It's been another volatile week on the global stock markets as investors grapple with the banking crisis in the United States. But selling equities after prices have fallen is usually a bad move. As this article from Dimensional Fund Advisors explains, long-term investors should resist the urge to "do something" and focus on the bigger picture.
Last Friday US regulators took control of Silicon Valley Bank as a run on the bank unfolded. Two days later, regulators took control of a second lender, Signature Bank. With increasing anxiety, many investors are eyeing their portfolios for exposure to these and other regional banks.
Rather than rummaging through your portfolio looking for trouble when headlines make you anxious, turn instead to your investment plan. Hopefully, your plan is designed with your long-term goals in mind and is based on principles that you can stick with, given your personal risk tolerances. While every investor’s plan is a bit different, ignoring headlines and focusing on the following time-tested principles may help you avoid making shortsighted missteps.
1. Uncertainty is unavoidable
Remember that uncertainty is nothing new and investing comes with risks. Consider the events of the last three years alone: a global pandemic, the Russian invasion of Ukraine, spiking inflation, and ongoing recession fears. In other words, it may have seemed as if there were plenty of reasons to panic. Despite these concerns, for the three years ending February 28, 2023, the Russell 3000 Index (a broad market-capitalisation-weighted index of public US companies) returned an annualized 11.79%, slightly outpacing its average annualized returns of 11.65% since inception in January 1979. The past three years certainly make a case for weathering short-term ups and downs and sticking with your plan.
2. Market timing is futile
Inevitably, when events turn bleak and headlines warn of worse to come, some investors’ thoughts turn to market timing. The idea of using short-term strategies to avoid near-term pain without missing out on long-term gains is seductive, but research repeatedly demonstrates that timing strategies are not effective. The impact of miscalculating your timing strategy can far outweigh the perceived benefits.
3. “Diversification is your buddy”
Nobel laureate Merton Miller famously used to say, “Diversification is your buddy.” Thanks to financial innovations over the last century in the form of mutual funds, and later ETFs, most investors can access broadly diversified investment strategies at very low costs. While not all risks — including a systemic risk such as an economic recession — can be diversified away (see Principle 1 above), diversification is still an incredibly effective tool for reducing many risks investors face. In particular, diversification can reduce the potential pain caused by the poor performance of a single company, industry, or country (1). As of February 28, Silicon Valley Bank (SIVB) represented just 0.04% of the Russell 3000, while regional banks represented approximately 1.70% (2). For investors with globally diversified portfolios, exposure to SIVB and other US-based regional banks likely was significantly smaller. If buddying up with diversification is part of your investment plan, headline moments can help drive home the long-term benefits of your approach.
When the unexpected happens, many investors feel like they should be doing something with their portfolios. Often, headlines and pundits stoke these sentiments with predictions of more doom and gloom. For the long-term investor, however, planning for what can happen is far more powerful than trying to predict what will happen.
FOOTNOTES
1. Consider that a study of single stock performance in the US from 1927 to 2020 illustrated that the survival of any given stock is far from guaranteed. The study found that on average for 20-year rolling periods, about 18% of US stocks went through a “bad” delisting. The authors note that delisting events can be “good” or “bad” depending on the experience for investors. For example, a stock delisting due to a merger would be a good delist, as the shareholders of that stock would be compensated during the acquisition. On the other hand, a firm that delists due to its deteriorating financial condition would be a bad delist since it is an adverse outcome for investors. Given these results, there is a good case to avoid concentrated exposure to a single company. Source: Singled Out: Historical Performance of Individual Stocks (Dimensional Fund Advisors, 2022).

RISKS
Investments involve risks. The investment return and principal value of an investment may fluctuate so that an investor’s shares, when redeemed, may be worth more or less than their original value. Past performance is not a guarantee of future results. There is no guarantee strategies will be successful.
Diversification neither assures a profit nor guarantees against loss in a declining market.
Past performance is not a guarantee of future results. Indices are not available for direct investment; therefore, their performance does not reflect the expenses associated with the management of an actual portfolio
