The S&P 500 and Nasdaq both hit new all-time highs this week. The US-China trade summit produced a 90-day tariff pause, markets rallied, and the financial headlines are full of celebration.
Here is the thing about all-time highs: they are not a signal to act. They are a signal to think.
For cross-border investors specifically, a market at all-time highs creates a very specific set of decisions that most general-purpose financial content does not address. This post is for people navigating real gains in a cross-border context: two tax systems, two currencies, two sets of registered accounts, and a financial plan that has to hold together on both sides of the border.

First: What Just Happened, and Why It Matters
The Trump-Xi summit delivered a 90-day tariff pause and partial reduction. Markets repriced immediately. The S&P and Nasdaq moved to new all-time highs on the relief. WTI crude, however, was up approximately 10% on the week — not down. The Iran diplomatic stalemate remains unresolved, and Trump’s visit to China concluded without meaningful updates on the energy front. The oil move was driven by geopolitical supply risk, not the trade deal. Cross-border portfolios with meaningful US equity exposure are sitting on very real equity gains right now, while energy prices tell a separate and more complex story.
The 90-day window is not a resolution of the structural US-China trade conflict. It is a pause. History suggests that pauses get extended, renegotiated, and occasionally broken. The disciplined investor does not treat a pause as a permanent change in the landscape.
But the gains that accumulated getting here are real. And real gains, in a cross-border portfolio, require a real conversation.

The ATH Checklist for Cross-Border Investors
When US equity markets are at all-time highs, here is what cross-border investors should be reviewing:
• Review your USD-denominated allocation against your target. All-time highs often mean your US equity weighting has drifted above your intended level. If you set a target allocation for a reason, it still applies when markets are up.
• Think about where gains are sitting. Are your largest unrealized gains in registered accounts (IRA, 401(k), RRSP) or non-registered taxable accounts? The answer changes the conversation completely. Gains inside registered accounts grow without immediate tax drag. Gains in taxable accounts are a decision.
• Consider the currency layer. US equity gains are denominated in USD. If you have Canadian dollar expenses, liabilities, or financial goals, the exchange rate at the time you convert matters. A strong USD relative to CAD can enhance or reduce the real purchasing power of those gains depending on which direction you need to move.
• Assess your capital gains sequencing. In a cross-border context, the order in which you realize gains matters. Canada and the US treat capital gains differently, and realizing gains in the wrong year or the wrong account can create a larger-than-necessary tax bill on one or both sides of the border.
• Check your RRSP and TFSA contribution room. If Canadian-resident clients have gains in non-registered accounts and unused registered contribution room, ATH environments can be an opportunity to reset: realize gains at current values, shelter future growth.
• Revisit your rebalancing triggers. If you use a target-allocation approach with defined bands, an ATH environment often triggers a rebalancing event. Make sure the rebalancing is being executed in a tax-aware way across both jurisdictions.
What Cross-Border Rebalancing Actually Looks Like
Rebalancing a cross-border portfolio is not the same as rebalancing a domestic one. The mechanics are more complex, and the stakes for getting it wrong are higher.
A few principles that matter here:
First, rebalance inside registered accounts where possible. Selling inside an RRSP, TFSA, IRA, or 401(k) does not trigger a taxable event. If you can move from an overweight equity position to your target allocation inside a registered account, you should strongly prefer that path.
Second, in non-registered accounts, be deliberate about which gains you realize in which country. If you are a Canadian resident with a US taxable brokerage account, your gains may be subject to Canadian capital gains inclusion rules and potentially US tax depending on your status. Dual-jurisdiction clients need to model both tax systems before realizing anything.
Third, the 90-day US-China pause creates a window but not certainty. If you are planning to rebalance, do not wait for a specific macro catalyst to trigger the decision. The decision should be driven by your allocation targets, not by your forecast of whether the pause gets extended.

The Emotional Discipline Problem
All-time highs are psychologically hard to sell into. It feels counterintuitive. It feels like leaving money on the table. And if the market continues higher, you will briefly feel like you made the wrong call.
This is the moment where disciplined investing separates from reactive investing. The point of having a target allocation is precisely so that you do not have to make a fresh emotional decision every time the market moves. If your allocation says 60% equity and you are now at 72% because markets ran, the math has already made the decision for you. You are just executing.
The investors who build wealth across decades are not the ones who called the top. They are the ones who maintained their discipline at the top, rebalanced systematically, and kept their financial plans coherent across market cycles.
The Bottom Line
Markets at all-time highs are not a problem. They are a planning opportunity.
For cross-border investors, the opportunity is specific: review your allocation, assess where gains are sitting, think through the currency and tax implications on both sides, and make the decisions that your financial plan has already told you to make.
If you have significant cross-border equity exposure and have not reviewed your allocation since the last major market move, now is exactly the right time. Reach out to the Sartorial team. This is precisely the kind of decision where dual-registered, cross-border expertise makes a material difference in the outcome.
Frequently Asked Questions
Should I sell my investments when markets hit all-time highs?
Not necessarily. All-time highs are a signal to review your allocation, not an automatic trigger to sell. If your portfolio has drifted above your target equity weighting because markets ran, rebalancing may be appropriate. But the decision should be driven by your allocation targets and financial plan, not by the market level itself.
How do I rebalance a cross-border portfolio without triggering a large tax bill?
The most tax-efficient approach is to rebalance inside registered accounts first. Selling inside an RRSP, TFSA, IRA, or 401(k) does not create a taxable event. For non-registered accounts, the order in which you realize gains across jurisdictions matters significantly, and a dual-registered cross-border advisor can help you sequence realizations to minimize combined tax exposure in both countries.
Do I owe capital gains tax in both Canada and the US when I sell US stocks?
It depends on your residency status and the account type. Canadian residents selling US stocks in a taxable account owe Canadian capital gains tax on the gain, reported in Canadian dollars. US persons (citizens, green card holders, or US residents) may also owe US tax. The Canada-US Tax Convention generally prevents true double taxation, but cross-border clients should model both tax systems before realizing significant gains.
What accounts should I rebalance first in a cross-border portfolio?
Always start with registered accounts: RRSP, TFSA, IRA, and 401(k). These allow you to shift between asset classes without triggering taxable events. Only move to non-registered taxable accounts once registered account capacity is used up, and do so with deliberate attention to which gains are being realized in which country and in which tax year.
How does the CAD/USD exchange rate affect my US investment gains as a Canadian investor?
US equity gains are denominated in USD. When you convert to Canadian dollars, the exchange rate at the time of conversion directly affects the real value of those gains. A strong USD relative to CAD means your gains convert to more Canadian dollars. A weaker USD means less. For Canadian-resident investors with USD-denominated assets, currency is a meaningful variable in the total return calculation.
What is a target allocation and why does it matter more at all-time highs?
A target allocation is the planned percentage of your portfolio in each asset class, such as equities, fixed income, or cash. During a strong equity rally, your actual equity weighting can drift well above your target. All-time highs make this drift more likely. Having a target allocation with defined rebalancing bands means you do not have to make a fresh emotional decision every time markets move. You just execute the plan.
