The Iran War: Navigating Stock Market Volatility During Uncertainty

By Charles Sherry, MSc

In the early hours of February 28, global markets were shaken by significant geopolitical developments, as the U.S. and Israel carried out coordinated strikes on Iran that resulted in the death of Iran’s Supreme Leader. Iran responded with missile strikes, which escalated tensions and raised uncertainty in global markets.

It’s not surprising to see heightened volatility in the early stages of a conflict, especially one without a clear endgame.

A short-term risk-off response, with pressure on equities and upward movement in oil prices (due to possible supply disruptions), is not surprising in this environment. The U.S. dollar has also strengthened, benefiting from global inflows as it resumes its traditional role as a safe-haven currency.

In moments like these, it’s natural to feel uneasy. Headlines are dramatic, markets react quickly, and uncertainty can make even seasoned investors uncomfortable.

But here’s what I want to emphasize:

1. Market volatility is normal during a geopolitical crisis

Market behavior in response to geopolitical events often follows a familiar pattern: a reaction—which can sometimes be sharp—a rise in volatility, and then a reset because investors attempt to price in the economic impact at home.

In the immediate aftermath of significant events, markets often stabilize more quickly than expected.

How the hostilities may impact the broader U.S. economy is unknown right now, but I believe it will play a bigger role for investors over the medium term.

2. Your financial strategy and volatility

Financial professionals design portfolios with the understanding that unforeseen events, including geopolitical tensions, economic shifts, and policy changes, will occur.

Your strategy likely incorporates diversification, risk management, and long-term goals to help reduce risk and weather periods of turbulence.

3. Staying invested remains the most reliable long-term approach

Times like these can tempt investors to make quick, emotion-driven moves. But historically, reacting to headlines has often led to worse long-term outcomes than sticking with the plan.

Markets have absorbed wars, recessions, pandemics, political crises, and unexpected global shocks, and long-term investors have historically been rewarded for their patience.

4. Financial professionals are monitoring developments closely

While I don’t recommend making investment decisions based on short-term news or emotions, your financial professionals will be continuously monitoring the situation, the market response, and any potential implications for your portfolio.

If market conditions shift in a way that warrants action, they will communicate proactively.

Final thoughts

Events unfolding in the Middle East are serious, and markets may remain volatile in the coming days and weeks. But volatility alone is not a reason to abandon a well-constructed financial strategy.

As always, I encourage you to reach out to your financial professional if you have questions, concerns, or simply want to talk through what this means for your personal financial goals. They’re there to provide clarity, perspective, and guidance, especially when the news feels overwhelming.

We get through moments like these by staying disciplined, thoughtful, and focused on what we can control.

March Madness—Smart Tax Moves That Save You Money

The April 15th tax deadline is just around the corner. For some, you’ll file and be done with the madness sometime in March. Others will sneak in just under the deadline.

You may carve out some time to file with a software package. Or, given the complexity of your situation, you hand off your records to your tax advisor.

That said, whether you put an “exclamation point” on the 2025 tax year over the coming weeks or file an extension, this is an opportune time to offer up smart tax moves that can save you money when you file and put you on the path to saving money in tax year 2025 and 2026.

Do you obtain your insurance through the Affordable Care Act (also known as Obamacare)?

If you are receiving a subsidy for your monthly premium, you want to be very careful that your income does not exceed eligibility—400% of the poverty line. Please note that enhanced subsidies expired in 2025, and the so-called “benefits cliff” returns in 2026.

Also, please note that some state calculators might not have the latest 2026 income guidelines. If you have questions, your financial professional can help guide you.

Income limits are based on modified adjusted gross income (MAGI). For most, your AGI (adjusted gross income) is identical to your MAGI.

What is MAGI? It’s not a line on your tax return. MAGI equals AGI + certain adjustments added back in. The adjustments can vary by situation and include non-taxable Social Security payments and foreign earned income exclusions.

Reviewing the guidelines for the 48 contiguous states plus D.C., the poverty line in 2026 is $15,960 for a household of one.

If that individual earns just $1 more than 400% of the poverty line, approximately $63,840, he/she will be required to repay the entire premium, which could mean a tax bill approaching $10,000. It depends on the person’s age. The older the individual and the lower the initial income estimate, the greater the subsidy.

Younger folks will receive a much lower premium. Still, you’ll be forced to return it if your income exceeds the threshold.

For a family of two, the threshold is approximately $86,560. If you receive that monthly subsidy, you could be liable for up to $20,000 if the limit is exceeded.

That is a painful awakening, and one must be careful with wages, dividends, interest, capital gains, and retirement withdrawals, which risk pushing a recipient of the subsidy over the limit.

If you would like assistance, your financial professional can model not just tax brackets but also effective marginal rates that are created by lost benefits when doing tax planning, including ACA.

MAGI also affects Medicare premiums.

For those with higher AGIs, you can expect to pay an additional amount for insurance.

For example, individuals with a MAGI above $109,000 up to $137,000 and married couples with a MAGI above $218,000 up to $274,000 will pay an additional $81.20 per month for Part B and an additional $14.50 per month for prescription drug coverage, according to Social Security.

This rises to an additional $487 and $91 per month for individuals with a MAGI equal to or above $500,000 and married couples with a MAGI equal to or above $750,000.

With this in mind, let’s review various ways you may lower your MAGI for tax years 2025 and 2026.

Are you eligible to contribute to a traditional IRA?

For 2025, the total contributions you make for all of your traditional and Roth IRAs must not exceed $7,000 ($8,000 if you’re age 50 or older). The last day to make a contribution for tax year 2025 is April 15, 2026.

For tax year 2026, the total contributions you make each year to all of your traditional IRAs and Roth IRAs may not exceed $7,500 ($8,600 if you’re age 50 or older), or if less, your taxable compensation for the year.

For example, if your taxable compensation is low—let’s say $3,000—your contribution cannot exceed $3,000 for that year.

Consider a spousal IRA—an IRA owned by a nonworking person with a working spouse.

While Roth IRAs can be quite advantageous, as withdrawals are designed to be tax-free if certain rules are met, your contribution is not tax deductible and won’t lower your MAGI.

You can contribute to a traditional or Roth IRA even if you participate in another retirement plan through your employer or business. However, you may not be able to deduct all your traditional IRA contributions if you or your spouse participates in another retirement plan at work. Roth IRA contributions are limited if your income exceeds a certain level.

If you are self-employed, you may consider a SEP-IRA, which has much higher contribution limits—for 2025, the limit is 25% of an employee’s total compensation, up to $70,000. The SEP IRA contribution limit for 2026 is 25% of an employee’s total compensation, up to $72,000.

You can set up a SEP plan for a year that is as late as the tax due date (including extensions) of your business’s income tax return for that year. In other words, if you haven’t filed your 2025 business return, you may consider a SEP-IRA for 2025.

Is your health insurance plan HSA- (health savings account) eligible?

If so, you may contribute up to $4,300, or $5,300 if you are 55 or older.

In tax year 2026, that rises to $4,400, or $5,400 if you are 55 or older. You have until the tax deadline to make the contribution—April 15, 2026 for tax year 2025.

Withdrawals used for eligible healthcare expenses are tax-free.

If you are 65 or older, you may withdraw from your HSA to pay for Medicare premiums. Additionally, you may also withdraw from an HSA without penalty for non-qualified expenses if you are over 65, but you will pay taxes on the withdrawal. There are no required minimum distributions (RMDs).

Required minimum distributions (RMDs) will increase your AGI and MAGI.

Deadlines for RMDs—You generally must start taking withdrawals from your traditional IRA, SEP IRA, SIMPLE IRA, and retirement plan accounts when you reach age 73.

You have until April 1st of the year after you turn 73 to take your first RMD.

If you turned 73 in 2025, your first RMD is due by April 1, 2026, and your second RMD is due by December 31, 2026.

If you turn 73 this year, you may wait until April 1, 2027, to take your first RMD, but if you place two RMDs into tax year 2027, you run the risk of landing in a higher tax bracket in 2027.

The One Big Beautiful Bill Act (OBBBA) creates several new tax benefits, including:

  1. Beginning in the 2026 tax year, non-itemizers may deduct cash donations to an eligible charity—up to $1,000 for single filers or $2,000 for married couples filing jointly. Please note that only CASH donations are eligible for a deduction. Noncash items, such as clothing or household goods, donated to a charity do not qualify.

    For those in the 37% bracket, only 35% of the donation is tax-deductible.

    Itemizers that make charitable contributions may claim a tax deduction to the extent that qualified contributions exceed 0.5% of their AGI. For example, a couple with an AGI of $300,000 could only deduct charitable donations in excess of $1,500.

  2. Here’s something worth keeping in mind. Starting in 2027, the OBBBA introduces a new tax credit that allows you to claim up to $1,700 per person when you donate to organizations that provide scholarships for private or religious K–12 schools.

    You can take this credit even if you don’t itemize your deductions.

  3. Additionally, as we’ve discussed before, there are new benefits that apply to overtime, tips, and Social Security.

Because tax rules are complicated, your financial professional is there to help where they can. For advice specific to your circumstances, your tax advisor can provide personalized guidance.

February hits a roadblock

After an upbeat start to the year, uncertainty crept into market sentiment last month, compliments of artificial intelligence. Yes, that’s right—AI. AI has been a powerful driver over the last couple of years, but fears that AI could disrupt profitable models encouraged some investors to re-evaluate long-held positions.

The software sector has seen one of the sharpest retreats, with a Standard & Poor’s index of software companies falling about 20%, according to Yahoo Finance.

Recent releases from AI developers have raised fears that certain software-as-a-service models may face pricing pressure or declining demand, as new tools take on legal, analytical, and administrative work.

Massive AI expenditures by major firms are also raising questions, even as demand for AI-related services is soaring.

Perhaps this is simply a wave of profit-taking after an exceptional run-up. The sharp decline in software also appears to reflect a “shoot first, ask questions later” reaction. It’s not as though AI models are on the verge of displacing well-established firms, many of which just reported strong quarterly earnings.

However, instead of cannibalizing software companies, others argue that the fear is exaggerated, as AI might boost efficiency as firms create new software products.

Other sectors, including energy, industrials, materials, and consumer staples, have generated double-digit returns since the beginning of the year, according to StockCharts.

Tariffs overturned in landmark ruling that’s set to reshape policy

Well, not all tariffs, but the tariffs the president has predominantly used since taking office last year, including the so-called Liberation Day tariffs imposed last April.

In a landmark ruling, the Supreme Court struck down tariffs enacted under the International Emergency Economic Powers Act (IEEPA).

Nonetheless, the president remains undeterred in his desire to use tariffs to shape U.S. trade policy.

He has other options at his disposal. With the exception of one untested Depression-era law, other avenues available to him are not as sweeping as the ones used under IEEPA.

Some require formal investigations. Others limit the tariff and duration.

Private credit—lending provided by non-bank institutions—has become an issue for some investors.

Private credit has grown rapidly in recent years, but transparency is also limited since loans are often illiquid and lightly regulated. As economic growth moderates, there are some concerns that stress in private credit could surface unevenly.

It’s not a big problem today, but it’s an issue that bears watching.

Distributions from traditional IRAs and employer sponsored retirement plans are taxed as ordinary income and, if taken prior to reaching age 59½, may be subject to an additional 10% IRS tax penalty. A Roth IRA offers tax free withdrawals on taxable contributions. To qualify for the tax-free and penalty-free withdrawal of earnings, a Roth IRA must be in place for at least five tax years, and the distribution must take place after age 59½ or due to death, disability, or a first time home purchase (up to a $10,000 lifetime maximum). Depending on state law, Roth IRA distributions may be subject to state taxes.

Before rolling over your retirement account, consider all available options, which include remaining with your current retirement plan, rolling over into a new employer’s plan or IRA, or cashing out the account value. When deciding between an employer-sponsored plan and IRA, there may be important differences to consider—such as range of investment options, fees and expenses, availability of services, and distribution rules (including differences in applicable taxes and penalties). Depending on your plan’s investment options, in some cases, the investment management fees associated with your plan’s investment options may be lower than similar investment options offered outside the plan.
