My grandfather bought some stock in a paper company (consolidated Water Power and Paper Company) around 1912. I was given some of the stock around 1985. When I sold the stock in 2010, the basis was less than zero. This essentially means that they paid me to take the stock. Therefore you can't figure a percentage profit since it is infinite.
The point is that your question is not specific enough.
I have invested in more than 50 dividend stocks in U.S and Canada. My biggest was Canadian Utilities (TSX: CU), returned around 60% so far. I invest in income generating stocks for long-term. See my personal portfolio here:http://www.financejourney.com/my-dividen...
Hope this help.
My biggest was Apple, returned around 500%. Had others that returned 100% to 200%. Also had some major losers too though.
Just want to know a little more about the stock market
