I hear what you say but I have known of at least one broker/bank that in the USA had to pay hundreds of millions in compensation for doing the same thing. Time it was tested in OZ. Our laws are supposed to be tighter than the US they just need to be applied. Think about it the broking arm of a very large institution issues a document specifying a company has top management and a huge valuation and recommends it as a top pick whereas its banking arm that owns huge numbers of shares is instructing its brokers , probably the in house broker to dump just before the poop hits. It would also be interesting if the same banker was one of the lenders to the company and would have intimate knowledge of the financial position.
