If you’re like me and spend your first waking moments catching up on the news, you’re probably exhausted. The headlines suck you in, only for the article to then stir up a whirlwind of aggravation. Let’s just say managing these reactions has become a fine art.
Now, with everything going on today — the ever-changing tariff landscape, uncertainty surrounding significant global conflicts, and earnings surprises cutting both ways — it can feel impossible to sit down and think slowly and critically about your equity portfolio.
Here’s the truth, though: there’ll be no end to big headlines and no “perfect” allocation. One of the few things investors can do in this environment is stick to a reliable framework that suits their horizon and needs. For some of us, factor investing can be a valuable part of that.
The fact(ors) of the matter
For the sake of this discussion, we’ll define factors as characteristics that can help explain investment performance in the equity markets. Investors often calibrate exposures to different factors in efforts to help lower risk, increase diversification, and/or capture excess returns. You won’t be surprised by the factors we’ll touch on here; value, momentum, and growth have dominated performance-focused headlines over the last decade.
Over the last ten years, some of these factors have outperformed the market, while others have matched or underperformed. The factor rotations we’ve witnessed are largely related to hiccups and growing pains in the macro economy; think tech selloffs, changes to interest rate regimes, and global trade order reorganizations. Some investors might choose to tilt their portfolios around these rotations, others focus more on the outcomes from bottom-up stock selection, and still others take a wholly more passive approach that prioritizes broad market exposure. Let’s have a look at what each factor claims to offer.

Value investing: Shooting for under par
Let’s define the value factor as attempting to capture excess returns of stocks that are priced at a discount relative to their fundamental intrinsic value. Basically, the value factor is aiming to get more for less, if you will; it’s trying to complete the course in fewer strokes than anticipated. As we saw in Augusta, though, coming in under isn’t always enough to best the reigning champ.
Over the performance period of May 31, 2016 to April 13, 2026 in the graph above (the “Performance Period”)1, value markedly underperformed the broad market and the growth and momentum factors.2 Within that same Performance Period, though, we found that value had some standup moments that may have served investors when the broad market was comparatively weak. That’s where a value product and an appropriate allocation suited to your goals could have come in handy.
Momentum investing: Objects in motion…
For the reward of a self-administered pat on your back, finish the back half of Newton’s first law of motion.
Alright, fine. An object in motion stays in motion. This is precisely what the momentum factor seeks to capture—excess returns over the market from companies with a relatively recent track record of strong performance. The assumption is that those companies should maintain their momentum (on the nose, I know, but it really is that simple) and that one can scoop some cream off the top by directly exposing their portfolio to this factor.
Over the Performance Period1, the momentum factor tracked large caps by the slimmest margin. We believe this comes down to the self-fulfilling prophecy of index and momentum factor performance. Market cap weighted indices can be whipsawed by the very positive or very negative performance of their largest companies. Therefore, when the top of the S&P 500 or Russell 1000 are leaving scorched tire tracks on the road, you’d expect to see them making up a good chunk of a momentum factor product.
Growth investing: Growing the distance
Last but certainly not least, we have growth. At a high level, the growth factor targets companies that demonstrate above-average earnings and/or revenue growth compared to the broad market. This market is no stranger to the headlines around high-flying growth companies.
Today, these are largely the Mag 7 and every major corporation related to either AI agents, data centers, or semiconductors. In years past, it was a cohort of enterprise software companies that swelled to the top of the market and have recently pulled back on perceived competition from AI capabilities.
The allure seems simple, right?
As with other factors, the key is managing one's direct exposure to growth. Growth does not imply impenetrability. Over the Performance Period, growth outperformed value, momentum, and the broad market by robust margins. But, in the same way that value has shown more robust performance in certain parts of the business cycle, growth companies have faced their own trials. Remember the tech downturn of 2022? No one was singing about growth then.
Now, factor investing – or really any particular strategy – alone won’t quiet the noise of the daily headlines. They’re still going to come and we’re all still going to be beautifully irrational human beings (check out Dan Ariely’s Predictably Irrational, if you haven’t yet). I’m still going to open up my preferred news sites and crank on financial radio with my morning coffee. And, let’s be real, do you really want me to do anything less? Knowing in and of itself doesn’t create that panicked, pants-down feeling; lacking a path forward does that. But with a plan in place, potentially one that includes tilting in and out of certain factors, investors have a chance to feel more grounded even when the market winds are sweeping up portfolios left and right.
Until next time,
Shelby

2 Index Selection Methodology: 1) Identify the largest factor ETFs by AUM: Vanguard Value ETF, Vanguard Growth ETF, iShares MSCI US Momentum Factor ETF. 2) Identify the respective indices and inspect the methodology. 3) Select CRSP Large Cap Value Index based on a) it serves as benchmark for the largest value factor ETF and b) has the strictest rules for assigning stocks as either Value or Growth. 4) Select the CRSP Large Cap Growth Index based on the same logic as CRSP Large Cap Value 5) Select MSCI USA Momentum SR Variant Index, as a) it serves as the benchmark for the iShares MSCI USA Momentum Factor ETF.
Other indices for all factors were examined and rejected due to the laxity of their construction. A fact which permitted stocks to flow very easily from one index to the other and skew factor performance.
The Russell 1000 was chosen to represent the market. This was most appropriate to represent ‘the market’ due to the Large Cap specificity and lean of the three factor indices.
