I look at the market message rather than who bought what when.  And the market verdict for December is unabashedly bullish.  

In a terrible month for equities worldwide, RVX finished down only 1%.  That is truly awesome.  For comparison, the MSCI World Healthcare index returned -8% in December, the MSCI World Biotech index gave -6%, MSCI USA Healthcare index -8.8%.  

Now the interesting thing is that these are almost the same returns for the last quarter as well...but RVX did -8.6%.  So RVX is now pulling ahead slowly but surely from its Biotech and Healthcare peers.  

The only negative is that without today's action, RVX would not look so good.  We would be in line with the Biotech/Healthcare indices for December.  But hey...the end score is what counts!
