Do I have to read the prospectus before buying an index fund?

Post by ebaron »

Before buying an index fund, should I read its prospectus from cover to cover? I don't want any surprises, so should I always read 100+ pages for every index fund that I want to buy? How do passive investors conduct comprehensive research? Most people do not have time to read thousands of pages of documents written in legal language.

The Vanguard index fund prospectuses are very much shorter than you indicate. If the fund has a massive propectus, I would worry that it is not a simple cap weighted fund. I would not by an index fund that is not simple cap weighted.

You could find another fund, or try to figure out what this one is doing that requires all that detail. You suggest you are not interested in reading a long document to figure it out. So just buy a simple fund with a simple prospectus.

I would read the prospectus of the fund you choose. How else are you going to know what it says?

It would be far better to spend an hour educating yourself about how index funds operate than to read the legal language in a mutual fund prospectus. If you're dealing with a vanilla type SP500 or Total Market Index fund you just need to understand the nature of the underlying index, the expense ratio and the tracking error that the management has delivered.

I skim a prospectus, to make sure it is what it says it is.

Case in point, did you know the Fidelity ZERO funds can not be transferred to another brokerage? We all talk about moving funds around say to move $100k to BOA to get their premier rewards.. Well, you can't do that with Fidelity ZERO investments in a taxable account. They will not ACAT.

Which index fund has a 100 page prospectus? I read them at some point before or during ownership.

No, they do not. I last read a prospectus in the 1980s I think. You should read at least 3 to 10 prospectuses in your lifetime. It won't kill you. But after 10 of them, you might only read the ones of unusual non-mainstream investments.

Doesn't this expose you to the risk of buying something that you would not otherwise buy if you had read the prospectus?

I do if it's something uncommon or that I don't trust (i.e. anything in my workplan).
If it's a Schwab or Vanguard fund, then I don't.

I flip to the back page of the full (not Summary) Prospectus, and spend 1 minute on the "financial highlights" table. (Usually it is the last page, not always).

I ensure the annual return numbers, expense ratio, dividend & cg distributions, and turnover passes my sniff test.

For an actively managed fund (which I haven't bought in ages), I used to read the first few pages of text about the investing approach.

I don't read them. I do use a prospectus frequently to look things up from time to time - to find out what index the fund follows or what the expense ratio is.

Once you have a good grasp of what an index fund is and how they work, most of what you want to know is plain from the name of the fund. If you want to do comparison shopping between two similar funds/ETFs, you might have to actually read more of the prospectus.

Will you be have a better understanding of what is going on if you read everything? If yes, go for it.

A consolidated strategy is to understand what the index means, and a general idea of what holdings are in the fund. For example, if you are buying an equity fund, say S&P 500, skim the list of the company stocks you are purchasing via the fund.

Most importantly, you should be aware of risks, potential benefits, and fees involved with your funds, and how they align with your personal goals. If taxable, understand how often you should expect holdings to turn over and when dividends are paid. You don't want to sell during the wash sale period of a dividend payout, unless you don't mind triggering wash sale complications/record keeping on your taxes.

If I were investing in a narrow sector index kinda thing then I'd make the time to slog through the prospectus on the off chance any of it wasn't written in legalese.

But now that I think of it I could probably find the time to review 'em given I've had the same handful of funds for several decades now ;-)

As long as it's a 'plain vanilla index fund' like VTSAX, nope. I know how the fund works and the risks involved.

But with more exotic funds like leveraged ETFs or ETNs, it's a really good idea to read the prospectus.

Read enough to avoid surprises, and ensure you are investing in what you intended.
Often the Summary Prospectus will suffice. It's short, and has more plain English than legalize. If that doesn't tell you what you need to know, then at least skim the full Prospectus.

Re: Do I have to read the prospectus before buying an index fund?

Post by nisiprius »

Yes.

Why? Because even though they may sort of conceal this in the form of a simple checkbox, in order to buy a mutual fund you are actually signing a legal document in which you say that you did. Personally I am not willing to fib on legal documents that I sign.

Is this meaningless? No, it isn't. It takes a while to decide how to "read" the prospectus but there really are things to look at. For example (a real one), if a guru says that a certain mutual fund is "passive," but the prospectus says "The Fund is actively managed," that doesn't mean you shouldn't buy the fund but it does mean there is a question you should get answered to your satisfaction before you buy it.

Another example. Every prospectus AFAIK--both the "summary" and "statutory" ones--contains a list of "Principal Risks of Investing in the Fund." For the Vanguard Total Stock Market Index Fund, the summary prospectus lists two:
Principal Risks
The Fund is subject to the following risks, which could affect the Fund’s performance:
  • Stock market risk, which is the chance that stock prices overall will decline. Stock markets tend to move in cycles, with periods of rising prices and periods of falling prices. In addition, the Fund’s target index may, at times, become focused in stocks of a particular market sector, which would subject the Fund to proportionately higher exposure to the risks of that sector.
  • Index sampling risk, which is the chance that the securities selected for the Fund, in the aggregate, will not provide investment performance matching that of the Fund’s target index. Index sampling risk for the Fund is expected to
    be low.
That is the full list of risks and their full descriptions.

The Wisdomtree Emerging Markets SmallCap Dividend Fund is also an index fund; it "employs a 'passive management' or indexing investment approach designed to track the performance of the Index." However, it lists nineteen principal risks, with a paragraph about each one (which I haven't included).
  • Emerging Markets Risk.
  • Small-Capitalization Investing Risk.
  • Dividend Paying Securities Risk.
  • Investment Risk.
  • Market Risk.
  • Shares of the Fund May Trade at Prices Other Than NAV.
  • Capital Controls and Sanctions Risk.
  • Cash Redemption Risk.
  • Currency Exchange Rate Risk.
  • Cyber Security Risk.
  • Foreign Securities Risk.
  • Geographic Investment Risk.
  • Geopolitical Risk.
  • Index and Data Risk.
  • Information Technology Sector Risk.
  • Investment Style Risk.
  • Issuer-Specific Risk.
  • Non-Correlation Risk.
  • Non-Diversification Risk.
You might judge that many of these are trivial, or that you don't even see them as risks. Furthermore, many would choose to take these risks because in investing, you hope to be rewarded for taking risk and they think the benefits outweigh the risks. Nevertheless, you should take the time and make the judgement, particularly with any that aren't already familiar to you. In this particular case, for example, "non-diversification risk" catches my eye.

Also, I would say that the harder it is to find the prospectus on a fund company's website, the more important it is that you actually bother to find it and read it.

That said, big, broadly-diversified mainstream index funds are not likely to have surprises in the prospectus, and looking them over will be something of a waste of time--although it will give you practice in what a straightforward prospectus looks like so that you will be more ready to spot odd things in less-straightforward ones.

I think the summary prospectus is fine. And "read" doesn't need to be taken too literally. It helps to go in with a mental list of "questions I have about this fund" and see if you can find the answers in the prospectus.

Likewise - before I give someone $30K of my hard-earned money to invest - I read the prospectus.

Sure it does. But I am in my 60s and I am not buying non-mainstream investments.

I will say that in 2008 I did exchange into a "Government Securities" bond fund in my employer's 401(k) that was run by Morgan Stanley at the time. It turns out that the prospectus said that up to 20% of the fund could be invested in junk. And Morgan Stanley got caught holding Countrywide bonds, so they unloaded those bonds into that allowed 20% fraction of that Morgan Stanley US Government Securities bond fund in order to save their butts. Unfortunately, their clients and people who had that fund in their 401(k) were screwed. That bond fund dropped more than 10% in a few weeks.

The several funds that I own have all been thoroughly discussed and torn apart on this forum. I trust the analysis here far more than what it probably contained in the prospectus. I suppose if I was going to buy something novel I would read the prospectus.

Most of my money is in a 401k with CIT funds that all I get is a one page fund fact sheet. I've read that. I've also read a number of, but not all a few samples of annual reports of a few funds we own. But I see zero reason for the average investor to read the fund prospectus of a major index fund from a major provider. The basic information is shown online in the funds website.

Checking the portfolios of these two funds shows the peril of relying on prospectuses to inform about risk:

28% of Vanguard Total Stock Market Index Fund is in information technology
22% of Wisdomtree Emerging Markets SmallCap Dividend Fund is in information technology

Yet only the Wisdomtree fund lists "Information Technology Sector Risk" as a principal risk. Checking for "Information Technology Sector Risk" in the prospectuses leads to the wrong conclusion about which fund has more concentrated exposure there.

1. A better question would be: Do I have to understand the prospectus before buying an index fund?

2. A follow up would be: How many on this forum could explain, line by line, the prospectus to their favorite index fund?

My guess would be:

1. No

2. Maybe 10%

Unfortunately, it is very, very common, if not universal, for the prospectus to contain language like this, from the Statutory prospectus for Total Stock
Under normal circumstances, each Fund will invest at least 80% of its assets in the stocks that make up its target index.
The percentage always seems to be "80%." Now my personal opinion is that this sucks.

Then, too, this is only under "normal" circumstances--and elsewhere the Vanguard prospectus notes that "Vanguard reserves the right to change its policies without notice to shareholders!"

It's necessary to look at the annual and semiannual reports and other holdings disclosures to get some idea of what the fund is truly investing in. In the case of many funds, it turns out that when you look at the holdings, the percentage invested in The Stuff You Thought It Was Invested In is much much higher than 80%... 1% here in cash, 0.2% there in mysterious derivatives, 0.1 in "other," but you know, 98% in what you thought. The June 30, 2020 semiannual report for Total Stock says that it has "0.0%" in preferred stocks! In this case, $3,296,000 out of $867,925,992,000 = 0.00038%. Did I do that correctly? I thought I had basic numeracy but I would not have guess that $3 million worth of preferred stocks would round to 0.000%!

At one point the Fidelity [Spartan] Total Market Index Fund had about 4% invested in international stocks, but, you know, still over 95% in US stocks...

The protection from that is not so much reading the prospectus but a due diligence checklist that includes a line item disallowing investing in mutual funds run by investment banks (precisely because of the risk that they become graveyards for illiquid securities on the investment bank's balance sheet).

Reading certain parts of the Statement of Additional Information is also useful, particularly any sections on soft dollar arrangements with brokers, and any sections on securities lending.

I think it is part of the statutory prospectus from a legal contract perspective, so I assume nisiprius has read SAI's cover to cover for funds invested in.

Wow. Do you prospectus readers also read End User License Agreements (EULA)? If you say yes, I’m not sure I believe you. But, if you truly do, I’m impressed on both counts.

FWIW, I don’t read prospectus or EULAs. I am not worried that my not reading Vanguard’s Prospectus for Total Stock will keep me ignorant of some dastardly actions of theirs. I have seen evidence (Cambridge Analytica) that Facebook, regardless of what their EULA says, does dastardly things with data. I have long ago deleted my Facebook account and wish that I’d never opened one.

I do not read them cover to cover. I will take a glance for certain information, especially what index they track, how that is determined, and the number of holdings. One thing I want to know is whether a ETF is different enough to serve as a tax loss harvesting partner to my current positions.

If you are investing in something other than total market/S&P500 you will want to know how they select their stocks compared with peers. "Small Value" or "Quality" may mean different things to different funds.

I actually skim these because I'm always curious at what the company or product actually outlines what they do. Especially so if it's anything related to financial endeavors.

It's why earlier this year when brokerages were limiting trades, investors were so shocked that brokerages could do that, even though it's in the agreements they signed. Apparently if the investors would have done their due diligence just a step further they would have understood an additional risk.

Yeah I read it once before I bought my first Vanguard index fund. Why? Because I’m curious and want to learn. What did I learn? Well, it’s index fund, which tracks a benchmark. There’s no vettinng, stock picking, awesome looking fund managers that you need to look for. I wanted to see if there are other things going on such as securities lending, cost, internal control, record keeping, trading restrictions, etc., you know... the accounting stuff. But at the end of the day, it’s an index fund!

I read 10K and 10Q on regular basis, so I know to get to the right section that I want to look for. I don’t read word by word, cover to cover, if that what you mean.

Why would I read the prospectus for an index fund? The purpose of it is to track an index.. it's easy to check if it's doing that without reading a document.

For a plain vanilla index fund from a major provider? No. I have read too many. But I do review them on occasion.

Most are boiler plate. They get updated every year. The annual report and index methodology are more important.

I never read them. I've saved hours and hours by not reading them. I also don't read the terms and conditions that come with my credit cards. Life is too short to play amateur lawyer.

This.

I don't call my brokerage to inquire why this year's dividends are scheduled later than last year, I don't mail in paper tax forms, and I've never read a prospectus. Better things to do.

If I trust the company, I believe they are selling just what they advertise and do not get all lawyerly about it. If Vanguard calls VFIAX an S&P500 cap-weighted index fund I believe them. So, no, I don't generally read the prospectus.

I do occasionally look through their "summary prospectus" which is an easier read than their "statutory prospectus." For VFIAX the summary is 8 pages and the statutory is 48 pages.

P.S. If there was something fishy about VFIAX I'm sure I'd hear about it here! Heck, there is even discussion about the size of the Total Market haystack!

since I employ a long term strategy with a minimal amount of funds, its not often i'm required to read a prospectus but I certainly check on any of my actively managed funds from time to time.

No, they do not. I last read a prospectus in the 1980s I think. You should read at least 3 to 10 prospectuses in your lifetime. It won't kill you. But after 10 of them, you might only read the ones of unusual non-mainstream investments.
Doesn't this expose you to the risk of buying something that you would not otherwise buy if you had read the prospectus?
There was a thread by a poster who was outraged that their fund had been doing exactly what the prospectus said it would do, rather than what the poster assumed it would be doing. Based on nothing other than the name of the fund. The complainant was vehement in their expressed opinion that funds should do what they assumed they would do and they should not read a prospectus.

It was both sad and funny.

Let me give you this point of view.

We have a fixed number of days, hours, minutes in our life. We have to invest this just like our money.

If you want to spend your time reading a prospectus in detail, I would ask - what do you think you're going to get out of it? If you want enjoyment and to start learning more about mutual funds, then that's fine - reading the prospectus is entertainment and some education.

I wouldn't try to convince yourself that reading a prospectus will lead you to better investments in most situations. Your time is probably better spent elsewhere, because to get to a point where you're actually making informed, educated decisions based on a prospectus is a matter of thousands of hours of education (and even then, the jury is out on whether this is possible).

Don't hear this as "just invest blindly". Do hear this as "there are more efficient ways to get the same information as what is in the prospectus".

I flipped through the vanguard 500 prospectus recently. It was slightly interesting. I remember it being closer to ten pages or so of small font. It didn’t change my thoughts on it either way. I was happy to pay such a low expense ratio for how well it tracked the s&p 500 and how frequently it beats out the majority of highly paid wall street fund managers.

If I wanted to spend time thinking about my investments, I would spend it investing in individual stocks rather than reading a prospectus for an index fund. The whole point (for me) of index funds is that I don't have to think about it at all.

ebaron wrote: Mon Oct 12, 2020 10:19 am Before buying an index fund, should I read its prospectus from cover to cover? I don't want any surprises, so should I always read 100+ pages for every index fund that I want to buy? How do passive investors conduct comprehensive research? Most people do not have time to read thousands of pages of documents written in legal language.
The summary prospectus for Vanguard Total Stock Market Index is 8 pages long, including the cover page, a page left intentionally blank, and the back cover. In other words there are 5 pages of words. https://personal.vanguard.com/pub/Pdf/s ... 2210171781

The full prospectus, also called the statutory prospectus is 68 pages long. It's here: https://personal.vanguard.com/pub/Pdf/p ... 2210171687

You should read the summary prospectus, then see what's in the full prospectus that you a) care about and b) don't understand.

There is also a 68 page Statement of Additional Information here: https://personal.vanguard.com/pub/Pdf/s ... 2210171260

The real questions should be:

- what my mutual fund can and is investing in?
- do I understand what measurement my fund's returns are measured against?
- do I understand the fees I am being charged?
- does this fund meet my investment objectives?

I haven't read a prospectus in many, many years. But I only have mutual funds that are huge, wildly popular, and figure anything controversial would be all over the news and forums. :shock:

This is my thinking as well. Similar to me trusting financial experts about why diversification is important without delving into the relevant journal articles.

VTSAX contains thousands of American companies of all different shapes and sizes, and has consistently outperformed the majority of actively managed funds when fees are taken into account. What more do I really need to know?

The great thing about the BH philosophy is that you don't have to think too deeply about your investments to do pretty well in the end.

No you don't have to.

I used to read them, and I read almost every contract, but I have given up on prospectuses (prospecti???) and EULAs for technology products.

There are only so many hours in a day.
