Some of the features I like most about Google Finance are:
- Stock charts in Flash are quick, interactive, and great for looking at comparisons between companies and time frames. They also mark dividend payments right on the chart which I really like for quickly looking at dividend growth or dividend history without much digging. Volume seems to be very obvious when compared with other sources as well.
- Relevant news stories are sorted chronologically for your stocks, as well as general stories; also company events, and a link to investor relations are right there on the company page which has very much a 'one stop shop' approach to everything.
- A 'Historical Prices' link can quickly show you volume and prices on any trading day.
- The field where you type your symbol or company name and it automatically fills in is extremely quick and handy.
Recent additions include video, the ability to create a portfolio, top movers, market cap, popularity, and many more.
Some areas that Google needs to work on, (and I'm sure they are) are more on the financial and fundamental end. The site is certainly not my first choice for analyzing a company's key ratios, or financials.
Just like several other products from Google, 'Finance' is quick, very user friendly, and intuitive. I look forward to seeing more upgrades and changes as time goes on. I am expecting big things, as some of Google's other sites like 'Maps' and 'Earth' are nothing short of amazing. I would encourage anyone who has not checked this site out to go on and run a few charts and compare a few companies. You never know, you might get hooked like me.
