Search index futures in Yahoo Finance or Google Finance
Options - yes we can :) Options tickers on Yahoo! Finance will be displayed as per new options   symbology announced by OCC. The basic parts of new option symbol are: Root symbol + Expiration   Year(yy)+ Expiration Month(mm)+ Expiration Day(dd) + Call/Put   Indicator (C or P) + Strike price Ex.: AAPL January 19 2013, Put 615 would be AAPL130119P00615000 http://finance.yahoo.com/q?s=AAPL130119P00615000&ql=1 Futures - yes as well (: Ex.: 6A.M12.E would be 6AM12.CME using Yahoo Finance symbology. (simple as that, try it out) Get your major futures symbols from here: http://quotes.ino.com/exchanges/exchange.html?e=CME Neither site offers index futures or options pricing.  Your best best is likely to get the quote from a broker who supports trading those vehicles. Free sites usually limit themselves to stocks and sometimes to options chains -- the exception is Reuters where just about any security for which you have the reuters formatted trading symbol can be quoted. Yahoo finance does in fact have futures quotes.  But I've found them difficult to search for because you also have to know the expiration codes for the contract to find them. S&P 500 Emini quote for June 2012
"Good observation. In fact, the S&P index itself is guilty of not including dividends. So when you look at the index alone, the delta between any two points in time diverges, and the 20 return observed if one fails to include dividends is meaningless, in my my humble opinion. Yahoo finance will let you look at a stock ticker and offer you an ""adjusted close"" to include the dividend effect." Over the past five years, QFVOX has returned 13.67%, compared to the index fund SPY that has returned 50.39%. SEVAX has lost 23.96%. AKREX has returned 81.82%. In two of your three examples, you would have done much better in an index fund with a very low expense ratio as suggested. While one can never, as you see, make a generalization, in almost every case, most investors will do better, and often much better, with an index fund with a low expense ratio. My source was Google Finance. A few days ago they launched Fannie Mae Guaranteed Multifamily Structures (link) but who knows?  It's a penny stock now. Google Finance is pretty good at marking news right on the chart for a particular stock.  That's how I tracked that piece of news down.  Can't say that it precipitated a lot of people buying the stock, but Google Finance isn't a bad place to start looking. The difference is that Yahoo is showing the unadjusted price that the security traded for on that date, while google is adjusting for price splits. This means that Google is showing how much you would have had to pay to get what is now one share. Since 1979, JNJ has split 3-for-1 once, and 2-for-1 four times. 3x2x2x2x2 = 48. If you bought 1 share at that time, you would now have 48 shares today. Yahoo is showing a price of $66 for what was then 1 share. $66/48 = 1.375, which Google rounds to 1.38. You can see this if you get the prices from May 14-21, 1981. The stock split 3-for-1, and the price dropped from 108 to 36.38. Yahoo's adjusted close column has not been accurate since they re-wrote the Finance website. It now just represents the closing price. The other relevant field on Yahoo is the Adj. Close. This adjusts for splits, but also adjusts for dividends. Hence why this doesn't match either the Google or Yahoo numbers. The other answer covers the mechanics of how to buy/sell a future contract. You seem however to be under the impression that you can buy the contract at 1,581.90 today and sell at 1,588.85 on expiry date if the index does not move. This is true but there are two important caveats: In other words, it is not the case that your chance of making money by buying that contract is more than 50%... I think Infochimps has what you are looking for: NYSE and NASDAQ. You can trade an index by using a Contract For Difference, or CFD. Various brokers offer this method and the spreads are quite low. They tend to widen outside of market hours, and not all brokers offer the same spreads. I would look for a broker that offers the lowest spread on the index you are interested in. You should also do your due diligence and check they are regulated by the relevant authority  pertaining to their territory, eg FSA for uk On closer look, it appears that Google Finance relies on the last released 10-k statement (filing date 10/30/2013), but outstanding shares as of last 10-Q statement. Using these forms, you get ($37,037M / 5.989B ) = $6.18 EPS. I think this is good to note, as you can manually calculate a more up to date EPS value than what the majority of investors out there are relying on.
