At least now their agents can use it to investigate reports by whistleblowers and others who notice the behavior. No, I do not believe they will actively monitor for suspicious trading patterns and use the database to actually crack down quickly. Government and bureaucracy moves very slow, and is always at least 10 years behind abuses of technology.

Then they can tie the shell company trades to the beneficial owner as well and we will have our own Panama Papers to review.

I love the large volume price swings that happen the day, or days, before news is publicly available. We all know that is insider trading, but SEC rarely does anything about it. Maybe now the will.
