Where can I find historical ratios of international stock indexes?
I found a possible data source. It offers fundamentals i.e. the accounting ratios you listed (P/E, dividend yield, price/book) for international stock indexes. International equity indices based on EAFE definitions are  maintained by Professor French of French-Fama fame, at Dartmouth's Tuck Business School website. Specifics of methodology, and countries covered is available here. MSCI is the data source. Historical time interval for most countries is from 1975 onward. (Singapore was one of the countries included). Obtaining historical ratios for international stock indices is not easily found for free. Your question didn't specify free though. If that is not a constraint, you may wish to check the MSCI Barra international stock indices also.
As stated in the comments, Index Funds are the way to go. Stocks have the best return on investment, if you can stomach the volatility, and the diversification index funds bring you is unbeatable, while keeping costs low.  You don't need an Individual Savings Account (UK), 401(k) (US) or similar, though they would be helpful to boost investment performance. These are tax advantaged accounts; without them you will have to pay taxes on your investment gains. However, there's still a lot to gain from investing, specially if the alternative is to place them in the vault or similar. Bear in mind that inflation makes your money shrink in real terms. Even a small interest is better than no interest.  By best I mean that is safe (regulated by the financial authorities, so your money is safe and insured up to a certain amount) and has reasonable fees (keeping costs low is a must in any scenario).  The two main concerns when designing your portfolio are diversification and low TER (Total Expense Ratio). As when we chose broker, our concern is to be as safe as we possibly can (diversification helps with this) and to keep costs at the bare minimum.  Some issues might restrict your election or make others seem better. Depending on the country you live and the one of the fund, you might have to pay more taxes on gains/dividends. e.g. The US keeps some of them if your country doesn't have a special treaty with them. Look for W-8Ben and tax withholding for more information.  Vanguard and Blackrock offer nice index funds. Morningstar might be a good place for gathering information. Don't trust blindly the 'rating'. Some values are 'not rated' and kick ass the 4 star ones. Again: seek low TER. Not a big fan of this point, but I'm bound to mention it. It can be actually helpful for sorting out tax related issues, which might decide the kind of index fund you pick, and if you find this topic somewhat daunting. You start with a good chunk of money, so it might make even more sense in your scenario to hire someone knowledgeable and trustworthy. I hope this helps to get you started. Best of luck. "If you want the answer from the horse's mouth, go to the website of the ETF or mutual find, and the expense ratio will be listed there, both on the ""Important Information"" part of the front page, as well as in the .pdf file that you click on to download the Prospectus.  Oh wait, you don't want to go the fund's website at all, just to a query site where you type in something like VFINX. hit SEARCH, and out pops the expense ratio for the Vanguard S&P 500 Index Fund? Well, have you considered MorningStar?" The Investopedia article you linked to is a good start. Its key takeaway is that you should always consider risk-adjusted return when evaluating your portfolio. In general, investors seeking a higher level of return must face a higher likelihood of taking a loss (risk). Different types of stocks (large vs small; international vs US; different industry sectors) have different levels of historical risk and return. Not to mention stocks vs bonds or other financial instruments... So, it's key to make an apples-to-apples comparison against an appropriate benchmark. A benchmark will tell you how your portfolio is doing versus a comparable portfolio. An index, such as the S&P 500, is often used, because it tells you how your portfolio is doing compared against simply passively investing in a diversified basket of securities. First, I would start with analyzing your portfolio to understand its asset allocation. You can use a tool like the Morningstar X-Ray to do this. You may be happy with the asset allocation, or this tool may inform you to adjust your portfolio to meet your long-term goals. The next step will be to choose a benchmark. Given that you are investing primarily in non-US securities, you may want to pick a globally diversified index such as the Dow Jones Global Index. Depending on the region and stock characteristics you are investing in, you may want to pick a more specialized index, such as the ones listed here in this WSJ list. With your benchmark set, you can then see how your portfolio's returns compare to the index over time. IRR and ROI are helpful metrics in general, especially for corporate finance, but the comparison-based approach gives you a better picture of your portfolio's performance. You can still calculate your personal IRR, and make sure to include factors such as tax treatment and investment expenses that may not be fully reflected by just looking at benchmarks. Also, you can calculate the metrics listed in the Investopedia article, such as the Sharpe ratio, to give you another view on the risk-adjusted return. No, some of Vanguard's funds are index funds like their Total Stock Market Index and 500 Index. In contrast, there are funds like Vanguard PRIMECAP and Vanguard Wellington that are actively managed. There are index funds in both open-end and exchange-traded formats. VTI is the ticker for Vanguard's Total Stock Market ETF while VTSMX is an open-end mutual fund format. VOO would be the S & P 500 ETF ticker while VFINX is one of the open-end mutual fund tickers, where VIIIX has a really low expense ratio but a pretty stiff minimum to my mind. As a general note, open-end mutual funds will generally have a 5 letter ticker ending in X while an ETF will generally be shorter at 3 or 4 letters in length. In order to see whether you can buy or sell some given quantity of a stock at the current bid price, you need a counterparty (a buyer) who is willing to buy the number of stocks you are wishing to offload. To see whether such a counterparty exists, you can look at the stock's order book, or level two feed. The order book shows all the people who have placed buy or sell orders, the price they are willing to pay, and the quantity they demand at that price. Here is the order book from earlier this morning for the British pharmaceutical company, GlaxoSmithKline PLC.  Let's start by looking at the left-hand blue part of the book, beneath the yellow strip. This is called the Buy side. The book is sorted with the highest price at the top, because this is the best price that a seller can presently obtain. If several buyers bid at the same price, then the oldest entry on the book takes precedence. You can see we have five buyers each willing to pay 1543.0 p (that's 1543 British pence, or £15.43) per share. Therefore the current bid price for this instrument is 1543.0. The first buyer wants 175 shares, the next, 300, and so on. The total volume that is demanded at 1543.0p is 2435 shares. This information is summarized on the yellow strip: 5 buyers, total volume of 2435, at 1543.0. These are all buyers who want to buy right now and the exchange will make the trade happen immediately if you put in a sell order for 1543.0 p or less. If you want to sell 2435 shares or fewer, you are good to go. The important thing to note is that once you sell these bidders a total of 2435 shares, then their orders are fulfilled and they will be removed from the order book. At this point, the next bidder is promoted up the book; but his price is 1542.5, 0.5 p lower than before. Absent any further changes to the order book, the bid price will decrease to 1542.5 p. This makes sense because you are selling a lot of shares so you'd expect the market price to be depressed. This information will be disseminated to the level one feed and the level one graph of the stock price will be updated. Thus if you have more than 2435 shares to sell, you cannot expect to execute your order at the bid price in one go. Of course, the more shares you are trying to get rid of, the further down the buy side you will have to go. In reality for a highly liquid stock as this, the order book receives many amendments per second and it is unlikely that your trade would make much difference. On the right hand side of the display you can see the recent trades: these are the times the trades were done (or notified to the exchange), the price of the trade, the volume and the trade type (AT means automatic trade).  GlaxoSmithKline is a highly liquid stock with many willing buyers and sellers. But some stocks are less liquid. In order to enable traders to find a counterparty at short notice, exchanges often require less liquid stocks to have market makers. A market maker places buy and sell orders simultaneously, with a spread between the two prices so that they can profit from each transaction. For instance Diurnal Group PLC has had no trades today and no quotes. It has a more complicated order book, enabling both ordinary buyers and sellers to list if they wish, but market makers are separated out at the top. Here you can see that three market makers are providing liquidity on this stock, Peel Hunt (PEEL), Numis (NUMS) and Winterflood (WINS). They have a very unpalatable spread of over 5% between their bid and offer prices. Further in each case the sum total that they are willing to trade is 3000 shares. If you have more than three thousand Dirunal Group shares to sell, you would have to wait for the market makers to come back with a new quote after you'd sold the first 3000. You better buy an ETF that does the same, because it would be much cheaper than mutual fund (and probably much cheaper than doing it yourself and rebalancing to keep up with the index).  Look at DIA for example. Neither buying the same amount of stocks nor buying for the same amount of money would be tracking the DJIE. The proportions are based on the market valuation of each of the companies in the index. As @littleadv and @DumbCoder point out in their comments above, Bloomberg Terminal is expensive for individual investors.  If you are looking for a free solution I would recommend Yahoo and Google Finance. On the other side, if you need more financial metrics regarding historic statements and consensus estimates, you should look at the iPad solution from Worldcap, which is not free, but significantly cheaper then Bloomberg and Reuters. Disclosure: I am affiliated with WorldCap. I don't see it in any of the exchange feeds I've gone through, including the SIPs. Not sure if there's something wrong with Nasdaq Last Sale (I don't have that feed) but it should be putting out the exact same data as ITCH.
