Rises and falls
We were finally seeing some rising values again recently, but have again hit a decline cycle. Some badly timed reindexing and issues with the spiders being down has caused a downward spiral, as the declining values caused blogs that would have received gains to lose value. A change in the reindex order may have resulted in gains all around...
This is one important reason why it is important to use the Stock Broker feature for blogs you own shares in, or do some quick calculations for blogs you don't own shares in.
One quick way that I do this to see if a blog will gain or lose is to just add up the millions and hundred-thousands with a calculator and see if this comes out as higher than the current blog value. To get a bit more accuracy for small increases, I may round down to the thousands place (ex, an incoming blog with a value of B$ 1,218,168.92 I'd enter into the calculator as 1218). A small gain would be enough to warrant a reindex.
Blogs that feed into each other should have the blog with the highest increase indexed first for maximum benefit, buy if you aren't using the Stock Broker, that's hard to determine, but any positive trend is a good thing. Don't reindex blogs that are to be losers, let them keep the higher value until other incoming blogs catch up.
