Market data
How our prices work.
No figure on ValueBase is a real-time quote. Some run a quarter of an hour behind, some show the last completed session, and some come from a periodic snapshot. This page says which is which, so you always know what you are looking at.
The four kinds of price on the site
Delayed quotes
At least 15 minutes behind the marketThe price, day change and market value of your holdings, the index tiles and heatmap on the home page, and the day's biggest movers. Currency and crypto rates are the exception and update continuously.
Closing prices
The last completed trading sessionEvery chart, your portfolio's value over time, the benchmark it is measured against, and the yearly returns breakdown. Some smaller venues have no intraday feed at all and always show a close.
Snapshot figures
May be a full trading day behindThe screener and its statistics, the market value the DCF calculator starts from, the price-based metrics on a company page, and the 52-week-low panel on the superinvestors page.
Prices from filings
As at the transaction date in the filingInsider transactions, superinvestor 13F holdings, and the average price a company paid in a buyback. These describe a past transaction and were never a quote.
What this means in practice
Not for trading
ValueBase is built for research and for tracking what you already own over years, not for deciding what to do in the next few minutes. Place an order on the strength of a figure here and the market will have moved. Use your broker's own quote for anything time-sensitive.
Your portfolio value is an estimate
A portfolio total is the sum of delayed prices, converted at delayed exchange rates. It is close enough to tell you how a position is doing and wrong enough that it will not match your broker to the penny. Where a price has stopped arriving altogether we mark the holding rather than quietly carrying the old number forward.
Screens and ratios lag further
Anything built on a snapshot, including every price-based ratio in the screener, can be a full trading day behind. Sorting by the day's change will not give you today's movers. For a value investor holding for years this rarely matters, but it is worth knowing before you read a number as current.
Filing prices are history
An insider's purchase price or a superinvestor's reported holding comes from a regulatory filing and describes a transaction that has already happened, often months earlier. It was never a quote and should not be compared with today's price without allowing for the gap.
If a number looks wrong
Data disagreements are the most welcome kind of bug report we get. If a price, a market capitalisation or a ratio looks wrong, tell us which company and what you expected, and we will trace it back to where it came from.
