The latest CFTC Commitment of Traders Report that came out Monday afternoon after 3:30 p.m. showed that the short position in silver contracted very slightly, from 54, 811 contracts to 52, 398 contracts.
However, Dr. Goldacre takes a slightly different position a bit later in the book (Bad Pharma, p. 243) in a section where he chastises the National Health Service (NHS) in the UK for wasting money by not using generics.
