2015 has been a surprisingly strong year for Unilever ( LSE: ULVR ) (NYSE: UL.US), with the global consumer goods company posting share price gains of 8% since the turn of the year. That's despite emerging markets enduring a challenging period, which shows that investors are still thinking long term when it comes to the company's growth prospects. Of course, Unilever continues to offer hugely consistent growth. Its track record provides evidence of this, with the company posting a rise in its bottom line in four of the last five years. Similarly, consumer credit company, Experian ( LSE: EXPN ), also has a very strong track record of growth, with its earnings having risen in each of the last five years. And, looking ahead, further growth is expected, but the price that investors are being asked to pay for the company's forecasts appears to be rather high. For example, Experian is due to see its bottom line rise by 1% in the current year, and by a further 7% next year.
