GAAP or non-GAAP numbers in nasdaq.com?
You're interpreting things correctly, at least at a high level. Those numbers come from the 10Q filing and investor summary from Microsoft, but are provided to NASDAQ by Zacks Investment Research, as noted on the main page you linked to.  That's a big investment data firm.   I'm not sure why they reported non-GAAP Microsoft numbers and not, say, AAPL numbers; it's possible they felt the non-GAAP numbers reflect things better (or have in the past) for some material reason, or it's possible they made a typo, though the last three quarters at least all used non-GAAP numbers for MSFT.  MSFT indicates that the difference in GAAP and non-GAAP revenue is primarily deferred revenue (from Windows and Halo). I did confirm that the SEC filing for MSFT does include the GAAP number, not the non-GAAP number (as you'd expect). I will also note that it looks like the 10Q is not the only source of information.  Look at ORCL for example: they had in the March 2016 report (period ending 2/29/16) revenues of .50/share GAAP / .64/share non-GAAP.  But the NASDAQ page indicates .59/share for that quarter. My suspicion is that the investment data firm (Zack's) does additional work and includes certain numbers they feel belong in the revenue stream but are not in the GAAP numbers.  Perhaps MS (and Oracle) have more of those - such as deferred software revenues (AAPL has relatively little of that, as most of their profit is hardware).
A Section 1256 contract is any: Non-equity options include debt options, commodity futures options, currency options, and broad-based stock index options. A broad-based stock index is based upon the value of a group of diversified stocks or securities (such as the Standard and Poor's 500 index). 60% of the capital gain or loss from Section 1256 Contracts is deemed to be long-term capital gain or loss and 40% is deemed to be short-term capital gain or loss. What this means is a more favorable tax treatment of 60% of your gains. http://www.tradelogsoftware.com/tax-topics/futures/ It's a really wierd rule (arbitraty 60% designation, so broad, etc), but section 1256 contracts get preferential tax treatment and that's what Buffett's talking about. I appreciate it. I didn't operate under selling the asset year five but other than that I followed this example. I appreciate the help. These assignments are just poorly laid out. Financial management also plays on different calculation interactions  so it is difficult for me to easily identify the intent at times. Thanks again. I will assume that you are not asking in the context of high frequency trading, as this is Personal Finance Stack Exchange. It is completely acceptable to trade odd lots for retail brokerage customers. The odd lot description that you provided in your link, from Interactive Brokers is correct. But even in that context, it says, regarding the acceptability of odd lots to stock exchanges: The exception is that odd lots can be routed to NYSE/ARCA/AMEX, but   only as part of a basket order or as a market-on-close (MOC) order. Google GOOG is traded on the NASDAQ. Everything on the NASDAQ is electronic, and always has been. You will have no problem selling or buying less than 100 shares of Google.  There is also an issue of higher commissions with odd lots: While trading commissions for odd lots may still be higher than for   standard lots on a percentage basis, the popularity of online trading   platforms and the consequent plunge in brokerage commissions means   that it is no longer as difficult or expensive for investors to   dispose of odd lots as it used to be in the past. Notice what it says about online trading making it easier, not more difficult, to trade odd lots. I think you're looking for the public float: Public float or the unqualified term may also refer to the number of   outstanding shares in the hands of public investors as opposed to   company officers, directors, or controlling-interest investors.   Assuming the insider held shares are not traded, these shares are the   publicly traded ones. The float is calculated by subtracting   restricted shares from outstanding shares. As mentioned, Treasury stock is probably the most narrow definition of restricted stock (not publicly traded), but shares held by corporate officers or majority investors are often included in the definition as well. In any case, the balance sheet is indeed a good place to start. It turns out that in this special case for New York, they have a law that says that if you are changing your filing status from resident to nonresident, you must use the accrual method for calculating capital gains. So in this case, the date on the papers is the important one. Ya, that's a lot of data - especially considering your relative lack of experience and the likely fact that you have no idea what to do with what you're given.  How do you even know you need minute or tick-based bid-ask data?    You can get a lot more than OHLC/V/Split/Dividend.  You can get:  * Book Value; * Dividend information (Amount, yield, ex date, pay date); * EBITDA; * EPS (current AND estimates); * Price/sales ratio; * Price/book value; * Price/earnings ratio; * PEG ratio; * Short ratio; * Market cap.  Among other things, all for free. "At the bottom of Yahoo! Finance's S & P 500 quote Quotes are real-time for NASDAQ, NYSE, and NYSE MKT. See also delay   times for other exchanges.

"A non-trading stock or non-marketable security or unlisted security is one that does not trade continually on an exchange. For tax purposes, this can mean a whole new ball of wax which I would prefer the experts address with an edit to this answer or a new answer. For financial accounting purposes, this is when, say, one owns shares in an unlisted corporation and should be treated very carefully less one delude oneself. For trading stock, the value can be known immediately by checking any valid data provider's price and marking to market.  For non-trading stock, the value has to be ""marked to model"".  This can get one into Enron sized trouble. In this case, it's best to either leave the value of the stock at the purchase price and recognize gains upon sale, use a price from another honest transaction by third parties which are most likely difficult to attain, or to use some shorthand measure like applying the market P/E. Be wary of strangely high figures for value from the purchase price by using a market average, and don't throw away the shares just yet if a strangely low one arises.  This method can lead to strange results." Appreciate the good back and forth. I only did equity for a brief while before I moved to emerging market debt. I can go across capital structure but we don't spend much time on retail outside of China. I think EBITDA or an adjusted NI makes a lot more sense than FCF for Amazon, and nowadays, FCF is ALL that I use for valuation in EM debt world. "The official source is the most recent Form 13F that Berkshire Hathaway, which is  filed with the Securities & Exchange Commission on a quarterly basis .  You can find it through the SEC filing search engine, using BRKA as the ticker symbol. and then looking for the filings marked 13-FR or 13-FR/A (the ""/A"" indicates an amended filing).   As you can see by looking at the 13-F filed for the quarter ending September 30  , the document isn't pretty or necessarily easy to read, hence the popularity of sites such as those that Chad linked to. It is, though, the truly official source from which websites tracking the Berkshire Hathaway portfolio derive their information." As I write this, the NASDAQ Composite is at 2790.00, down 6.14 points from yesterday. To calculate the percentage, you take 6.14 and divide by yesterday's close of 2796.14 to yield 0.22%. In your example, if SPY drops from 133.68 to 133.32, you use the difference of -0.36 and divide by the original, i.e. -0.36/133.68 = -0.27%. SPY is an ETF which you can invest in that tracks the S&P 500 index. Ideally, the index would have dropped the same percentage as SPY, but the points would be different (~10x higher). To answer your question about how one qualifies a point, it completely depends on the index being discussed. For example, the S&P 500 is a market-capitalization weighted index of the common stock of 500 large-cap US public companies. It is as if you owned every share of each of the 500 companies, then divide by some large constant to create a number that's easily understood mentally (i.e. 1330). The NASDAQ Composite used the same methodology but includes practically all stocks listed on the NASDAQ. Meanwhile, the Dow Jones Industrial Average is a price-weighted index of 30 large-cap companies. It's final value is modified using a divisor known as the Dow Divisor, which accounts for stock splits and similar events that have occurred since a stock has joined the index. Thus, points when referring to an index do not typically represent dollars. Rather, they serve as a quantitative measure of how the market is doing based on the performance of the index constituents. ETFs like SPY add a layer of abstraction by creating an investible vehicle that ideally tracks the value of the underlying index directly. Finally, neither price nor index value is related to volume. Volume is a raw measurement of the total number of shares traded for a given stock or the aggregate for a given exchange. Hope this helps! "There is no numerical convention in finance that I have ever seen.  If you look at statements or reports that measure growth when the starting value is negative or zero, you typically see ""n/a"" or ""-"" or ""*"" as the result.  Any numerical result would be meaningless.  Suppose you used 100% and another company had a legitimate 150% gain - where would the 100% change rank? What do my manager and investors expect to see? As a financial analyst - I would not want to see 100%.  I would instead rather see something that indicates that the % change is meaningless.   As an example, here's the WSJ documentation on change in Net Income: Net Income percent change is the change from the same period from a year ago. Percent change is not provided if either the latest period or the year-ago period contains a net loss.  Thinking about it in another context: Yesterday you and your friend had no apples. Today you have 1 and your friend has 20.  What percentage increase did you both have? Did you both have a 100% increase? How can you indicate that your friend had a larger ""increase""? In that case (and in finance), the context needs to turn from a percentage increase to an absolute increase.  A percentage increase is that scenario is meaningless." "Since doodle77 handled arbitrage, I'll take goodwill.  Goodwill is an accounting term that acts much like a ""plug"" account: you add/subtract to it the amount that makes everything balance.  In the case of goodwill, it generally only applies to mergers &amp; acquisitions.  The theory (and justification) is this: firms buy other firms at prices other than the market price (usually higher), and it is assumed that this is because the acquirer values its acquisition more than other people do.  But whether you use historical prices or market prices when you add (subtract) assets and liabilities to to (from) your balance sheet, this will never add up, because you paid more (less) than the assets are worth in the market, so more (less) cash flowed out than assets flowed in.  The difference goes into the goodwill account, so firms with a large goodwill account are ones that have made lots of acquisitions." On NASDAQ the ^ is used to denote other securities and / to denote warrents for the underlying company. Yahoo maybe using some other designators for same. "The 3-letter tickers are from a different era.... Nowadays the usage of tickers is more of a ""legacy"" tradition rather than a current necessity. As such they're no longer limited to 3 characters. And the characters don't have to be related to the actual name. For example a company named Alphabet is trading on NASDAQ under the ticker ""GOOGL"". It has 5 characters, not 3, and (almost) none of them appear in the name of the company (used to, but not anymore)."
