New EU rules aim to protect investors, strengthen markets

New regulations to protect investors, improve market transparency and honesty and prevent another financial crisis went into effect on Wednesday in Europe.

The rules are more than a million paragraphs long, took six years to write and approve, had to be delayed by a year, and despite Wednesday's start date still haven't been passed into national law by more than half the European Union's 28 member states.

The MiFID II rules, bearing a name only a finance professor could love, will have broad impact on how stocks, bonds and investments are traded.
