This was blatant:
"The next day Citigroup's top-rated transport analyst, Jason Smith, failed to publish an expected research report on Patrick, and speculation in the stock became frenzied.
According to a statement of claim filed by ASIC with the Federal Court, one of the most active buyers of Patrick stock was Andrew Manchee, a trader on Citigroup's proprietary trading desk. He bought over one million shares in Patrick. Patrick's price spiked up from $5.70 at the close of business on Thursday, August 18, to $6.45 when the market closed next day.
..... Patrick's stock closed at $8.06 last night. ""
Corrupt as they come.
