1/ MIDTERM MADNESS

If the last five U.S. midterm elections are anything to go by, investors should be long U.S. stocks on Tuesday to make the most of a knee-jerk upwards move - no matter what the outcome. Equities have risen the day after each of the past five midterms.

During President Barack Obama’s second term in November 2014, stocks rose 0.6 percent when Republicans made broad gains and took control of the Senate. Energy stocks got a particular boost on hopes of approvals for pipelines. And Obama’s first-term midterm elections also saw stocks grind higher after Republicans took control of the House.

Going back to 2006 during President George W Bush’s second term, stocks nudged 0.2 percent up when Democrats took control of the house; while in 2002 stocks rose 0.9 percent.

A Republican win this time around, that allows them to retain total control of Congress, could boost stocks as it would increase the chances of more tax reform and further de-regulation. Still, a Democratic takeover of the House may not significantly shake the market if it has effectively been priced in - offering the prospect of gridlock and stability in policy.

2/ YUAN LOVE?

Is there light at the end of the trade war tunnel? U.S. President Donald Trump and Chinese President Xi Jinping both seemed optimistic about resolving their bitter trade dispute after Thursday’s phone discussion and ahead of a high-stakes meeting at the end of November in Argentina.

Hopes for a possible deal propelled the yuan away from 7 the threshold to the dollar, for now. The currency had been under pressure amid worries over slowing growth in the world’s second largest economy.

And despite a raft of stimulus measures announced by Beijing having already brightened investors’ mood, the jury is still out as to whether the yuan could crash through that key level, according to a Reuters poll.

If it does, consensus predicts the move to be gradual unless economic conditions in China deteriorate further. Trade data out this week will surely be scoured for clues on that.

3/GREAT EXPECTATIONS

As the European earnings season continues to rumble on, analysts are scratching their heads as to what exactly triggered a sharp selloff across global equity markets last month, which seems to have hit price performance but left earnings expectations largely intact.

Some say investors were just pricing in the fact U.S. stocks aren’t going to be able to provide 20 percent earnings growth every quarter - and taking prices down from their exuberant record high levels.

If they’re beginning to look for alternatives to the United States that still have some earnings improvement to deliver, Europe is starting to look viable. Analysts expect quarterly year-on-year earnings growth in Europe to edge above those in the U.S. in 2019.

Yet in the short-term, investors still have a few hurdles to jump - most notably Italian banks’ earnings this week which could deepen the gloom around lenders’ ability to withstand the steep sell-off in government bonds.

4/NOVEMBER PAIN

Last week’s sterling rally was the second biggest of the year. Fuelled by reports that the United Kingdom and the European Union have made progress on a deal to give London basic access to EU markets after Brexit and gains in global stocks, traders lost no time in snapping up the heavily shorted currency.

But some warn that markets may be getting overly excited. While expectations of a deal at a summit on Nov. 21 have grown, domestic political challenges still abound and market indicators reflect those concerns.

One-month sterling risk-reversals GBP1MRR=, a ratio of puts to calls on the currency and a barometer of investor bearishness, hold near two-year highs, indicating uncertainty remains high.

Morgan Stanley strategists say market sentiment is extremely bearish on sterling with gauges indicating traders are paying more premiums to buy currency options to brace for a rocky ride ahead. And expectations are that roller coaster ride may last for some time with implied volatility curve spreads between 1-year and 1-month options near its flattest levels this year.

5/ TURKEY TWIZZLER

Turkey’s inflation data exceeding forecasts and surging to above 25 percent in October makes for uncomfortable reading.

But inflation at 15-year highs isn’t the only pain point: The impact of the lira’s steep decline on the economy is still being felt with key indicators such as consumer and economic confidence falling to long-time lows and the government cutting its growth forecasts for the next three years.

And there could be more pressure in store for the battered currency, which has weakened more than 30 percent since the start of the year. Ratings agency Moody’s has said recently announced tax cuts could boost consumption temporarily, but are credit negative and risk rekindling pressure on the lira.

So having been charging back into Turkey in recent weeks, investors might begin to remember why they left in the first place.
