Many members within this community show that they own USG stock.  From my own research, I have found that USG is owned by many value investment firms/funds and also by that one guy with the last name Buffett.  I am a huge advocate of insider buying.

Well for the people who were interested in purchasing or have already purchased USG, then the most recent news in insider activity would be very beneficial to your investment decision. 

A company by the name of

GEBR. KNAUF VERWALTUNGSGESELLSCHAFT KG .

has been purchasing shares of USG around $36.  They now own approximately 11% of the company.  After further research, this group is a global supplier of building materials.  Visit www.knauf.com for more information.  Maybe they saw tremendous value in USG just like the rest of the value investing world.

OR maybe they want to buy out the company outright?!?!  We shall wait and see what transpires...
