Blackstone's Byron Wien unveils his big surprises for 2016

For the 31st year in a row, Blackstone’s vice chairman and investing guru Byron Wien has released his 10 surprises for the year.

These are things Wien believes have a better-than-50% chance of happening, but the average investor anticipates a less than 30% likelihood of occurring.

Wien started this tradition in 1986 when he was Morgan Stanley’s top investment strategist, and he continued it when he joined Blackstone in 2009.

The predictions span from political — the Democrats will take back the US Senate — to economic — the Fed will only hike interest rates once in 2016.

Check out all 10 of his surprises, along with 5 that just missed the cut, below.

1. Hillary wins, and the Democrats take back the Senate.

'Riding on the coattails of Hillary Clinton, the winner of the presidential race against Ted Cruz, the Democrats gain control of the Senate in November.

'The extreme positions of the Republican presidential candidate on key issues are cited as factors contributing to this outcome. Turnout is below expectations for both political parties.'

2. The US stock market declines for the year.

'The United States equity market has a down year. Stocks suffer from weak earnings, margin pressure (higher wages and no pricing power) and a price- earnings ratio contraction. Investors keeping large cash balances because of global instability is another reason for the disappointing performance.'

3. The Fed hikes only once.

'After the December rate increase, the Federal Reserve raises short-term interest rates by 25 basis points only once during 2016 in spite of having indicated on December 16 that they would do more.

'A weak economy, poor corporate performance and struggling emerging markets are behind the cautious policy. Reversing course and actually reducing rates is actively considered later in the year. Real gross domestic product in the U.S. is below 2% for 2016.'

4. Foreign investors leave the US.

'The weak American economy and the soft equity market cause overseas investors to reduce their holdings of American stocks.

'An uncertain policy agenda as a result of a heated presidential campaign further confuses the outlook. The dollar declines to 1.20 against the euro.'

5. China has a dismal year.

'China barely avoids a hard landing and its soft economy fails to produce enough new jobs to satisfy its young people. Chinese banks get in trouble because of non-performing loans. Debt to GDP is now 250%.

'Growth drops below 5% even though retail and auto sales are good and industrial production is up. The yuan is adjusted to seven against the dollar to stimulate exports.'

6. The refugee crisis pushes the EU to the edge of breaking up.

'The refugee crisis proves divisive for the European Union and breaking it up is again on the table. The political shift toward the nationalist policies of the extreme right is behind the change in mood. No decision is made, but the long-term outlook for the euro and its supporters darkens.'

7. Oil 'languishes' around $30

'Oil languishes in the $30s. Slow growth around the world is the major factor, but additional production from Iran and the unwillingness of Saudi Arabia to limit shipments also play a role.

'Diminished exploration and development may result in higher prices at some point, but supply/demand strains do not appear in 2016.'

8. New York and London real estate prices crash.

'High-end residential real estate in New York and London has a sharp downturn. Russian and Chinese buyers disappear from the market in both places. Low oil prices cause caution among Middle East buyers. Many expensive condominiums remain unsold, putting developers under financial stress.'

9. The US 10-year Treasury yield stays below 2.5%

'The soft U.S. economy and the weakness in the equity market keep the yield on the 10-year U.S. Treasury below 2.5%. Investors continue to show a preference for bonds as a safe haven.'

10. Global GDP growth slows to below 2%.

'Burdened by heavy debt and weak demand, global growth falls to 2%. Softer GNP in the United States as well as China and other emerging markets is behind the weaker than expected performance. '

The also-ran predictions: Japan gets out of recession, terrorists are not successful, new treatments for cancer and more.

  • 'As a result of enhanced security efforts, terrorist groups associated with ISIS and al Qaeda do NOT mount a major strike involving 100 or more casualties against targets in the U.S. or Europe in 2016. Even so, the United States accepts only a very limited number of asylum seekers from the Middle East during the year.
  • 'Japan pulls out of its 2015 second half recession as Abenomics starts working. The economy grows 1%, but the yen weakens further to 130 to the dollar. The Nikkei rallies to 22,000.
  • 'Investors get tough on financial engineering. They realise that share buybacks, mergers and acquisitions, and inversions may give a boost to earnings per share in the short term, but they would rather see investment in capital equipment and research that would improve long-term growth. Multiples suffer.
  • '2016 turns out to be the year of breakthroughs in pharmaceuticals. Several new drugs are approved to treat cancer, heart disease, diabetes, Parkinson's and memory loss. The cost of developing the breakthrough drugs and their efficacy encourage the political candidates to soften their criticism of pill pricing. Life expectancy will continue to increase, resulting in financial pressure on entitlement programs.
  • 'Commodity prices stabilise as agricultural and industrial material manufacturers cut production. Emerging market economies come out of their recessions and their equity markets astonish everyone by becoming positive performers in 2016.'
