Equity Investments - Analyzing a Company - Types of Stock

1. Growth Company and Growth StockA growth company is a company that consistently grows by investing in projects that will generate growth. A growth stock, however, is a stock that earns a higher rate of return over stocks with a similar risk profile.
   
   Feasibly, a company could be a growth company, but its stock could be a value stock if it is trading below its peers of similar risk.

2. Defensive Company and Defensive StockA defensive company is a company whose earnings are relatively unaffected in a business cycle downturn. A defensive company is typically reflective of products that we "need" versus "want". A food company, such as Kellogg, is considered a defensive company. A defensive stock, however, will hold its value relatively well in a business cycle downturn.

3. Cyclical Company and Cyclical StockA cyclical company is a company whose earnings are affected relative to a business cycle. A cyclical company is typically reflects products we "want". A retail store, such as The Gap, is considered a cyclical company. A cyclical stock, however, will move with the market in relation to the business cycle.

4. Speculative Company and Speculative Stock.A speculative company is a company that invests in a business with an uncertain outcome. An oil exploration company is an example of a speculative company. A speculative stock, however, is a stock that has potential for a large return, as well as the potential for considerable losses. An example of speculative stocks can be found in the tech bubble, where investors put money into speculative stocks, but the investor could have been hurt financially or made large gains depending on the stock the investor invested in.

Explanations for the Erratic Price Behaviour of some of the Most Successful and Impressive Enterprises

Growth Stock Paradox: The more successful the company, the greater are likely to be the fluctuations in the price of its shares.

The argument made above should explain the often erratic price behavior of our most successful and impressive enterprises. 

• Our favorite example is the monarch of them all—International Business Machines. The price of its shares fell from 607 to 300 in seven months in 1962–63; after two splits its price fell from 387 to 219 in 1970. 
• Similarly, Xerox—an even more impressive earnings gainer in recent decades—fell from 171 to 87 in 1962–63, and from 116 to 65 in 1970. 

These striking losses 

• did not indicate any doubt about the future long-term growth of IBM or Xerox; 
• they reflected instead a lack of confidence in the premium valuation that the stock market itself had placed on these excellent prospects.
