Housing Bubble or Not

Today I noted with great interest that CALPERS has decided that it's time to "cash in on real estate profits". They are liquidating 207 industrial buildings, 97 shopping centers and 22 office properties. We're talking some massive selling. The other side of the coin is that all of the property is being gobbled up by investors dying to get into real estate. Now this doesn't having anything to do with housing but it is an interesting occurrence.
