Retrieving stock quotes using concatenate

Question

I've read most of the posts on downloading stock quotes and I haven't quite found the answer to my question, so here goes a new discussion...
I have a table of 57 ticker symbols that I follow. The table grows and shrinks regularly as I find new companies to follow and remove ones that don't meet my needs. Each ticker symbol is listed in column A of my DATA table and each row contains all the various data for that symbol. Here's a small section of that table as an example...

I've created a CONCATENATE formula to combine the ticker symbols into a single cell (C12):
=CONCATENATE(Data :: A3,",",Data :: A4,",",Data :: A5,",",Data :: A6,",",Data :: A7,",",Data :: A8,",",Data :: A9,",",Data :: A10,",",Data :: A11,",",Data :: A12,",",Data :: A13,",",Data :: A14,",",Data :: A15,",",Data :: A16,",",Data :: A17,",",Data :: A18,",",Data :: A19,",",Data :: A20,",",Data :: A21,",",Data :: A22,",",Data :: A23,",",Data :: A24,",",Data :: A25,",",Data :: A26,",",Data :: A27,",",Data :: A28,",",Data :: A29,",",Data :: A30,",",Data :: A31,",",Data :: A32,",",Data :: A33,",",Data :: A34,",",Data :: A35,",",Data :: A36,",",Data :: A37,",",Data :: A38,",",Data :: A39,",",Data :: A40,",",Data :: A41,",",Data :: A42,",",Data :: A43,",",Data :: A44,",",Data :: A45,",",Data :: A46,",",Data :: A47,",",Data :: A48,",",Data :: A49,",",Data :: A50,",",Data :: A51,",",Data :: A52,",",Data :: A53,",",Data :: A54,",",Data :: A55,",",Data :: A56,",",Data :: A57,",",Data :: A58,",",Data :: A59)
Returns to cell C12 the following:
AAPL,ACN,AFL ...  WMT,YUM
I then use the next formula to retrieve updated quotes from the Yahoo website:
=HYPERLINK("http://finance.yahoo.com/d/quotes.csv?s=" & C12 & "&f=snl1d1","Download Prices")
Once the quotes.csv is downloaded, I copy and past the stock prices into my Data table.
Now to my question:
Can the CONCATENATE formula above be simplified so that it's easier to add or remove cells?
If I add a bunch of new symbols to the Data table then I have to remember to add each new cell to the formula above. Or, if I delete a bunch of symbols then I delete the same number of cells from the formula.
This is a great example of the need for a range of cells in CONCATENATE.
Perhaps some programmer can get create and allow =CONCATENATE(Data :: A3:A59,",") where A3:A59 is the range and "," indicates an optional separation character.

Answer 1

You can implement like:
The top table is name "Download Link" and is a single-cell table.  The bottom table contains your ticker symbols and has a column which concatentates the previous list with a new sysmbol-- you can hide column B.
B2=B1&IF(ISBLANK(A2), "", IF(ROW() = 2, "", ",")&A2)
select B2 and fill down as needed.
In the top table "Download Link"
A1=HYPERLINK("http://finance.yahoo.com/d/quotes.csv?s=" & OFFSET(TickerTable :: $B$2, ROWS(TickerTable :: B)-2, 0) & "&f=snl1d1","Download Prices")
This takes the fully concatenated string from column B of the ticker table.  If you change the name of the tables adjust them in the formulas.
