It's been a tough year so far for investors, with a wide variety of assets posting negative returns

In its latest quarterly chartbook, Goldman Sachs analysts point out that everything from gold to mutual funds isn't looking so hot. Meanwhile, the S&P 500 stock index has posted negative returns of 5 percent so far this year.

Still, Goldman analysts led by David Kostin have some suggestions for investors seeking solace in an otherwise troubled trading environment. By looking at companies with the greatest difference between analysts' price targets and the current stock price, they make 40 'buy' and 40 'sell' suggestions.

On that basis, companies including Wynn Resorts, General Motors, Macy's, Apple, Tiffany, and PayPalmakes Goldman's top 40 list you should buy.

Of course, there are a number of firms that represent a lot of downside potential, including Transocean, which Goldman believes has the potential to fall more than 60 percent. Others on the list include Nasdaq, Microsoft, YUM! Brands, Under Armour, and Kellogg.

Of course, the last time Goldman made a big call for the S&P 500-- on August 17, when the bank said the S&P 500 was likely to move sideways and end the year at 2,100 -- was just before the market cracked. They've since revised the call and are now forecasting the S&P 500 will end 2015 in the red at 2,000.

Let's see if their calls on individual stocks fare better.
