When looking for companies to invest in, one of the most important things to look for is increasing net income. As an investor we want to purchase shares in companies that not only make money but have ways of growing the amount of money they make year after year. This is why when I do a stock analysis, one of the metrics I look for is net income. I look for a general uptrend in the net income from year to year. I measure the growth rate of net income for the company over the past 10 years and the past couple years.
