I would get your company to do a trial of edgar onlines “I-Metrix”. It works right in MS excel and fetches historical data that is most accurate and places it right into spreadsheets using XBRL. there are great templates too.

the new version works with vista and office 2007. check it out.

NYSE.com, cnnfn.com and marketwatch.com all say 33 wk high. Y! Finance is the outlier here. My guess is that it represents 52-wk intraday high. Which is what I think most people use, I’ve never heard of someone only looking at 52-wk closing high/lows. I’m Canadian, but haven’t traded TSX in a while.

Thanks for posting here Matthew. Definitely appreciate it!

I did some more investigation. March 24th, 2006 is the first day of trading for THI. However, Yahoo does not have data for that particular day. As well I found this snippet from a Canadian news story:

“Shares peaked at $37.99 in frenzied trading and wound up the day on the Toronto Stock Exchange at $33.10,”

http://www.ctv.ca/servlet/ArticleNews/story/CTVNews/20060324/tim_hortons_onsale_060324/20060324

Using currency exchange rates, THI on the NYSE could not have closed anywhere near $33 USD. But it could mean there were intra-day highs achieved throughout the day.

One of my pet peeves is that you’re not making clear if the 52-wk high is intra-day figures or based on closing figures. You really gotta decide one way or the other. Your charts representing the figures at market close, so you shouldn’t be displaying data contrary to that assumption without some form of notification.

We’re aware that there are some data inaccuracies on the Google Finance site, and we’re working to fix them where and as we find them. Alas, the job of processing and merging the various financial data sources isn’t as straightforward as one might hope.

In the specific case of NYSE:THI, though, I don’t think we’re in the wrong, or if we are, we’ve got prestigious company. NYSE.com reports the 52-week high as being $33.00, set on March 24, 2006. A glance at our own records shows a trade of 100 shares at 9:46:07 for $33.00. I’d point this out to you on our charts, but embarassingly enough, we’re only rendering back to March 27th. I’ll look into that.

Bzzzt! Yahoo looks wrong here. NYSE reports THI 52wk high as 33, and so does cnnfn:

(as a Canadian I’m morally obligated to track Timmy’s.)
