"In the US there is only one stock market (ignoring penny stocks) and handfuls of different exchanges behind it.  NYSE and NASDAQ are two different exchanges, but all the products you can buy on one can also be bought on the other; i.e. they are all the same market.  So a US equities broker cannot possibly restrict access to any ""markets"" in the US because there is only one. (Interestingly, it is commonplace for US equity brokers to cheat their customers by using only exchanges where they -- the brokers -- get the best deals, even if it means your order is not executed as quickly or cheaply as possible.  This is called payment for order flow and unfortunately will probably take an Act of Congress to stop.) Some very large brokers will have trading access to popular equity markets in other countries (Toronto Stock Exchange, Mexico Stock Exchange, London Stock Exchange) and can support your trades there.  However, at many brokers or in less popular foreign markets this is usually not the case; to trade in the average foreign country you typically must open an account with a broker in that country." 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! Oh hey, let's take an insane valuation from the peak of the tech bubble and act like it should be a useful metric. Exxon has a market cap around 430 billion, Apple is just under 600 billion.    Microsoft was never making enough nor looked like it could sustain enough growth to support a 600b market cap.  Don't be stupid.  The stock was grossly overvalued as everything was then. 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. "It's tough to share exactly what happened. Go to yahoo and look at the chart for Cisco from 1990 to 2003 or so. From a split adjusted 8 cents a share, it peaked at just under $80 in March 2000, up by a factor of 1000. People were buying in thinking this stock would continue to rise at this pace, but logic says that's preposterous. By April of 2001, it was down to $14, 80% off its high, and later to drop below $10.  This was a classic bubble and should be studied so you don't get caught in them. A book titled Extraordinary Popular Delusions & the Madness of Crowds was published in 1841, yes is still an interesting read. Bubbles in markets are not new, but can be recognized and avoided. Cisco at $80 had a market cap of $438B. Had it risen 1000 fold over another decade, it would have been worth $438T, but all the wealth in the US isn't even $75T, so something was wrong, very wrong. This is one story, one stock. A remarkable time.  Yes, many companies went under, and the employees lost their jobs. And those who were heavy into the ""dotcom"" stocks lost as much as 80% (or more) of their wealth. Entire 401(k) accounts dropping this amount due to bad decisions. Those who bailed out in time survived, some doing better than others." Obviously, these numbers can never be absolute simply because not all the information is public. Any statistic will most likely be biased. I can tell you the following from my own experience that might get you closer in your answer: Hence, even though I cannot give you exact numbers, I fully agree that traders cannot beat the index long term. If you add the invested time and effort that is necessary to follow an active strategy, then the equation looks even worse.  Mind you, active trading and active asset allocation (AAA) are two very different things. AAA can have a significant impact on your portfolio performance. Stock A last traded at $100. Stock A has 1 million shares outstanding. No seller is willing to sell Stock A for less than $110 a share. One buyer is willing to buy 1 share for $110. The order executes. The buyer pays the seller $110. Stock A's new price is $110. An $110 investment increased the market cap by $10 million. Neat trick (for all who own Stock A). One year is short term -- short enough that trying to predict returns is a crap shoot. Frankly, if you will need the money in one year I wouldn't touch anything riskier than a money market account. $5000 also isn't enough to give you much flexibility in achieving a balanced portfolio, since the minimal initial purchase for mutual funds is often around $2500. (I'm not sure whether ETFs would give you any more flexibility.) So on grounds of both size and time horizon, I have to recommend against this plan. The risk of losing money, with insufficient time for gains to balance that risk, is simply too high. Others may feel differently, of course. But that's the best advice I can offer.
