How do you read a fund's data block before you buy?
Everything the previous eleven lessons measured came from one place: a fund's own data record, the page the Terminal shows under a fund's fundamentals. Here is the reading order for it, line by line, with the traps marked.
The record, in reading order
Here is the S&P 500 fund, cut to the lines that decide whether a fund is what its name says:
Index tracked — the rulebook. If this does not name the index you thought you were buying, stop here.
Inception — how long the fund has existed. A fund launched last year has no track record through a bad market, whatever its index has done.
Net expense ratio — the fee. Shown here as a percentage; some fund pages give it as a fraction, where 0.00095 is 0.095% a year. Read a fraction as a percentage and every comparison you make is a hundred times off. This is the trap the fees lesson named.
Distribution yield — what the holdings paid out over the last year, as a percentage of the price.
Annual holdings turnover — how much of the portfolio was replaced in a year. 2% for a stable index tracker; ten to fifty times that for an active fund. A futures fund can read zero here while rolling every month, because a roll is not counted as turnover.
Total assets — size, in the fund's currency. Large is not better, but very small funds close, and a closure is a forced sale at a moment you did not choose.
Holdings count — on a data page this is often the length of the published holdings list, not the fund's constituent count: 50 here, for a fund holding about five hundred companies. Use the factsheet for the real number.
Domicile — the fund's legal address, which the domicile lesson turned into a withholding rate.
The second table: performance
The returns over one, three, five and ten years, annualised beyond one year; the volatility over one and three years in the same unit; and the Sharpe ratio, the return per unit of volatility that the was-it-worth-the-ride lesson explained. Both halves of the price tag, in one place. Funds publish this; a single share has no equivalent table, because nobody manages it to a benchmark.
The third: what it holds
The ten largest holdings with their weights, the split by sector, by region, and by asset type. Sum the ten weights for concentration; read the largest sector; check that the regions match the name. A "global" fund that is 70% one country is common and worth knowing.
The reading, as a checklist
Six questions, in this order, each answered from a line above. Which index? Since when? What fee, read in the right unit? How much turnover? How concentrated, at the top and by sector? Where is it domiciled? A fund that answers all six the way its name suggests is what it says it is. The exercises below are the checklist run on funds you have not seen in this course.
In the data
One more read the six questions do not ask: size. The same lines for a small thematic fund, to set beside the S&P 500 fund's total assets above:
A fund of tens of millions beside one of hundreds of billions, and the small one charging more than ten times the fee (29 September 2026). A fund that never gathers assets is a fund its sponsor may close, and a closure is a forced sale on a date the holder did not choose — with a taxable gain if there is one, and a gap in the portfolio until the money is placed again. The cheapest fund in a category is worth nothing if it is not there in three years; size is the read that says whether it will be.
Try it now
- Run the six-question checklist on AGG, a bond fund, from its record below. Two of the six will surprise you: its published holdings list is a single entry, and the top-ten weights mean little for a fund of thousands of bonds. Write down which questions this record cannot answer for a bond fund.
- Run it on GLD. One holding, 100% weight, and an expense ratio of 0.40% on a vault of metal. Say why a fund with one holding can still be what it claims.
- Pick any fund you have heard of and never looked inside. Open it in the Terminal (the link starts on VTI; change the symbol to yours), run the checklist, and write the one line whose answer you would not have guessed.
