Blue-chip = Stocks in large, well-known, financially solid companies that have been around for a long time like General Electric and Proctor & Gamble.

Income = Stocks in well-established, older companies that are no longer growing -- like utility companies.  These companies pay out their profits to the stockholders.  These pay-outs are called "dividends."

Growth = Stocks in smaller and often fairly new companies who are growing a lot faster than their competitors.  Most of the money made by these companies (the profit) is put back into the company for more growth and expansion.  Because of this, they don't pay dividends to the stockholders.

Value = These stocks are thought to be a "good bargain."  What this means is that, for some reason, the stock are selling for less than they should be.  The company might be really good, but going through a difficult time...  During these times, the price of their stock is low.  The great companies recover and the value of their stock soars.

Blend = This is just a combination of growth and value.

Speculative = These stocks carry a high level of risk and can quickly rise or fall without warning.  These can be highly profitable... Or you could lose your shirt!

The following are categorized by the value of all shares in the company.  They take the number of shares and multiply it by the current price.  These values will vary a bit depending on who you talk to.
