Why does historical price data not go back all the way on Google Finance?
Google Finance and Yahoo Finance have been transitioning their API (data interface) over the last 3 months. They are currently unreliable. If you're just interested in historical price data, I would recommend either Quandl or Tiingo (I am not affiliated with either, but I use them as data sources). Both have the same historical data (open, close, high, low, dividends, etc.) on a daily closing for thousands of Ticker symbols. Each service requires you to register and get a unique token. For basic historical data, there is no charge. I've been using both for many months and the data quality has been excellent and API (at least for python) is very easy! If you have an inclination for python software development, you can read about the drama with Google and Yahoo finance at the pandas-datareader group at https://github.com/pydata/pandas-datareader.
"Google Finance certainly has data for Tokyo Stock Exchange (called TYO on Google) listings.  You could create a ""portfolio"" consisting of the stocks you care about and then visit it once per day (or write a script to do so)." Yes, past option prices are available for many options, but as far as I know not for free.  You can get them from, for example, OptionMetrics.  Probably there are other providers as well, which may be cheaper for an individual or small institution. OptionMetrics data comes from the National Best Bid and Offer.  Probably there are some over-the-counter options that are not included here, but for someone asking this question, OptionMetrics will most likely have the option you are interested in. "The tricky part is that it's NAV is quite high these days, almost close to its 52 week high You will find, if you look historically, most markets are often close to their 52 week or even historical highs. This is an important consideration. ""The markets are at their all-time high!"" has been true a large percentage of the past decades. Everyone wants to buy low, sell high. But the reality is, buying low often will be ""buying at close to the highest point"" as no one has a crystal ball." Interactive Brokers provides historical intraday data including Bid, Ask, Last Trade and Volume for the majority of stocks. You can chart the data, download it to Excel or use it in your own application through their API.  EDIT: Compared to other solutions (like FreeStockCharts.com for instance), Interactive Brokers provides not only historic intraday LAST**** trades **but also historic BID and ASK data, which is very useful information if you want to design your own trading system.  I have enclosed a screenshot to the chart parameter window and a link to the API description. This is from Google Finance right now. Well your gripe is using historic data to estimate VAR. That is separate topic. Either way however something that happens twice a century cant be considered an outlier and if you choose to use historic data then such things need to be included. I've had luck finding old stock information in the Google scanned newspaper archives. Unfortunately there does not appear to be a way to search exactly by date, but a little browsing /experimenting should get what you want. For instance, here's a source which shows the price to be 36 3/4 (as far as I can read anyway) on that date. even in Bloomberg intraday data you're limited to 140days. If you want more you need cash, a lot of cash. Just the sheer size of data is ridiculous. Unless you're Blackrock or some big firms like that then probably can't afford to buy it and store it - it won't fit on one Excel file haha "I had  both closing price and adjusted price of Apple showing the same amount after ""download data"" csv file was opened in excel. https://finance.yahoo.com/quote/AAPL/history?period1=1463599361&period2=1495135361&interval=div%7Csplit&filter=split&frequency=1d Its frustrating. My last option was to get the dividends history of the stock and add back to the adjusted price to compute the total return for a select stock for the period." I also searched for some time before discovering Market Archive, which AFAIK is the most affordable option that basically gives you a massive multi-GB dump of data.  I needed sufficient data to build a model and didn't want to work through an API or have to hand-pick the securities to train from.  After trying to do this on my own by scraping Yahoo and using the various known tools, I decided my time was better spent not dealing with rate-limiting issues and parsing quirks and whatnot, so I just subscribed to Market Archive (they update the data daily). Goldprice.org has different currencies and historical data. I think silverprice.org also has historical data. I am mostly interested in day to day records, and would like the data to contain information such as dividend payouts, and other parameters commonly available, such as on : http://finviz.com/screener.ashx ... but the kind of queries you can do is limited. For instance you can only go back two years. This is just a shot in the dark but it could be intermarket data. If the stock is interlisted and traded on another market exchange that day then the Yahoo Finance data feed might have picked up the data from another market. You'd have to ask Yahoo to explain and they'd have to check their data. The point of that question is to test if the user can connect shares and stock price.  However, that being said yeah, you're right. Probably gives off the impression that it's a bit elementary. I'll look into changing it asap. "Such data is typically only available from paid sources due to the amount of research involved in determining the identity of delisted securities, surviving entities in merger scenarios, company name changes, symbol changes, listing venue changes, research of all capital events such as splits, and to ensure that the data coverage is complete. Many stocks that are delisted from a major exchange due to financial difficulties are still publicly tradeable companies with their continuing to trade as ""OTC"" shares.  Some large companies even have periods where they traded for a period of their history as OTC.  This happened to NYSE:NAV (Navistar) from Feb 2007 to July 2008, where they were delisted due to accounting statement inaccuracies and auditor difficulties.   In the case of Macromedia, it was listed on NASDAQ 13 Dec 1993 and had its final day of trading on 2 Dec 2005.  It had one stock split (2:1) with ex-date of 16 Oct 1995 and no dividends were ever paid. Other companies are harder to find.  For example, the bankrupt General Motors (was NYSE:GM) became Motoros Liquidation Corp (OTC:MTLQQ) and traded that way for almost 21 months before finally delisting. In mergers, there are in two (or more) entities - one surviving entity and one (or more) delisted entity.  In demergers/spinoffs there are two (or more)  entities - one that continues the capital structure of the original company and the other newly formed spun-off entity.  Just using the names of the companies is no indication of its history. For example, due to monopoly considerations, AT&T were forced to spinoff multiple companies in 1984 and effectively became 75% smaller.  One of the companies they spunoff was Southwestern Bell Corporation, which became SBC Communications in 1995.  In 2005 SBC took over its former parent company and immediately changed its name to AT&T.  So now we have two AT&Ts - one that was delisted in 2005 and another that exists to this day.
