The stock market has been acting like a teenager with a caffeine habit lately—lots of energy, plenty of mood swings, and a total obsession with the next big thing. Honestly, if you blinked on Friday, you might have missed a massive shift in how investors are treating the tech and energy sectors. It wasn't just a quiet drift into the weekend; it was a full-on reshuffling of the deck.
We're seeing the biggest stock movers today hitting the tape with some serious force. While the S&P 500 stayed relatively flat, slipping just about 0.06% to close near 6,940, the action underneath the surface was anything but calm. We’ve got space stocks hitting the moon (literally), chipmakers riding a wave of insider confidence, and some energy plays getting absolutely hammered by a shift in White House policy.
The Chip Giants: Inside Moves and Global Deals
You’ve gotta look at Micron Technology (MU). It jumped over 7% basically because one person—director Teyin Liu—decided to drop $7.8 million on shares. When an insider buys that much of their own company's stock at prices around $337, people notice. It’s the ultimate "put your money where your mouth is" move.
But it wasn’t just Micron. The whole semiconductor space is vibrating right now because of a massive $250 billion trade deal between the U.S. and Taiwan. Super Micro Computer (SMCI) surged 11% on the back of this. Think about that for a second. That is a massive chunk of value added in a single session. This deal is basically a promise to keep the AI machines fed with chips, and in a market that is terrified of an "AI bubble," this news acted like a giant safety net.
Gainers and Losers: The Friday Scorecard
It’s always a mixed bag, but some of these percentage moves are wild.
- ImmunityBio (IBRX): This one was a beast. It soared nearly 40%. They put out some strong guidance for their bladder-cancer drug, and the market reacted like they’d found a gold mine.
- AST SpaceMobile (ASTS): Up over 14%. Why? They locked in a prime government defense contract. In the stock world, "government contract" is often code for "guaranteed revenue," and investors love that.
- Constellation Energy (CEG): This was the heartbreak of the day, dropping nearly 10%.
- Vistra (VST): Also felt the pain, sliding over 7%.
Why the Energy Sector Just Got Punched
You might be wondering why power producers like Constellation and Vistra took such a nosedive. It feels counterintuitive, right? Everyone needs power for AI data centers. Well, the White House threw a curveball. They proposed an emergency power auction. Basically, instead of tech companies getting to lock in exclusive, long-term deals with these power plants, they might have to bid for them in a more competitive, regulated way.
Investors hate uncertainty. The idea that the government might step in and mess with how these "AI power deals" are structured sent people running for the exits. It’s a classic case of policy risk overshadowing a solid business model.
The Bank Earnings "Meh"
We're right in the thick of earnings season, and the banks are giving us a "sorta-good, sorta-bad" vibe. PNC Financial (PNC) had a great day, jumping almost 4% after beating expectations. They’re seeing more money from interest payments and dealmaking. On the flip side, Regions Financial fell about 2.6%.
It’s a tale of two cities. Or, more accurately, a tale of who managed their balance sheet better when rates started shifting. J.B. Hunt (JBHT) also slipped about 1% because, frankly, they didn't move as many boxes as people hoped. If the trucks aren't moving, the economy usually isn't humming as loudly as we'd like.

Looking Beyond the Noise
What’s really happening here is a market trying to find its footing for the rest of 2026. We’ve got people like Doug Beath at Wells Fargo warning about volatility, and they aren't wrong. Between geopolitical tensions—like those protests in Iran affecting oil prices—and the "who's the next Fed Chair" guessing game, there's plenty to be nervous about.
Gold is down a bit, and Treasury yields are creeping up. The 10-year Treasury yield is sitting around 4.22%. That matters because when yields go up, it usually puts a lid on how high tech stocks can fly. It makes the "risk-free" return of a bond look a lot more attractive than a volatile stock.
Common Misconceptions About Today's Moves
- "The AI Bubble is Bursting": Not really. Look at SMCI and MU. The demand is there, and the government is literally signing deals to ensure the supply is there too. It's more of a rotation than a burst.
- "High Rates Kill All Tech": Some tech is actually thriving because they have zero debt and mountains of cash.
- "Energy Stocks are Done": The drop in CEG and VST is a price adjustment for a new regulatory reality, not a sign that we don't need electricity anymore.
What You Should Actually Do Now
Don't just stare at the tickers. If you're looking at the biggest stock movers today and feeling like you missed out, take a breath. Momentum is a powerful drug, but chasing a 40% gain in IBRX after the move has already happened is a great way to lose money.
Keep an eye on the 10-year yield. If it keeps climbing toward 4.5%, those tech gains might start to evaporate. Watch the energy auction news. If the government softens its stance on those power deals, CEG and VST might look like absolute bargains at these lower prices.
Next week is huge. We’ve got United Airlines, 3M, and Intel reporting. That’s going to tell us if the "real" economy—the one where people fly on planes and use Scotch tape—is as strong as the "AI" economy everyone keeps talking about.
Check your portfolio for "concentration risk." If you're 90% in chips and space stocks, today was a great day, but you're one regulatory tweak away from a bad week. Diversify into those boring "durable" businesses that Adam Spatacco and other analysts keep whispering about. They might not move 14% in a day, but they also won't keep you awake at night when the White House decides to change the rules of the game.
