| Hi Daniel, neat site and I'm really happy someone is taking this on! As the OP noted, the killer feature for me to choose GoogleFinance (GF) above all other "free equities tracking websites" [1] was its portfolio. I've just tried to see if your site addresses those pain points and it doesn't - but I think you're halfway there. What OP's "hypothetical portfolio" means is basically the tracking of a whole set of selected equities (so in your site's case: the performance of everything within a watchlist, including a graph visualizing it plus all the common features like comparing that portfolio-graph to that of the Nasdaq, Dollar Index, BTC ...). [2] GF's UI was horrible, but they allowed to create endless amounts of those portfolios, which was really helpful for finding one's investment strategy because you could compare "ideas". Or you could gather groups of similar equities to track their performance and decide whether they are ripe for becoming "a new idea" (like "I believe that downturn of x is at some point going to halt, maybe then it's worth investing") When GF still had its portfolio feature, I hoped their "re-design" would allow for more mobile-friendliness (which you address) but more importantly comparing portfolio graphs with each other. Also, as non-American I repeatedly ran into trouble finding an equivalent ticker sign for non-US equities [3]. Supporting WKN or ISIN would be an improvement over GF! Anyways, quitting your job for this is a bold step and I wish you the best! [1] Putting that label in quotes maybe highlights the fringeness of that niche and why Google shut it down :-( [2] To be clear: not a graph where i have all the graphs of the items of a watchlist - but one line for all items combined [3] My trouble was usually resolved, finding some European stock's ADR and converting the EUR amount invested to the amount of ADRs i'd have gotten in USD |

I just want to second this point made in the parent comment. What I've always wanted to do that I can't really do in an app out there, is compare my "what-if" scenarios (e.g. what if I had held onto 20% of my AAPL in 2015, instead of selling and buying NFLX and UA/UAA?). I always imagined that there'd be an easy visualization comparison between two scenarios, to allow me to "evaluate" certain buy/sell decisions I've made, retrospectively.
