For most stock market investors, the name of the game is profit. That being said, even potential investors should be knowledgeable of all the trends that are made by the stock market. Once the trend is identified, it's a simple process to speculate in the market. It's easy to lose sight, however, of the fact that the stock market is all about speculations and an investor can just as easily make or lose thousands of dollars if they don't understand how to read and follow the trend.
A good way to understand the trend of the stock market is by learning how to read chart histories. Chart histories provide historical context, all the ups and downs that occurred in past stock markets. To quote Andy Mayo from Ehow.com, "The trend is your friend until the end when it bends" is an apt way to realize the there are some factors, like the primary trend, involved when considering how to make a profit in the stock market. Although indentifying the primary trend is by far not the only element to consider when figuring out profit, it is by far one of the most important.
Online companies like Stock Profit Calculators are indispensable for anyone interested in buying, selling, trading, or even thinking about getting into the market. If you can correctly input the data, these computers are no brainers for figuring out potential profits. They store calculations for you by putting them into tables saving you the hassle of having to reenter your data each time. They can display such things as what would be an optimal time to dump a stock as well as showing live quotes and stock rankings.
Ultimately, the dream is to make consistent profits on the stock market. While fundamental analysis for medium to long term capital gains and timing the market by trying to spot reversals or advantageous exit and entry points are the typical methods used by investors and traders, remember that the stock market is a zero sum game. The stock exchange is essentially a redistribution center for wealth and in order for you to win, someone else must lose. Profit and loss.
The point being that just because you invested your money in the stock market doesn't give it a life of its own, it's up to the investor to research history, learn the trends and to factor in time, money and emotions when adding up profit potential.
