Biggest things you look for in a stock?

[michiganfan9]

Now i'm 16 and love to invest. I generally invest in small camp-mid cap stocks because my income isn't that great at my age. I usually look for a steady increase of gross profit, looks for a company with little competition, low p/e ratio and a stock that isn't too overvalued. stocks with free cash flow much greater than their debt (hopefully they have none). And last dividends. I like a stock that gives out dividends because it shows that usually thye are not struggling to bring in cash. What else should I be looking for?
