Markets Brief: Volatility Shines a Light on Small-Cap Stocks
Plus: Corporate bonds, investing mistakes, and energy stocks.

Fed Disappoints the Market
US stocks fell sharply despite the Federal Reserve cutting interest rates by the expected 0.25 percentage points and lower-than-expected inflation. Like a rerun of A Christmas Carol, the joy of Christmas present was replaced by fear over a Christmas yet-to-come as the interest-rate forecasts of individual members of the Federal Open Market Committee (the “dot plots”) indicated fewer rate cuts than expected in 2025 and less support for the economy. You can read more about the implication of the dot plots in this article by senior US economist Preston Caldwell and get more details on the inflation data from Bella Albrecht here.
Corporate Bonds Track Equities
Fixed-income prices also fell over the week. Corporate bonds fell further than Treasuries as credit spreads rose. While the impact on spreads was more muted than during the brief panics of July and September, it is a good reminder that corporate bonds tend to exhibit higher correlation to equities than Treasuries and so should be treated differently when used in portfolios. The value of the US dollar also rose sharply before falling back on Friday to end the week 1% higher.
Volatile Markets Make Mistakes Likely
The sharp fall in stocks on Thursday and partial recovery on Friday was likely exacerbated by fewer market participants being engaged due to the holidays. At these times, it is natural for investors to feel inclined to sell their investments, while others will try to profit from the volatility by making purchases and sales in the hope of short-term gains. When these feelings arise, the apparent indolence of professional investors can seem puzzling or even frustrating. However, the most profitable response to such situations is to maintain a long-term perspective and avoid the flight or fight instinct that grips us.
For most investors, the continued growth in the profitability of well-managed companies, supported by the dynamism of the US economy, will provide almost all the gains over our investing lifetime. We can seek to enhance these returns by favoring undervalued assets over those that are expensive, but this can’t replace the core engine of our portfolios. Consequently, periods of volatility increase the likelihood that we will make mistakes and are periods when we are normally better served by sitting on our hands than making big changes.
Large-Cap Gap
Although the US market became less overvalued as a result of the price movements last week, valuation gaps within the market widened as small companies fared worse than large companies. The gap between large growth companies and small value companies has widened further, with the latter trading at a 13.4% premium to Morningstar’s estimate of fair value while the former is trading at an 11.1% discount. For those investors wishing to exploit this gap in expected returns, Tori Brovet has written about Morningstar’s favored small-cap funds here.
Energy Stocks Under Pressure
At a sector level, technology stocks fared the best while energy and basic materials fared the worst. Energy companies have been dogged by weak demand and fears of excess supply when the current OPEC production cuts are unwound. While the latter appears unlikely in 2025, forecasters such as the International Energy Agency continue to expect supply growth to outstrip demand in 2025. This negativity is weighing on stock prices in the sector, with US energy companies currently priced at a 13.4% discount to fair value. To help investors access this opportunity, Josh Aguilar, Morningstar’s sector director for US energy, highlights the most attractive opportunities in this article.
Expect Market Volatility
Economic data is sparse over the next couple of weeks. While that should reduce the probability of surprises feeding through into asset prices, fewer active market participants will increase the likelihood of further volatility. For those who do want to keep track of the economic and company announcements, find them in this calendar.
