Diamond Hill Select Fund Q1 2026 Portfolio Update

Diamondback Energy shares rose on a sharp move higher in oil prices, reflecting a broad rally in US oil producers. Capital One underperformed after announcing its acquisition of Brex, while Kimberly-Clark was added to the portfolio following its announced Kenvue acquisition and subsequent share price decline. The article is primarily a market-thematic update rather than a single stock-specific catalyst, with moderate implications for energy and M&A-sensitive names.

Analysis

The common thread is not just M&A headlines, but balance-sheet repricing: when a sector leader or strategic buyer makes a large acquisition, the market usually discounts near-term integration risk faster than it prices medium-term synergies. That creates a window where the acquirer can underperform even if the deal is strategically sound, while adjacent names with cleaner capital allocation or less execution risk can rerate as relative winners. In that setup, sentiment tends to be more important than fundamentals for the first 4-8 weeks, especially when the underlying macro backdrop is stable.

Energy remains the cleaner expression of the current tape because the move is being driven by a marginal change in oil price rather than a company-specific story. The second-order effect is that higher crude tends to widen the performance gap between low-cost, high-beta US producers and diversified energy exposure, because the former reprice faster to spot and show it in equity performance almost immediately. If oil retraces, the trade can unwind just as quickly, so this is a short-duration momentum expression rather than a long-dated structural call.

For KMB and KVUE, the interesting point is that acquisition-related selloffs often overshoot when investors focus on headline deal price and underweight portfolio rotation. A slower, more defensive capital compounder can become more attractive after a pullback if the market is forcing a temporary de-risking discount; the loser is usually the target or the perceived financing beneficiary, which can stay pressured until the market sees evidence that the deal won’t impair leverage or force cuts elsewhere. The key contrarian tell is whether implied execution risk is being priced as permanent rather than transitional.

Key Decisions for Investors

• Stay tactically long FANG for 2-6 weeks while oil momentum persists; use a tight stop if crude gives back the prior spike, since the equity beta is high and can reverse quickly.
• Consider a relative-value long FANG / short a lower-beta integrated or services basket over 1-2 months; the setup favors producers with faster sensitivity to spot prices and less diversification drag.
• Use the KMB pullback to build a starter long over the next 1-3 weeks only if leverage terms remain manageable; risk/reward improves if the market is over-discounting integration friction rather than fundamentals.
• Avoid chasing KVUE here; the cleaner trade is to wait for post-announcement stabilization or use it as a short-term underweight versus peers until merger-related uncertainty clears.
• If you want a hedge against oil retracement, pair the energy long with a partial short in a consumer-staples defensive basket; this keeps you exposed to the relative value shift without taking outright market beta.
