đ Event Breakdown
Decoding market signals as Trump and Xi prepare for crucial trade negotiations: Tomorrowâs the big day. Trump and Xi are set to meet in Busan, South Korea. This is the first in-person meeting between the leaders since Trumpâs return to office in January.
Talks will center upon tariffs and trade balances, rare earths, fentanyl trafficking, TikTok, and tech exports, specifically Nvidia chips.
Here are some of the top overnight headlines:
- Trump expects to lower fentanyl-linked tariffs on China
- Trump announced a trade breakthrough with South Korea, perhaps increasing leverage going into talks with Xi
- China has purchased 180,000 tons of US soybeans - the first major order in months - signaling progress and a potential easing in trade tensions
Over the last few weeks weâve discussed the approaching trade war tipping point and the implications for markets. Now letâs tie it altogether.
Outcomes from tomorrowâs talks will unequivocally impact the stock market. This is abundantly clear from what transpired on Liberation Day in addition to Xiâs recent rare earths export ban and Trumpâs 100% tariff threat response. Now the question is will markets puke or will they rally tomorrow?
US-China Trade
Prediction markets have become increasingly optimistic a deal will get done in the coming weeks.
Thereâs now a 70% chance (and climbing) that the US and China reach a tariff agreement before the end of the month.
Itâs even more likely (94% chance) an agreement is reached by November 10th.
These are certainly positive signs for markets. However, a critical point of tension right now centers upon Chinaâs rare earths export ban. Two weeks ago we had difficulty reconciling how a tariff agreement could get done without some relaxation on the rare earths export ban.

Well, it finally seems as though those odds are finally increasing.
These are all positive signs for markets, but one has to wonder if an agreement is reached what will the tariff rate ultimately be? Markets are still anticipating a tariff rate between 30% and 40% as they were two weeks ago.
That said, there has been a slight 4% uptick in the probability of rates coming in lower between 20%-30% (24%). In either scenario, prediction markets anticipate much lower than the 100% threat Trump made two and a half weeks ago.
Again, this is all seemingly good news for markets. Letâs drill into what prediction markets are saying on that front.
Will the Stock Market Puke or Rip?
Last week we did a deep dive into stock market forecasts and the bullish indicators present amidst historic economic and geopolitical uncertainty. Since then the bullishness has only continued.
In the last few days weâve seen an increase in the likelihood of the S&P closing at record highs between 7,000-7,200 (27%) and 7,200-7,399 (19%).
Odds centered upon âHow high will the S&P get this yearâ have also increased in recent days. Odds now for â7,000 or aboveâ sit at 85% (up from 40% a week ago) while odds for â7,500 or aboveâ are now at 24% (up from 4% a week ago). Those are big jumps for markets with decent volume (~$116K total).
The bullishness doesnât stop there. The Nasdaq-100 is increasingly trending towards record highs above 24,500 (currently at 84%, up from 67% a week ago).
Thatâs a significant increase in bullishness from our writings a week ago which aligns with the softening of rhetoric between the worldâs global superpowers.
Trumpâs Approval Rating
The state of the economy always plays a significant role in politics and election outcomes.
Is there anything to be gleaned from markets concerning Trumpâs approval rating when it comes to tomorrowâs trade talks and their potential impact on the stock market?
Trumpâs current approval rating according to Real Clear Politics is 45.1%.
Over the last 24-48 hours it is looking more likely his approval rating will decrease to between 44.6%-45% (now up to 45% from 28% a week ago). At the same time, his odds of maintaining an approval rating between 45.1% and 45.5% have decreased to 47% from 53% just two days ago).
It is ultimately looking increasingly likely that Trumpâs approval rating will decrease this week.
What should we make of this?
Thereâs optimism around a US-China trade deal getting done that will reduce economic and geopolitical uncertainty and in turn help propel markets. In spite of that, Trumpâs approval rating is likely to trend downwards.
This divergence is interesting. These markets are not directly correlated of course, but it leads one to believe Trumpâs domestic policy efforts may currently be dragging down his approval in spite of optimism on the global trade front.
So, back to our original question, will the market rip or puke tomorrow?
Signs Point to Stock Market Rally
Tomorrow is an important day for traders and investors. We will learn more about the future of the US-China trade relationship which will have far reaching impacts on the global economy.
As of now, all signs point to a thawing in tensions as means to pragmatically strike a deal. Both leaders recognize the stakes are incredibly high. It is important for them to return to their respective countries and report back to their citizens that progress is being made.
It is not the time for gamesmanship or last ditch efforts to increase leverage. There is pressure on both Trump and Xi to show the world steps forward are being taken. Each leader faces far more downside if the current trade impasse persists.
Markets seem to be sniffing this out in the short-term. Bullish sentiment has ramped up over the last few days as the Trump-Xi meeting approaches, intimating the market too believes strides will be made during tomorrowâs talks.
At this point weâre in âwait and seeâ mode, but donât be shocked if futures rip overnight as the talks kick off at 11a Korea Standard Time.
