With the bull market now 6 1/2 years old, some of Wall Street's investing pros warn that it's a good time to begin preparing for an eventual end to the bull market.

Others think that you can stay bullish, but they recommend having greater exposure to some industries than others.

"We believe Energy and Industrial positions should generally be reduced heading into yearend as operating disappointments are likely through 1Q16, in favor of over weights on Health Care and consumer exposed Tech companies and select Financials and Consumer companies," Deutsche Bank's David Bianco wrote in a note to clients Sunday.

Bianco offered a list of the big companies to invest in for the upcoming year. They're all rated Buy by Deutsche Bank analysts. We've compiled that list, which features companies with market caps over $10 billion, price-to-earnings ratios below 22, and positive 2015 earnings per share growth.

The companies are assembled below by industry, along with Deutsche Bank's price target, the company's share price when the note was published, the company's price-to-earnings based on 2015 earnings per share, and Deutsche's 2016 projections for earnings per share growth. Additionally, for the companies that have reported Q3 earnings, we've pulled a quote from an executive during the earnings conference call if available.
