In this installment I’m going to take a look at what the big web portals have to offer. But first I want to review how returns are calculated and what you should be looking for from those numbers.
Calculating Your Returns
There’s a lot of ways to calculate your returns, but unfortunately all these web sites use the simplest of methods: Total Return. Basically, they compare the ratio of your gains (or losses) to your costs without taking time into account. This is fine if you bought all your investments in one shot (at least on the same day) and now you’re going to sit back and watch them, that’s not the case for those who have gotten Zebra Loans to invest in smaller portions. Well there are some brokers which are making offers which are really good from investment point of view.
Pass the popcorn!
In reality you want to know your annualized return. Which is a fancy way to say you want to your average annual return. Except it’s not as easy as dividing the Total Return by the number of years you’re invested (that would be the simple or arithmetic average – and it’s the wrong way to annualize your returns). A better way would be to calculate your geometric average or compound return.
But there are even better ways: Money-Weighted or Internal Rate of Return, Time-Weighted or Linked Internal Rate of Return, Modified Dietz Rate of Return, or the Daily Valuation Method. The best would be the Daily Valuation Method, but unless you have a super-computer you won’t be calculating this one.
Of all these probably the best compromise between efficiency and accuracy is the Modified Dietz Method (also known as Approximate Time-Weighted Rate of Return). Once you’ve calculated that for each period (monthly, quarterly, or annually) you can link it together geometrically to see your annualized return over the years.
Once you know your annualized rate of return you can properly compare your investments and see which ones really are doing well, and which ones just sound good.
Now hopefully one of these web sites, at least the ones that track dividends, take all that information to calculate a proper annualized rate of return.
These are the big internet sites where a lot of us start our day. They bring a lot together, like news and weather, functionality like web searches, e-mail and calendars, and more. Adding a portfolio to that isn’t a stretch but since it’s not their focus we might not expect anything exciting from them, but we hope that with everything else going there’s going to be some interesting integration – like easy searches, e-mail alerts, and social sharing.
They nailed the user experience with a clean and simple design that puts more data onto one page than any other site, and there’s even a gadget for my iGoogle home page and functions for my Google
DocsDrive Spreadsheets. The charts are perfection: I could configure my own default settings and with one click I could expand the chart to the full width of my screen. But they blew it on data since dividend information for Canadian stocks (ETF’s in particular) is sometimes missing, in-complete, or just plain wrong!
They have one of the nicest portfolios – it’s actually a Silverlight app so it better be slick! But the rest is held together with duct tape and bubble gum. And basic information for Canadian stocks – even blue chip stocks – is frequently missing. The initially beautiful web site falls apart just below surface.
This is what you’d expect from a web-base portfolio. It looks nice, but the functionality is pretty basic and regrettably dividend information is often missing for Canadian stocks and the news is U.S. focused. Since Yahoo has fallen on hard times they’re probably not putting a lot of effort into something you can get everywhere else, so unfortunately I have to recommend you go somewhere else!
In the next installment I’ll take a look at what the news outlets have to offer. While some are astounding there are a few stinkers in the bunch!
