Every AI data centre consumes more electricity than the buildings it replaced. That single fact has turned a scattered group of utility, electrical-equipment and power-semiconductor names into one of the most crowded themes on the AI Market Cap scanner. Five of them report inside the next sixteen days, and the numbers attached to those prints differ enormously. Treating them as one trade is the mistake.

Here is the group as the scanner currently reads it, ranked by score rather than by market cap or by how well the chart has looked:

• FSLR — First Solar. Score 94, October 29, 5 days out. Price $171.99, market cap $18.48B, implied volatility 100.5, 14-day target $260.36 (+51.4%). Thirty-six analysts at 10 strong buys, 17 buys, 8 holds and 1 sell. Short interest 13.5% of float. Earnings sentiment Positive.
• CEG — Constellation Energy. Score 80, November 9, 16 days out. Price $253.45, market cap $89.80B, implied volatility 51.2, 14-day target $322.45 (+27.2%). Twenty-five analysts at 6 strong buys, 15 buys, 4 holds. Short interest 3.7%. Sentiment Mixed.
• ETN — Eaton. Score 78, November 3, 10 days out. Price $366.11, market cap $142.16B, implied volatility 60.9, 14-day target $473.36 (+29.3%). Twenty-eight analysts at 5 strong buys, 18 buys, 4 holds, 1 sell. Short interest 2.1%. Sentiment Mixed.
• VST — Vistra. Score 70, November 6, 13 days out. Price $140.16, market cap $47.04B, implied volatility 64.1, 14-day target $181.54 (+29.5%). Twenty-three analysts at 4 strong buys, 18 buys, 0 holds, 1 sell. Short interest 3.6%. Sentiment Negative.
• MPWR — Monolithic Power Systems. Score 69, October 29, 5 days out. Price $1,140.12, market cap $56.03B, implied volatility 67.9, 14-day target $1,980.12 (+73.7%). Seventeen analysts at 3 strong buys, 13 buys, 1 hold. Short interest 5.1%. Sentiment Mixed.

Why the Scores Spread So Wide

Five names, five scores, and the reason is worth understanding because it decides which one deserves attention. The score is a sum: analyst coverage up to 25 points, buy conviction up to 25, strong buy count up to 20, implied move up to 15, earnings sentiment up to 15.

First Solar wins on almost everything. Thirty-six analysts covering a name with an $18.48B market cap is exceptional density, and 10 strong buys out of 36 ratings gives it the full 20 of the 20 strong-buy points. Its sentiment reading is Positive, worth the full 15. On top of that, a 51.4% implied 14-day range is past the 15% cap on that factor. That is how a $18.48B solar company outscores a $142.16B electrical-equipment conglomerate.

But that same 51.4% implied range and 13.5% short interest is a warning label, not a green light. A 13.5% short position in a name with 100.5 implied volatility is a book that can gap violently in either direction. The score measures how interesting the setup is, not how safe it is.

Vistra scores 70, second-lowest in the group behind Monolithic Power's 69, despite having one of the cleanest analyst books in the entire universe: 18 buys, zero holds and just one sell out of 23 ratings. That is 95.7% bullish. The reason it loses points is the sentiment reading, which is Negative, worth zero out of fifteen. Vistra has not consistently beaten estimates. When a name carries that label, the market is not paying for a beat so much as for evidence that the misses have stopped.

The Timing Cluster Nobody Should Trade Blindly

October 29 is the collision point. First Solar and Monolithic Power both report that day, five days from now. They are not the same trade despite the shared date. First Solar is a solar manufacturer whose earnings depend on utility-scale project economics and interconnection queues. Monolithic Power is a power-semiconductor supplier whose results track how much power-management content is being designed into AI server platforms. Shared print date, shared theme, entirely different revenue models and entirely different failure modes.

Constellation and Vistra are both nuclear-weighted generators with direct, long-dated contracts to sell power into data-centre demand. They report three days apart, on November 6 and November 9. The interesting structure here is sequential: Vistra prints first, and Constellation will have its number to trade against three days later. When two names in the same sub-sector print three days apart, the first print moves the second one.

Eaton sits in the middle and is the least thematic of the five. It is an electrical-equipment company with a 10-day window, a $142.16B market cap and the most ordinary implied move in the group at 60.9. Its 29.3% implied 14-day range is the tightest here except Constellation's 27.2%. Sometimes the right answer in a crowded theme is the name nobody is writing about.

How To Size a Position Across This Group

The practical problem with owning more than one of these is that they are not five independent bets. First Solar, Monolithic Power and Eaton all sell into the same AI capital expenditure cycle. Constellation and Vistra both depend on the same power-demand assumption. If the AI buildout pace disappoints, all five fall together, and the ones with the widest implied ranges fall furthest. That correlation is why a score-94 name with a 51.4% implied range is not a safer choice than a score-70 name with a 29.5% one.

Read the implied ranges as the sizing instruction. First Solar at 51.4% and Monolithic Power at 73.7% are wide. Eaton at 29.3% and Constellation at 27.2% are the tightest. Vistra at 29.5% is moderate but carries a Negative sentiment reading and only 23 ratings behind Monolithic Power's 17.

There is also a tape caveat that matters this week. The whole semiconductor complex was repriced on October 22 when Lam Research commentary about clean-room capacity and supply constraints landed, taking the SOX index down 6.72% and roughly $200 billion out of thirty companies. Applied Materials fell 8.16% that session, KLAC fell 9.55%. Monolithic Power is a semiconductor supplier and fell 5.84% over the past week. First Solar fell 2.04% on October 22 and has gone essentially nowhere since. If the AI power trade is being sold on equipment-cycle concerns, then the prints in this group will be read against that, not on their own merits.

What To Watch Between Now and the Prints

• October 29 is the key date. Two of the five report that day. Watch whether the market treats them as one trade or two — if Monolithic Power's implied range expands into the print while First Solar's holds, the market is separating AI hardware from AI power generation.
• Watch the October 29 reaction for Constellation and Vistra. Their numbers arrive November 6 and November 9 with an AI-equipment print already in the books.
• Track First Solar's short interest, not its analyst ratings. At 13.5% of float with 100.5 implied volatility, that combination produces moves that are not about fundamentals.
• Eaton is the low-volatility expression. If you want the AI power theme with a 29.3% implied range instead of a 51.4% one, this is where it lives.

Five AI power names print inside sixteen days and the scanner scores them from 69 to 94. The spread comes from real measurable differences in coverage, conviction, sentiment and priced-in movement, not from noise. First Solar scores highest and carries the heaviest short interest, while Monolithic Power carries the widest implied range. Vistra scores 70, second-lowest, and holds the cleanest analyst book with the worst sentiment reading. Eaton is the least interesting story and probably the most manageable position. Rank them for your own risk, not for the feed.
