Back in when CDs ruled the music world, artists worked out the Soundscan scam. All CDs came out on Tuesdays. Artists recruited street teams in multiple cities to go to a handful of record stores and buy a few copies of their CD on its debut Tuesday. The music sales metric vendor called Soundscan would pick up these sales numbers and deliver them overnight to the labels. On Wednesday the labels' marketing teams would take a look at the numbers and interpret them as widespread interest. So they would back the CD with marketing programs, giving the CD a better chance to find an audience. Similar things happen with book sales. But, the point here is to find an audience, not to manipulate the stock market.
