Problem: Article: All companies make their products and services unique and offer them at different price levels. Their aim is to capture the specific customers that will enable the company to maximize profit. Large market share, whether measured in units sold or total revenues, does not always correlate with high profitability. For example, the market share of General Motors in 2011 was 19.4%, more than 6 times the share of BMW at 2.82%. GM reported profits of $9.2 billion while BMW reported profits of about $4.9 billion Euros ($5.3 billion U.S.) during the same period. Whether measured by per unit sales or total revenue, BMW showed a higher degree of profitability than GM. Profit per unit, not just market share, is the goal of most companies. Companies seek to capture as much market share as might be available consistent with their strategy.  To again use the automotive example, BMW knows that not every car purchaser is one of its potential customers. It is a luxury car manufacturer, and less than ten percent of car buyers are in the luxury car market. Luxury car sales make up a tiny fraction of the total 12.7 million cars purchased annually in the US. BMW sold 247,907 cars in 2011, more than any other luxury car maker including GM's Cadillac and Buick lines. Clearly identify the specific market segment you intend to research. It can be general, focusing on total sales, or restricted to specific products and services. You must define the market on like terms as you examine the sales of each company. Otherwise, you are comparing apples to oranges. You can compare a single company's year-to-year performance. Alternatively, you can compare all the companies within a competitive space. Changes in market share might mean the company's strategy is effective (if market share is rising), faulty (if market share falls), or was not implemented effectively. For example, BMW's number of autos sold and their market share increased from 2010. This indicates that their marketing and pricing strategies were more effective than competitors like Lexus, Mercedes, and Acura.
Summary: Understand a company's market strategy. Define the market parameters. Identify changes in market share year to year.

Problem: Article: Any herbs can potentially cause adverse side effects, especially if you’re on daily medications. Always tell your doctor when you’re starting an herbal regimen to find out if this is a safe idea. Chamomile in particular can interact with blood-thinning drugs, so don’t use it if you take blood thinners. Just like any other medication, these herbs are only safe when taken in the correct quantities. Follow the dosage size on every product you use and never take too much. If you don’t know the proper dosage for a supplement you’re taking, ask your doctor about it. Most anxiety-reducing herbs can also cause drowsiness, especially if you haven’t taken them before. When you first start taking a new herb, wait a few hours before driving or operating machinery so you don’t suddenly get drowsy in the middle of a task. Herbal supplements can cause a number of adverse side effects like dizziness, nausea, or heartburn. If you don’t like how something makes you feel, then stop taking it.
Summary:
Ask your doctor before you start taking any herbal supplements. Follow all the dosage or serving instructions that come with herbs. Wait until you know how the herbs affect you before driving. Stop if you experience any adverse side effects.
