I'll include some direct quotes from the intelligent investor later, if I have time.
DIVIDENDS THE KEY TO RETURNS, EVEN FOR GROWTH STOCKS | PRAGMATIC CAPITALISM
80% of the real returns (adjusted for inflation) over the history of the stock market are from dividends.
Only 20% are from the actual growth of the company. Mostly the increase in price of the stock market is related to inflation. When you adjust for inflation, you find out the only people making money are those receiving dividends.
This doesn't mean you should invest in companies with the largest dividends. Instead try to find large companies, that are going through unpopular times and pay some form of a dividend.
The stock I've done best from was Bank of America. It's dividend is only .01 per share. Not even 1% of their price. But they are a massive bank. The US government has even proclaimed them to big to fail, so I knew my was safe (priority number 1). And their p/e was less than 10 at the time (making it a major bargain).
