S&P reports: number of shareholders?
"Yes these are the number of shareholders that are not held in ""street name"" plus the different brokerages that hold the shares in ""street name"".  So the stat is pointless since it really only lists the few people who own the stocks outside of a brokerage account and a bunch of wall street brokers."
I almost agree. I am not completely sure about the ownership of stock, but to have the majority ownership of any company you must own more than 50% of a company's outstanding shares. Although a board in majority, could out vote a majority shareholder in most cases depending on the company policy regarding shareholders and the general law of the country, and to how the company is managed. You won't be able to know the trading activity in a timely, actionable method in most cases. The exception is if the investor (individual, fund, holding company, non-profit foundation, etc) is a large shareholder of a specific company and therefore required to file their intentions to buy or sell with the SEC. The threshold for this is usually if they own 5% or greater of the outstanding shares. You can, however, get a sense of the holdings for some of the entities you mention with some sleuthing. Publicly-Traded Holding Companies Since you mention Warren Buffett, Berkshire Hathaway is an example of this. Publicly traded companies (that are traded on a US-based exchange) have to file numerous reports with the SEC. Of these, you should review their Annual Report and monitor all filings on the SEC's website. Here's the link to the Berkshire Hathaway profile. Private Foundations Harvard and Yale have private, non-profit foundations. The first place to look would be at the Form 990 filings each is required to file with the IRS. Two sources for these filings are GuideStar.org and the FoundationCenter.org. Keep in mind that if the private foundation is a large enough shareholder in a specific company, they, too, will be required to file their intentions to buy or sell shares in that company. Private Individuals Unless the individual publicly releases their current holdings, the only insight you may get is what they say publicly or have to disclose — again, if they are a major shareholder. You can calculate the fully diluted shares by comparing EPS vs diluted (adjusted) EPS as reported in 10K. I don't believe they report the number directly, but it is a trivial math exercise to reach it. The do report outstanding common stock (basis for EPS). If a company is public, and they record a 2016 profit of 100mil. Say there is shareholder A and shareholder B who are both wealthy and own 25% each of the company. Say the remaining 50% of shares are owned by a number of funds/small time investors.   So 2016 profits are 100mil, lets say there is a dividend. Can the company still award a larger share of profits to the two big shareholders? I.e. say 50 mil of the profits go into dividend payments and another 20 mil as retained earnings to be reinvested into future projects, can the remaining 30 mil of profits be split and given to shareholders A and B? One of my university professors suggested doing this systematically to get access to shareholder meetings where there is typically a nice dinner involved. As long as the stock price + commission is less than the price of a nice restaurant it's actually not a bad idea. Market cap should be share price times number of shares, right? That's several orders of magnitude right there... This is a good reminder for investors to be skeptical of M&amp;A with respect to shareholder value creation.  &gt; S&amp;P Global Market Intelligence Quantamental Research, a research arm of the ratings agency, has updated a study on the impact of deals on the acquiring company’s share price. The study looked at M&amp;A deals done by listed companies in America’s Russell 3000 index between January 2001 and August 2017; deals were only included if they cost more than 5% of the total enterprise value of the acquirer (5% of the equity value, for financial companies). The acquirers’ shares underperformed the market ([see chart](https://cdn.static-economist.com/sites/default/files/imagecache/640-width/images/print-edition/20171007_FNC817_1.png)) and those of rival firms in the same industry. Your observation is mostly right, that 1 is a the number around which this varies.  You are actually referencing PEG, P/E to Growth ratio, which is a common benchmark to use to evaluate a stock. The article I link to provides more discussion. (yes, this should probably be a comment, not an answer ... but it's a bit long). I don't know what the laws are specifically about this, but my grandfather used to be on the board of a company that he helped to found ... and back in the 1980s, there was a period when the stock price suddenly quadrupled One of the officers in the company, knowing that the stock was over-valued, sold around a third of his shares ... and he got investigated for insider trading.  I don't recall if he was ever charged with anything, but there were some false rumors spreading about the company at the time (one was that they had something that you could sprinkle on meat to reduce the cholesterol).  I don't know where the rumors came from, but I've always assumed it was some sort of pump-and-dump stock manipulation, as this was decades before they were on the S&P 500 small cap. After that, the company had a policy where officers had to announce they were selling stock, and that it wouldn't execute for some time (1? 2 weeks? something like that).  I don't know if that was the SEC's doing, or something that the company came up with on their own.

Also, there is also the 'Views and News' part of the web page which has additional information beyond what exist in the reports. You're only counting one year.   Let's say 30 years of data, minutewise, for 2,000 stocks, and 50 characters per data line. That's 1.5TB of data.  Since the market has grown, that's an overestimate - 30 years ago there weren't 2,000 stocks in the NYSE - but it still gives us ballpark of roughly 1 TB.  Not an easy download. Well, you can just say that 1 dollar contributed = one share and pay out dividends based on number of shares. That makes it pretty easy to make things fair based. There are pros and cons with this pooling approach. If you have a public company and shareholder A owns 25% and shareholder B owns 25%, and lets say the remaining 50% is owned by various funds/small investors.   Say profits are 100mil, and a dividend is payed. Say 50 mil worth is payed out as dividend and 30 mil is kept as retained earnings for future investment. Can the remaining 20 mil be distributed to shareholders A and B, so that they both get 10mil each? Can certain shareholders be favored and get a bigger cut of profits than the dividends pay out is my question basically. Join me for a look at the Quote for SPY.  A yield of 1.82%. So over a year's time, your $100K investment will give you $1820 in dividends.  The Top 10 holdings show that Apple is now 3% of the S&P. With a current dividend of 2.3%. Every stock in the S&P has its own different dividend. (Although the zeros are all the same. Not every stock has a dividend.) The aggregate gets you to the 1.82% current dividend. Dividends are accumulated and paid out quarterly, regardless of which months the individual stocks pay. "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."
