Is Yahoo Accurate?

I've been troubled by the reporting structure of the Yahoo Finance section. As described in my previous post, I made a $4000 virtual purchase of a number of stocks on July 1. This 'investment' of some $28,000 currently has a value of $26,596, some $1500 less than one month ago, yet Yahoo reports it as having a $51 increase in value over that period.



As you can see from the above table, my portfolio has not been doing very well, but neither have the markets!

I'll be doing a bit of digging to learn more about Yahoo Finanance in the next while to see if the accuracy can be addressed.

Stay tuned.
