Here are 10 things you should know for Monday, Dec. 28:

1. -- U.S. stock futures were tipping lower as investors seem to anticipate that the last week of trading in 2015 will push returns for the Dow and the S&P 500 into the red for the year.

European stocks were lower, as the German DAX and French CAC 40 were falling by 0.4% and 0.2% respectively. The British FTSE remained closed for the Christmas holiday.

2. -- The economic calendar in the U.S. on Monday includes the Dallas Fed Manufacturing Survey at 10:30 a.m.

3. -- U.S. stocks on Thursday sent mixed signals in a short week of trading with few shares changing hands. Friday was a market holiday for Christmas, and markets closed at 1 p.m. on Thursday.

The S&P 500 (SPY - Get Report) dropped 0.16% to 2,060.99. The Dow Jones Industrial Average (DIA - Get Report) fell 0.29% to 17,552.17. The Nasdaq (QQQ - Get Report) edged 0.05% higher to 5,048.49.

4. -- Investors are wondering whether the S&P 500 and the Dow can eke out gains for the year. At Friday's market close, the S&P 500 was up a mere 0.1% for 2015, and the Dow is down 1.52% for the year so far. The Dow has historically had a strong close to the year, but it has a fair bit of ground to make up over just four days left of trading before it could enter the black for the year.

Consumer confidence numbers and housing data this week will help determine how the markets cap off 2015.

5. -- Commodity markets are coming off a rally last week as crude oil prices ticked higher. But as the new week begins, oil prices were not going much of anywhere. In an unusual shift, U.S. crude oil, as represented by West Texas Intermediate crude, rose above international Brent crude oil prices.

WTI crude was at $38.10 and Brent crude was at $37.89. Those prices are near the lows for 2015.

6. -- The CEO of Valeant Pharmaceuticals (VRX) , Michael Pearson, was hospitalized for treatment of pneumonia. Valeant stock has fallen more than 50% since its peak in August, as investors question the company's sales numbers and as lawmakers inquire about the company's price hikes.

Valeant has also faced pushback for its relationship with the mail-order pharmacy Philidor Rx Services, which has been accused of changing doctors' orders to require name-brand pharmaceuticals. Valeant has ended its relationship with Philidor. 

7. -- Online shopping has become more central to the holiday shopping season. But that presented challenges to delivery companies like FedEx (FDX - Get Report) , which was criticized for delivering some packages late. Some drivers delivered packages on Christmas day to catch up. Rival UPS (UPS - Get Report) appeared to be running according to schedule.

In premarket trading, FedEx stock was not moving much from its drop of 0.71% on Thursday.

8. -- China Telecom (CHA - Get Report) stock was falling in Hong Kong trading as its chairman was said to be targeted by an anti-graft investigation. Chang Xiaobing, the chairman, moved from China Unicom to China Telecom in September.

It is expected that China Telecom will appoint an interim chairman as Chang's investigation unfolds.

9. -- Bond investors are preparing for a rocky ride as interest rates have begun ticking upward. Junk bond investors in particular are seeing volatile prices as investors abandon more risky bond funds.

Analysts at Deutsche Bank said they expect the bond market to become more unpredictable. The bank anticipates a "baby tantrum" as the Fed raises interest rates in 2016, pushing down the price of U.S. Treasury securities.

10. -- Anavex Life Sciences (AVXL) reports its earnings results Monday.
