What Happened?
A number of stocks jumped in the morning session after Israel and Iran launched direct strikes against each other over the weekend, the most significant test of the fragile ceasefire since April, pushing Brent crude briefly above $98 a barrel.
Energy equities followed oil higher as investors repriced the geopolitical risk premium into producer earnings forecasts.
However, the gains moderated through the session. President Trump publicly called for an "immediate ceasefire," Iran declared its initial wave of strikes complete, and WTI pulled back from overnight highs to around $91 a barrel, up just over 1%. The sector's move was a direct function of conflict escalation risk: elevated enough to lift energy stocks meaningfully, not so extreme as to tip markets into full risk-off mode.
The stock market overreacts to news, and big price drops can present good opportunities to buy high-quality stocks.

Zooming In On Solaris Energy Infrastructure (SEI)
Solaris Energy Infrastructure’s shares are extremely volatile and have had 60 moves greater than 5% over the last year. In that context, today’s move indicates the market considers this news meaningful but not something that would fundamentally change its perception of the business.
The previous big move we wrote about was 3 days ago when the stock dropped 7.8% on the news that energy stocks pulled back despite oil prices remaining structurally elevated, as WTI crude fell 1.76% to $91.40 a barrel (still more than 40% above year-ago levels).
The president said US-Iran talks were "progressing well" and reiterated he would be "honored" to meet Iran's supreme leader to make a deal, raising the possibility that Strait of Hormuz disruptions could ease faster than the market had priced. Energy stocks trade a risk premium derived from supply scarcity. If a ceasefire materializes, that premium unwinds sharply. The stronger-than-expected jobs report added a second layer: higher interest rates increase the cost of capital for exploration and production companies carrying significant debt, compressing returns on future investment. Investors reduced exposure ahead of any deal announcement rather than waiting to react.
Solaris Energy Infrastructure is up 48.3% since the beginning of the year, and at $74.51 per share, it is trading close to its 52-week high of $78.58 from May 2026. Investors who bought $1,000 worth of Solaris Energy Infrastructure’s shares 5 years ago would now be looking at an investment worth $6,984.
