I keep seeing stories about inventory rebuilding having contributed sinificantly to Q3 US GDP. When I saw the preliminary breakdown, it was clear that it was not the most significant contributor; now the Q3 Flow of Funds report appears to show continued reduction of inventories (report here; see page 15 (22 of the PDF), section F.8, line 26).

Does anybody know what is going on? Is it just that the inventory rebuild idea has taken hold?
