Rockwood Holdings, which operates as Rockwood Specialties, gets most of its sales from specialty chemicals, including lithium compounds, metal treatments, and performance additives (such as wood preservation chemicals and iron oxide pigments). Other products include titanium dioxide, advanced ceramics, specialty compounds, and custom synthesis intermediates. It serves the construction, paper, and water treatment industries. A leader or #2 in many of its niches, the firm was created in 2000 when Kohlberg Kravis Roberts (KKR) bought several Laporte divisions; it got much larger by adding parts of Dynamit Nobel in 2004. Sales to Germany outpace those to any other nation. KKR owns almost a third of Rockwood.

A technical indicator that measures the percentage change between the most recent price and the price "n" periods in the past. It is calculated by using the following formula:

(Closing Price Today - Closing Price "n" Periods Ago) / Closing Price "n" Periods Ago

ROC is classed as a price momentum indicator or a velocity indicator because it measures the rate of change or the strength of momentum of change.

Investopedia Says:
Many traders use a value greater than zero to indicate an increase in upward momentum and a value less than zero to indicate an increase in selling pressure. However, some of the most valuable signals are generated when the price of the asset and the ROC are heading in opposite directions (known as divergence). For example, in the chart above you can see that the ROC is sloping downward while the price of the asset is increasing. This is generally an early indication that a sharp decline may be on the way.
