loss” does not represent the final cash outcome.
Realized Result
Shown as the result arising from completed transactions. To interpret this correctly, check which cost method was used and whether expenses were included. If transactions such as cash withdrawals, dividends, or coupons are recorded separately, a discrepancy may arise between the total performance screen and the transaction summary.
Daily Change
This typically shows the difference between the current price and the last market close or the previous reference price. The term “Today” may correspond to different time periods across various markets. Daily movement alone does not explain long-term performance or risk level.
How to Interpret the Return Rate?
Simple return measures the change in value relative to the initial amount. However, if funds were added or withdrawn during the period, this calculation can conflate investment performance with cash flow. In such cases, different measurement methods—such as time-weighted and money-weighted returns—answer different questions.
- Simple rate of change: Summarizes the difference between the beginning and ending values; it is limited in accounting for interim cash flows.
- Time-weighted return: Aims to compare performance over a period by reducing the impact of cash inflows and outflows.
- Money-weighted return: Takes into account the timing and magnitude of cash flows; presents the result from a different perspective.
Do not compare with other portfolios or indices without knowing which rate is being shown. Also, nominal change is not the same as a change in purchasing power. Inflation and exchange rate movements may require you to evaluate the result from a different perspective.
What does the portfolio allocation chart show?
The allocation chart shows the share of each asset or asset group within the total value. A large slice indicates that the portfolio may be more sensitive to price movements in that asset class. However, simply looking at category names is not enough. Assets within the same category may have different currency, sector, maturity, or liquidity characteristics.
A change in the allocation does not always mean you’ve made a new trade. When the price of one asset changes more rapidly than others, its weight may automatically increase or decrease. Therefore, you need to interpret additions and withdrawals separately from price effects. Allocation data describes the current situation; it does not tell you which allocation is right for you.
What do risk metrics mean?
Volatility
It attempts to measure how much a price or return series fluctuates. High historical volatility does not mean there will definitely be a loss in the future; low historical volatility is no guarantee either. The period and data frequency used can significantly alter the result.
Maximum Drawdown
It indicates the largest decline from a peak to a trough during the period under review. It depends on the selected start and end dates. The largest drawdown observed in the past is not the upper limit of potential future losses.
Correlation
It indicates the extent to which two data series have moved in tandem in the past. Correlation can change over time and does not imply causation. Assets that appear different may move in a similar direction during periods of stress. This metric should not be interpreted on its own as evidence of diversification.
How do you isolate the currency effect?
The change in the value of a foreign-currency-denominated asset in your base currency can consist of two components: the asset’s own price movement and the movement in the exchange rate. Even if the asset’s price remains unchanged in its own currency, its total value may appear different due to the exchange rate. Conversely, an increase in the asset’s price may be partially or completely offset by exchange rate movements.
When making comparisons, examining the figures in both the local currency and the base currency helps you understand the source of the change. Check whether the exchange rate used is the buy rate, sell rate, mid-market rate, or another reference rate. The conversion amount shown may not be the same as the amount you would receive in an actual transaction.
How should physical asset data be interpreted?
Physical assets such as homes, vehicles, works of art, or collectibles may not have a consistent, single market price. On biriqim, these entries are manually entered by the user as estimated values. This amount is not an appraisal, a final sale price, or a real-time market price. If the valuation date is old, the total portfolio view may also become outdated.
It is helpful to include the date, source, and a brief note on the valuation method alongside the estimated value. Similar listings may only show asking prices; the actual sale price may differ. Additionally, the sales period, expenses, and taxes may affect the net value. A high proportion of physical assets does not necessarily mean the entire portfolio can be easily converted to cash.
Checklist for a Fair Comparison
- Use the same date range and the same base currency.
- Check deposits, withdrawals, and transfers separately.
- Correct any missing or duplicate entries in the cost data.
- Verify the price update time and data source.
- Separate nominal changes from exchange rate and purchasing power effects.
- Review the manual estimation dates for physical assets.
- Compare multiple periods rather than just a single day’s activity.
biriqim makes it easy to track and analyze different asset records in a single view; it is not a bank, brokerage firm, or money transfer app. No buying or selling takes place through the platform. The on-screen analyses help you understand your own records; they do not recommend any transactions or generate automated decisions.
Frequently Asked Questions
Why might the portfolio value appear different in the two apps?
The price source, update time, currency conversion, cost method, and included fees may differ. Check the calculation notes for each screen before comparing.
Does a high rate of return mean it will continue in the future?
No. Past performance does not guarantee future results. The time period selected, cash flows, risk, and costs can affect the displayed rate.
Does the portfolio allocation provide an investment recommendation?
No. The allocation shows the current proportions of your holdings. Suitability depends on numerous factors, such as personal goals, risk tolerance, time horizon, and obligations.
