The alpha Brief: Insights on Quant Investing and the alpha Brief Portfolio (aBP)

I am rating this company a Hold because, while stronger refining margins, resilient fuel demand, and efficient operations support earnings growth and cash generation, the cyclical nature of refining profitability and potential margin normalization limit further upside at current valuations.

The artificial-intelligence trade keeps moving outward. First, investors focused on GPUs. Then the bottlenecks moved into memory, networking and optical infrastructure. Now the market is confronting a constraint that sits underneath the entire system.

I am downgrading JinkoSolar from a STRONG BUY to a HOLD. Q2 2026 revenue was $1.82Bn, 14% below consensus, while adjusted loss per ADS widened to $2.54. Gross margin fell to 4.2% from 8.3% in Q1.

The valuation thesis weakened after the shares gained 56.8% from the original article's $247.12 purchase price to $387.61. Consensus also expects 2027 EPS to fall 20% from the 2026 level as margins normalize.

My 2027 model produces $409 Bn of revenue and $11.55 of EPS, slightly above the $11.08 consensus EPS forecast but below the earnings pace implied by unusually supportive Q2 markets.

The operating thesis strengthened. Production reached 4.07 Mn boe/d, the company achieved its $3 Bn cost-saving run rate early, and Hess synergies were raised to $1.5 Bn.

Power generation, grid equipment and critical minerals are becoming increasingly interconnected. Reliable electricity cannot be delivered without generation capacity, transmission infrastructure and the raw materials required to build both.

Q2 revenue rose 21.1% to $391.1 Mn and adjusted EBITDA rose 21.7% to a record $216.8 Mn. Revenue beat consensus, but adjusted EPS of $0.55 missed the $0.67 estimate.

I downgrade GE Vernova from Buy to Hold because stronger execution is now balanced by a demanding valuation and unusually working-capital-heavy cash flow.

I am retaining my Strong Buy rating on Phillips 66 following its second-quarter 2026 results. In my previous analysis, I argued that better refining execution, a growing Midstream business and disciplined capital allocation were making Phillips 66 less dependent on favorable refining cycles. Q2 strengthens that thesis because those structural improvements are now meeting an exceptionally supportive refining environment.

Par Pacific delivered $2.97 Bn of revenue, $571.3 Mn of adjusted EBITDA, and $10.10 of adjusted EPS in Q2 2026. Revenue and EPS beat the public consensus figures of $2.40 Bn and $8.22, respectively.

Q2 Adjusted Earnings reached $9.8 Bn, Adjusted EBITDA was $20.7 Bn, and CFFO reached $21.4 Bn. Free cash flow was $17.5 Bn, helping net debt fall from $52.6 Bn in Q1 to $41.8 Bn and gearing decline to 18.7%.

The biggest question is no longer whether the refining thesis has worked, but how long it can last. Distillate inventories, crack spreads and refinery utilization will be critical indicators as we decide whether to maintain exposure or become more defensive.

I am retaining my Strong Buy rating on PBF Energy (NYSE: PBF) following its second quarter 2026 results. My previous thesis depended heavily on the Martinez refinery returning to full operation, better West Coast refining conditions and measurable savings from the Refinery Business Improvement program. Martinez is now fully operational, refining conditions have strengthened considerably, and the cost program continues to deliver.

Our preferred opportunities combine proven execution with different stages of upside potential. Some of our earlier investment ideas have already delivered substantial returns, while others remain closer to their original publication levels despite meaningful improvements in underlying fundamentals.

I rate Par Pacific Holdings, Inc. (NYSE: PARR) a Buy because I believe the market is undervaluing a high-quality downstream energy company with a unique combination of refining, logistics, retail, and renewable fuels assets. Unlike many independent refiners, Par Pacific has built an integrated platform that generates cash flow across multiple business segments while benefiting from geographically advantaged markets in Hawaii, the Pacific Northwest, and the Rockies.

I am rating JinkoSolar a Strong Buy because it is the undisputed global leader in solar module shipments, trading at a deeply depressed valuation that prices in permanent earnings impairment rather than a cyclical trough followed by a structural recovery.

This company is strategically positioned in the growing clean energy sector and its has a capability to address electricity demand constraints with its distributed, on-site energy systems that offer reliable, grid-independent power.

ExxonMobil achieved stronger core results in the first quarter of 2026, despite disruptions in the Middle East, demonstrating the business's resilience in challenging conditions. As reported in the 1Q 2026 Earnings Release, earnings were $4.2 Bn, or $8.8 Bn when excluding identified items and estimated timing effects.

On valuation, Valero still looks attractive. Its FWD Non-GAAP EV/EBITDA of 6.16x and FWD P/E of 9.33x are below Marathon Petroleum and Phillips 66, while its FWD PEG of 0.19x looks much better than HF Sinclair. In other words, the stock is not priced like a premium stock even though it has many of those qualities.
