Google market cap
You are right: if the combined value of all outstanding GOOG shares was $495B, and the combined value of all GOOGL shares was $495B, then yes, Alphabet would have a market cap of at least $990B (where I say at least only because I myself don't know that there aren't other issues that should be in the count as well). The respective values of the total outstanding GOOG and GOOGL shares are significantly less than that at present though. Using numbers I just grabbed for those tickers from Google Finance (of course), they currently stand thus:
"Short answer: google finance's market cap calculation is nonstandard (a.k.a. wrong). The standard way of computing the market capitalization of a firm is to take the price of its common stock and multiply by the number of outstanding common stock shares.  If you do this using the numbers from google's site you get around $13.4B.  This can be verified by going to other sites like yahoo finance and bloomberg, which have the correct market capitalization already computed. The Whole Foods acquisition appears to be very cut-and-dry.  Investors will be compensated with $42 cash per share. Why are google finance's numbers wrong for market cap?  Sometimes people will add other things to ""market capitalization,"" like the value of the firm's debt and other debt-like securities.  My guess is that google has done something like this.  Whole Foods has just over $3B in total liabilities, which is around the size of the discrepancy you have found." 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. The difference between the two numbers is that the market size of a particular product is expressed as an annual number ($10 million per year, in your example).  The market cap of a stock, on the other hand, is a long-term valuation of the company. "When you look at those results you'll see that it lists the actual market cap for the stocks.  The ones on the biggest price move are usually close the the $1B capitalization cut-off that they use. (The don't report anything with less than $1B in capitalization on these lists.)  The ones on the biggest market cap are much larger companies. So, the answer is that a 40% change in price on a company that has $1B capitalization will be a $400M change in market cap.  A 4% change on a company with $100B capitalization will be a $4B change in market cap.  The one that moved 40% will make the ""price"" list but not the market cap list and vice versa." That seems like a very high valuation. 2 years ago in the Ellen Pao lawsuit Pao's side claimed Reddit was worth $250mm, and the press had claimed it was $500mm. Either Reddit's valuation has more than tripled in 2 years, or this article is misleading. You can invest upto $200K per year abroad, and yes, you can buy Google as a stock. Consider opening an international account with a broker like interactive brokers (www.interactivebrokers.co.in) which allows you to fund the account from your local Indian account, and then on, buy shares of companies listed abroad. "Market Capitalization is the value the market attributes to the company shares calculated by multiplying the current trading price of these shares by the total amount of shares outstanding. So a company with 100 shares trading at $10 has a market cap of $1000. It is technically not the same as the value of a company (in the sense of how much someone would need to pay to acquire the company), Enterprise value is what you want to determine the net value of a company which is calculated as the market capitalization + company debt (as the acquirer has to take on this debt) - company cash (as the acquirer can pocket this for itself). The exact boundary for when a company belongs to a certain ""cap"" is up for debate. For a ""large cap""  a market capitalization of $10 billion+ is usually considered the cutoff (with $100+ billion behemoths being called ""mega caps""). Anything between $10 billion and ~$1 billion is considered ""mid cap"", from ~$1billion to ~$200 million it's called a ""small cap"" and below $200 million is ""nano cap"".  Worth noting that these boundaries change quite dramatically over time as the overall average market capitalization increases as companies grow, for example in the 80s a company with a market cap of $1 billion would be considered ""large cap"". The market ""determines"" what the market cap of company should be based (usually but certainly not always!) on the historical and expected profit a company makes, for a simple example let's say that our $1000 market cap company makes $100 a year,  this means that this company's earnings per share is $1. If the company grows to make $200 a year you can reasonably expect the share price to rise from $10 to ~$20 with the corresponding increase in market cap. (this is all extremely simplified of course)." "Market caps is just the share price, multiplied by the number of shares. It doesn't represent any value (if people decide to pay more or less for the shares, the market cap goes up or down). It does represent what people think the company is worth.  NAV sounds very much like book value. It basically says ""how much cash would we end up with if we sold everything the company owns, paid back all the debt, and closed down the business? "" Since closing down the business is rarely a good idea, this underestimates the value of the business enormously. Take a hairdresser who owns nothing but a pair of scissors, but has a huge number of repeat customers, charges $200 for a haircut, and makes tons of money every year. The business has a huge value, but NAV = price of one pair of used scissors." Try Google Finance Screener ; you will be able to filter for NASDAQ and NYSE exchanges. I think there is a huge difference to what Google does with intangible assets as compared to a company such as Facebook. Facebook floated and as people thought it was highly overvalued the share price plummeted. Google on the other hand has many years of relatively stable growth and share price in a market that is generally pretty well informed.  So I disagree. "I did a quick search, they have a $2B/5yr deal with google cloud.   Downside is Google is a competitor potentially, especially in the ad market.  Upside is SNAP revenue increased from $58M in 2015 to just over $404M in 2016.  I think in today's market, everyone wants to hold the next ""Amazon"" or ""Google"" stocks at their conception. Sure would be nice if you had a few thousand in Amazon at their IPO. So I think pure speculation is why they were trading above IPO price for so long. It could be the next biggest thing, or it could fail in 5 years we never know these things lol" At this time, Google Finance doesn't support historical return or dividend data, only share prices.  The attributes for mutual funds such as return52 are only available as real-time data, not historical.   Yahoo also does not appear to offer market return data including dividends. For example, the S&P 500 index does not account for dividends--the S&P ^SPXTR index does, but is unavailable through Yahoo Finance. To figure this out, you need to know the price per share then vs the price per share now.  Google Finance will show you historical prices.  For GOOG, the closing price on January 5, 2015 was $513.87.  The price on December 31, 2015 was $758.88.  Return on Investment (ROI) is calculated with this formula: ROI = (Proceeds from Investment - Cost of Investment) / Cost of Investment Using this formula, your return on investment would be 47.7%.  Since the time period was one year, this number is already an annualized return.  If the time period was different than one year, you would normally convert it to an annualized rate of return in order to compare it to other investments. like any share, valuing facebook requires a projection of earnings and earnings growth to arrive at a present value for the right to share in these future earnings.   there are economic arguments to be had for facebook to see either a negative or positive future long term net income growth. given the uncertainty we can establish a very rough baseline value by treating it as a perpetuity (zero growth) discounted at historical equity growth rate (8%) with some very simple math. An annual net income of 900 million discounted at 8 percent in perpetuity is worth 11.25 Billion.  Now, take into account the fact that tech stocks trade at an inflated PE multiple of around 3 times that of a mature company in an established industry (PE x10-20 for average stocks and anywhere between x30-60+ for tech stocks), and I would expect the market cap for this perpetuity to be around 34 Billion.  A market cap of 34 billion is a share value of around 15.5, which is the point where I would take up a long position with fair confidence. I do think that the share deserves a premium for potential income growth (despite the current and potential future revenue losses) simply due to the incredibly large user base and the potential to monetize this. Of course, it wasn't worth the 22 dollar premium that IPO buyers paid but its worth something.  I think there is simply too much uncertainty for me to go long in the next 6 months unless it hits 15/share which may never happen. If the company can monetize mobile and show quarterly results in the next year I would consider a long position for anywhere from 15-20 a share.
