Transparency has nothing to do with the exchange a stock trades on. Its the company that determines transparency. But I bow to your super knowledge you see I am fairly new to this. I have only been trading stocks for about 55 years, even had a brokers license a while ago. Each exchange has their set of rules and demand certain filings. The toughest is the New York Stock Exchange followed by many others across the world. Don't confuse transparency with filing requirements.
