the morning I thought I was set
I remember exactly where I was sitting. October 11, 2023, a Wednesday, around 9:15 AM eastern time. My phone buzzed with a CNBC push notification that Chevron had agreed to buy Hess Corporation for $171 per share in an all-stock transaction valued at approximately $53 billion. I'd been clutching 600 shares of Hess since June 2021, when I picked them up at $108 a pop after reading an analyst report about their Guyana operations. The stock popped to $163 that morning, and I remember the sick-sweet feeling of watching my portfolio jump almost $33,000 in a single session. I sat there at my kitchen table in Hoboken, coffee going cold, refreshing my Fidelity app every thirty seconds like an addict. I should have sold some right then. I didn't. That decision cost me more than I like to admit.
my history with bad timing
I'd been down this road fore. In 2020 I got burned clutching Altria when the Juul writedowns vaporized $8 billion in equity overnight. You'd think I'd learn. But the Chevron deal read different. It had regulatory approvals from five outta six required agencies. The FTC had signed off in late 2024. European regulators gave the green light in January 2025. Everythin pointed toward a mid-2025 closing, and by late 2025, the spread between Hess's trading price and the implied Chevron deal value had narrowed to less than 3%. Every finance podcast I listened to said it was basically a done deal. My investment advisor at the time, a guy named Greg who functioned out of a WeWork in Jersey City, told me to hold steady. He said the deal was as close to free money as you'd find in public markets. I believed him.
the Guyana problem nobody wanted to talk about
The one risk everyone maintained brushing off was the ExxonMobil arbitration clause. Hess held a 30% stake in the Stabroek Block offshore Guyana, one of the most prolific oil discoveries of the last decade, producing over 600,000 barrels per day by early 2025. Exxon operated that block, and their joint operating agreement contained a pre-emption right that basically said if Hess tried to sell its stake, Exxon had first dibs. Chevron's lawyers argued the all-stock merger didn't trigger that clause. Exxon's lawyers disagreed. I poked at the arbitration filings during the summer of 2025, trying to make sense of the legalese, but it was dense. Dense enough that most retail investors, myself included, just shrugged and moved on.
Hefty mistake. I jotted down a note in my investing journal on August 19, 2025 that read: "Exxon arbitration is the only real risk left, but market is pricing in a 95% chance of deal closing." That was the figure id seen on a Merger Arbitrage Insights newsletter I subscribed to. Ninety-five percent. That number stuck in my head like a splinter I couldn't pull out. When you're sitting on a potential $40,000-plus payday from a single position, confirmation bias does terrifying things to your risk assessment. I talked through the scenario with my brother, who's a petroleum engineer in Houston, an even he figured the deal would survive. He said Chevron wouldn't have bid $53 billion without running the Exxon risk past their legal team six ways from Sunday.
February 11, 2026, 3:47 PM
The International Chamber of Commerce ruling dropped on a Tuesday afternoon. I was on a train heading back from a client meeting in midtown Manhattan when my phone exploded with alerts. The tribunal had ruled in ExxonMobil's favor. The arbitration panel determined that Chevron's acquisition of Hess did indeed trigger the pre-emption clause, giving Exxon the right to acquire Hess's 30% stake in the Stabroek Block. Chevron's entire thesis for the deal had been built around those Guyana assets. Without em, the math fell apart almost instantly. Hess shares cratered from $152 to $127 in after-hours trading that afternoon, a single-session drop of 16.4%. By the time the market opened the next morning, Hess was trading at $113.
the emotional toll of a blown trade
I sat on that NJ Transit train staring at my phone, watching the number shrink in real time, and I read something between nausea and rage. The position id built up over four years, the one I'd convinced myself was basically a certificates of deposit yielding 40% over eighteen months, was abruptly worth $27,600 less than it had been that mornin. My cost basis on those 600 shares was $64,800. At the peak right after the deal announcement, they'd been worth $103,800. Now they sat at $67,800. I'd gone from a $39,000 paper gain to a $3,000 paper gain in the span of a single afternoon. Forty percent. Gone. The numbers don't even tell the full story because I'd mentally laid out that money a hundred times. I was goin to use it for a kitchen renovation. I was going to put half into an index fund for my niece's college fund. I was gonna pay off the last $8,000 on my auto loan refinance I'd taken out in 2024. None of that was happening now.
what I actually did wrong
I pieced together my mistakes over the following weeks, and they were ugly. Mistake one: I rarely set a stop-loss on the position. Not once in four years. When you're up 50%, 60%, 70% on a stock, setting a sell order at some arbitrary threshold feels like admitting defeat. Mistake two: I let the deal announcement anchor my expectations. After October 2023, I stopped thinking of Hess as an oil company and began thinking of it as a pending check from Chevron. Every piece of freshs about the merger got filtered through that lens. When the FTC approved the deal, I saw it as confirmation. When European regulators approved, same thing. The one piece of freshs that actually mattered, the Exxon arbitration, I treated as background noise.
Mistake three, an this one honestly stings: I ignored my own rules. I'd written a personal investing policy in 2022 after the Altria fiasco. Rule number seven said, verbatim, "No single position exceeds 15% of total portfolio value." By November 2023, Hess was 22% of my portfolio. id rationalized it by telling myself the deal was de-risked, that the spread was basically money in the bank, that position sizing rules are for speculative bets, not for announced mergers with regulatory approval. Every single one of those rationalizations was a lie I told myself because the number looked too good to walk away from. I'd done the math on the capital gains tax I'd owe if I sold at the peak, approximately $6,500 at the long-term rate, an I let tax optimization override risk management. That's backward. Invariably backward.
the fallout and what I bought instead
I ultimately sold 400 of my 600 Hess shares on February 14, 2026, at $109.20 each. I maintained 200 shares as a long-term bet on the standalone company's Guyana production, which was still generating enormous cash flow regardless of the merger outcome. The $43,680 from the sale went into three places: $20,000 into a broad energy ETF to maintain some sector exposure without single-stock concentration, $15,000 into a municipal bond fund yielding 4.1% tax-free, and the remaining $8,680 into a Roth IRA conversion I'd been meaning to do for two tax years running. I zeroed in on that Roth conversion cuz sitting on cash after a loss feels like surrender. I needed to deploy the money into somethin productive immediately.
My investment advisor Greg called me the day after the ruling and said all the right things about diversification and position sizing, but I could hear the sheepishness in his voice. hed rarely once flagged the Exxon arbitration as a material risk in any of his quarterly reviews. I walked away from that relationship in March 2026 and moved my account to a flat-fee fiduciary who charges $200 a month and actually reads arbitration filings. Sometimes the cheapest advice turns out to be the most expensive. The Hess trade taught me that mergers aren't free money. They're bets on legal outcomes disguised as corporate strategy, an the house invariably has better lawyers than you do.
