Who owns historical valuations about equity such as stocks and index funds?
"I expect that data may be copyright. Data that's published (e.g. on a newsfeed or web site) is subject to terms of use. Standard & Poor's web site says, about the Shiller indexes, Who do I contact at S&P to license my   use of these indices?   Questions   regarding licensing the   S&P/Case-Shiller Home Price Indices   can be addressed to:  Bo Chung    Managing Director    bo_chung@standardandpoors.com,   +1.212.438.3519 As for 'recording' the information yourself, that may depend on how and where (e.g. from what source) you're recording it. If for example you tried to record prices from the Canadian MLS (Realtor's) network, they too have their own terms of use on the data they publish. Copyright laws vary from country to country (and terms of use certainly vary): for example see http://en.wikipedia.org/wiki/Feist_v._Rural which is case law about copyrighting a phone directory in the USA, and contrast that with http://en.wikipedia.org/wiki/Database_right which is European legislation. So who owns data if it is determined by free market? I guess that ""determined by free market"" means that buyers and sellers are publishing their offers-to-buy and their offers-to-sell, and I guess that the publisher (e.g. the stock exchange) has 'terms of use' about the data (the offers) that they're publishing."
"The textbook answer would be ""assets-liabilities+present discounted value of all future profit"".  A&L is usually simple (if a company has an extra $1m in cash, it's worth $1m more; if it has an extra $1m in debt, it's worth $1m less). If a company with ~0 assets and $50k in profit has a $1m valuation, then that implies that whoever makes that valuation (wants to buy at that price) really believes one of two things - either the future profit will be significantly larger than $50k (say, it's rapidly growing);  or the true worth of assets is much more - say, there's some IP/code/patents/people that have low book value but some other company would pay $1m just to get that. The point is that valuation is subjective since the key numbers in the calculations are not perfectly known by anyone who doesn't have a time machine, you can make estimates but the knowledge to make the estimates varies (some buyers/sellers have extra information), and they can be influenced by those buyers/sellers; e.g. for strategic acquisitions the value of company is significantly changed simply because someone claims they want to acquire it. And, $1m valuation for a company with $500m in profits isn't appropriate - it's appropriate only if the profits are expected to drop to zero within a couple years; a stagnant but stable company with $500m profits would be worth at least $5m and potentially much more." International equity are considered shares of companies, which are headquartered outside the United States, for instance Research in Motion (Canada), BMW (Germany), UBS (Switzerland). Some investors argue that adding international equities to a portfolio can reduce its risk due to regional diversification. "Shares do not themselves carry any identity. Official shareholders are kept at the registrar.  In the UK, this may be kept up to date and publicly accessible.  In the US, it is not, but this doesn't matter because most shares are held ""in street name"". For a fully detailed history, one would need access to all exchange records, brokerage records, and any trades transacted off exchange. These records are almost totally unavailable." A company as large as Home Depot will have a fairly robust Human Resources department and would probably be able to steer you in the right direction: odds are they know the name of the brokerage and other particulars. I did some googling around, their # is  (1-866-698-4347). Different states have different rules about how long an institution can have assets abandoned before turning them over to the state. California, as an example, has an abandoned property search site that you can use.  That being said, I had some penny stocks sitting in a brokerage account I never touched for about 20 years and when I finally logged back in there they were, still sitting there. You need a source of delisted historical data. Such data is typically only available from paid sources. According to my records, Lawson Software Inc listed on the NASDAQ on 7 Dec 2001 and delisted on 6 Jul 2011.  Its final traded price was $11.23.  It was taken over by Infor who bid $11.25 per share. Source: Symbol LWSN-201107 within Premium Data US delisted stocks historical data set available from http://www.premiumdata.net/products/premiumdata/ushistorical.php Disclosure: I am a co-owner of Norgate / Premium Data. The reason for such differences is that there's no source to get this information. The companies do not (and cannot) report who are their shareholders except for large shareholders and stakes of interest. These, in the case of GoPro, were identified during the IPO (you can look the filings up on EDGAR). You can get information from this or that publicly traded mutual fund about their larger holdings from their reports, but private investors don't provide even that. Institutional (public) investors buy and sell shares all the time and only report large investments. So there's no reliable way to get a snapshot picture you're looking for. Would bond holders differentiate in their EV/EBITDA calcs when compared to equity holders when valuing a private company?  For e.g. when it comes to a company that has built a power plant, generally equity holders would take an additional haircut/discount for the lack of marketability.   Would debt holders do the same? Would there be a higher valuation otherwise? Willis Group Holdings Set to Join the S&P 500; Fossil Group to Join S&P MidCap 400; Adeptus Health to Join S&P SmallCap 600 notes in part for the S & P case: Willis Group Holdings plc (NYSE:WSH) will replace Fossil Group Inc.   (NASD:FOSL) in the S&P 500, and Fossil Group will replace Towers   Watson & Co. (NASD:TW) in the S&P MidCap 400 after the close of   trading on Monday, January 4. Willis Group is merging with Towers   Watson in a deal expected to be completed on or about that date   pending final conditions. Post merger, Willis Group Holdings will   change its name to Willis Towers Watson plc and trade under the ticker   symbol “WLTW”. Fossil has a market capitalization that is more   representative of the midcap market space. As of Jan. 8, Fossil is about $1.44B in market cap and Willis is $21.02B for those wondering. Apple with a market cap of $540.58B is 3.26% of the index making the entire index worth approximately $16,582.21B, so Fossil is worth .00868% of the overall index for those wanting some numbers here. Thus, if a company acquires another and becomes bigger than there can be replacements made in those indices that have an artificial number of small members. Alternatively, a member may be removed for lack of representation where it is just so small compared to other companies that may be a better fit as some indices could be viewed as actively managed in a sense. In contrast, there are indices like those from Russell, known for the Russell 2000 small-cap index: Q: Why don't you reconstitute the indexes more often than once a year? A: Maintaining representative indexes must be weighed against the   costs associated with making frequent changes to index constituents   (namely, buying and selling stocks). The Russell Indexes are annually reconstituted because our research   has shown that this strikes a reasonable balance between accuracy and   cost. We originally reconstituted our indexes quarterly, then   semi-annually, but found these options to be suboptimal. Our extensive   research demonstrates that annual reconstitution accurately represents   the capitalization segments and minimizes the turnover required to   reflect the segments as they change. Thus there can be different scenarios.  Then there can be the effect on index funds when price-weighted indices like the Dow Jones Industrial Average has a member that does a stock split that causes some rebalancing too. On the DJIA Divisor: The Dow Jones Industrial Average (DJIA) is a price-weighted index that   is calculated by dividing the sum of the prices of the 30 component   stocks (Dow Jones Industrial Average components) by a number called   the DJIA Divisor or Dow Divisor . The index divisor is updated   periodically and adjusted to offset the effect of stock splits, bonus   issues or any change in the component stocks included in the DJIA.   This is done in order to keep the index value consistent. Don't have access to a Bloomberg, Eikon ect terminal but I was wondering if those that do know of any functions that show say, the percentage of companies (in different Mcap ranges) held by differing rates institutionally. For example - if I wanted to compare what percentage of small cap companies' shares are 75% or more held by institutions relative to large cap companies what could I search in the terminal? Check the answers to this Stackoverflow question https://stackoverflow.com/questions/754593/source-of-historical-stock-data a number of potential sources are listed "From How are indexes weighted?: Market-capitalization weighted indexes (or market cap- or cap-weighted   indexes) weight their securities by market value as measured by   capitalization: that is, current security price * outstanding shares.   The vast majority of equity indexes today are cap-weighted, including   the S&P 500 and the FTSE 100. In a cap-weighted index, changes in the   market value of larger securities move the index’s overall trajectory   more than those of smaller ones. If the fund you are referencing is an ETF then there may be some work to do to figure out what underlying securities to use when handling Creation and Redemption units as an ETF will generally have shares created in 50,000 shares at a time through Authorized Participants. If the fund you are referencing is an open-end fund then there is still cash flows to manage in the fund as the fund has create and redeem shares in on a daily basis. Note in both cases that there can be updates to an index such as quarterly rebalancing of outstanding share counts, changes in members because of mergers, acquisitions or spin-offs and possibly a few other factors. How to Beat the Benchmark has a piece that may also be useful here for those indices with many members from 1998: As you can see, its TE is also persistently positive, but if anything   seems to be declining over time. In fact, the average net TE for the   whole period is +0.155% per month, or an astounding +1.88% pa net   after expenses. The fund expense ratio is 0.61% annually, for a   whopping before expense TE of +2.5% annually. This is once again   highly statistically significant, with p values of 0.015 after   expenses and 0.0022 before expenses. (The SD of the TE is higher for   DFSCX than for NAESX, lowering its degree of statistical   significance.) It is remarkable enough for any fund to beat its   benchmark by 2.5% annually over 17 years, but it is downright eerie to   see this done by an index fund. To complete the picture, since 1992 the Vanguard Extended Index Fund   has beaten its benchmark (the Wilshire 4500) by 0.56% per year after   expenses (0.81% net of expenses), and even the Vanguard Index Trust   500 has beaten its benchmark by a razor thin 0.08% annually before   (but not after) expenses in the same period. So what is going on here? A hint is found in DFA's 1996 Reference   Guide: The 9-10 Portfolio captures the return behavior of U.S. small company stocks as identified by Rolf Banz and other academic   researchers. Dimensional employs a ""patient buyer"" discount block   trading strategy which has resulted in negative total trading costs,   despite the poor liquidity of small company stocks. Beginning in 1982,   Ibbotson Associates of Chicago has used the 9-10 Portfolio results to   calculate the performance of small company stocks for their Stocks,   Bonds, Bills, and Inflation yearbook. A small cap index fund cannot possibly own all of the thousands of   stocks in its benchmark; instead it owns a ""representative sample.""   Further, these stocks are usually thinly traded, with wide bid/ask   spreads. In essence what the folks at DFA learned was that they could   tell the market makers in these stocks, ""Look old chaps, we don't have   to own your stock, and unless you let us inside your spread, we'll   pitch our tents elsewhere. Further, we're prepared to wait until a   motivated seller wishes to unload a large block."" In a sense, this   gives the fund the luxury of picking and choosing stocks at prices   more favorable than generally available. Hence, higher long term   returns. It appears that Vanguard did not tumble onto this until a   decade later, but tumble they did. To complete the picture, this strategy works best in the thinnest   markets, so the excess returns are greatest in the smallest stocks,   which is why the positive TE is greatest for the DFA 9-10 Fund, less   in the Vanguard Small Cap Fund, less still in the Vanguard Index   Extended Fund, and minuscule with the S&P500. There are some who say the biggest joke in the world of finance is the   idea of value added active management. If so, then the punch line   seems to be this: If you really want to beat the indexes, then you   gotta buy an index fund." "I had  both closing price and adjusted price of Apple showing the same amount after ""download data"" csv file was opened in excel. https://finance.yahoo.com/quote/AAPL/history?period1=1463599361&period2=1495135361&interval=div%7Csplit&filter=split&frequency=1d Its frustrating. My last option was to get the dividends history of the stock and add back to the adjusted price to compute the total return for a select stock for the period." If you use Google Finance, you will get incorrect results because Google Finance does not show the dividend history. Since your requirement is that dividends are re-invested, you should use Yahoo Finance instead, downloading the historical 'adjusted' price. "The Securities Industry and Financial Markets Association (SIFMA) publishes these and other relevant data on their Statistics page, in the ""Treasury & Agency"" section. The volume spreadsheet contains annual and monthly data with bins for varying maturities. These data only go back as far as January 2001 (in most cases). SIFMA also publishes treasury issuances with monthly data for bills, notes, bonds, etc. going back as far as January 1980. Most of this information comes from the Daily Treasury Statements, so that's another source of specific information that you could aggregate yourself. Somewhere I have a parser for the historical data (since the Treasury doesn't provide it directly; it's only available as daily text files). I'll post it if I can find it. It's buried somewhere at home, I think." "What in the world to shareholders have to do with it?  Nowadays, the vast majority of the shares in most big corporations are ""owned"" via intermediaries (i.e. mutual funds and 401K's, IRA's and Pension Funds) that do not ALLOW the actual end owners to have any say whatsoever.  All those investment vehicles *allow* people to care about ... is the share price."
