What is the 'Information Ratio - IR'. The information ratio (IR) is a ratio of portfolio returns above the returns of a benchmark -- usually an index -- to the volatility of those returns. The information ratio (IR) measures a portfolio manager's ability to generate excess returns relative to a benchmark but also attempts to identify the consistency of the investor.
Prop 65 lists of over 900 substances, including lead, that businesses are required to warn consumers about. Lead is a natural element in soil, so it can be found in trace amounts in anything that is grown or drawn from the earth â including fruits, vegetables, and, of course, Earthpaste.
One Natural News reader forwarded me a message from a zeolite company who claims their product has no lead in it because there were assured it was 100% pure. This is, of course, complete nonsense. All zeolites contain lead and aluminum. There's no such thing as a lead-free, aluminum-free zeolite, especially since zeolites are made of aluminum.
