This looks really fun, but I can imagine a few pissed off folks seeing what they missed out on.

Yeah hindsight does really hurt here but not everybody did well. For example check out Zynga http://newinvestordaily.com/what-would-it-be-worth/r/23090

This is fun to play around with.

Can you explain how stock splits are accounted for in the "Percent gain" calculation for this case?: http://newinvestordaily.com/what-would-it-be-worth/r/30991

Intuitively that value would be much larger (300% or so instead of 40%).

Splits and dividends should be factored into the price. I use the adjusted closing price http://www.investopedia.com/terms/a/adjusted_closing_price.a....

However in this case with Ebay it wasn't a stock split but rather a big chunk of Ebay (Paypal) split off into a separate independent company. I think what happened is when Ebay and Paypal separated Ebay share owners gained the equivalent Paypal shares. So this would throw off the numbers.
