A Deep Dive Into His Last ~300 Replies

Topics covered: Serenity’s background, Supply Chain Chokepoint Theory, detailed theses on AXTI 0.00%↑ $SIVE AAOI 0.00%↑ and other photonics/CPO plays, Nvidia’s optical playbook, institutional rotation, macro/geopolitical views (Iran, rare earths), neocloud/energy analysis, analytical process, and future predictions for 2027–2028.

Summary of his key stocks -

A note on Serenity and the noise around him: Any analyst with strong public conviction attracts criticism, and Serenity is no exception. Accusations of pumping small cap names to a large audience. That said, his track record includes several well-documented calls that played out on fundamentals: identifying the photonics rotation before institutions arrived, and mapping $AXTI’s chokepoint value long before it became consensus. The smartest thing any investor can do is study the reasoning behind someone’s ideas, stress-test it against your own research, absorb what strengthens your process, and simply move past what doesn’t. Blind conviction in anyone is a mistake - but so is reflexively dismissing good thinking because of noise.

Who Is Serenity?

Serenity (@aleabitoreddit) is a former Reddit WallStreetBets trader who migrated to X and has rapidly built a 127,000+ follower base with what he calls “S tier research” distributed for free. His bio describes him as an AI/Semi Supply Chain Analyst and former RISC-V FDN and AI research scientist “now trading unknown bottlenecks.” His methodology is distinctive — he does not just pick stocks from headlines. He reverse-engineers entire supply chains, finds chokepoints nobody else is watching, and then constructs asymmetric trades around them before institutional rotation arrives. He’s extraordinarily vocal in replies, often doing more analysis in his thread responses than most paid analysts do in formal reports. His total portfolio return at one point in the review period flashed +501.24% YTD, though he noted more recently that performance has pulled back from peak (”Not doing so well anymore”). He typically runs ~1.4x margin, concentrating into a small set of high-conviction thesis-driven names.

His Core Investment Philosophy

Supply Chain Chokepoint Theory — The Central Framework

The single most defining thread throughout all of Serenity’s tweets is what could be called his “Chokepoint Theory.” He does not invest in the big, obvious beneficiaries (Nvidia, Microsoft, Meta, Google) but instead hunts for the narrow, often-overlooked nodes in the supply chain that the big companies *must* depend on — nodes so concentrated that if they fail or get controlled, the entire buildout fails. He uses a powerful analogy repeatedly: The Strait of AXTI - Just as 20% of global oil passes through the Strait of Hormuz, he argues that AXT Inc. ( AXTI 0.00%↑ ) controls a similarly critical chokepoint for photonics — specifically InP (Indium Phosphide) substrate creation. He notes that AXTI “vertically integrates 4 different chokepoints under 1 supply chain,” making it unlike anything else in the West. He maps chokepoints across several layers:

• Chokepoint 1 (raw materials): $AXTI for InP substrates / gallium, indium, arsenic. He mentions $VNP as a partial Western alternative but nothing on the same scale.

• Chokepoint 2 (pBN Crucibles): Shin-Etsu Chemical is mentioned as a possible player.

• Substrate processing: He found what he describes as a brand-new “monopoly/duopoly” company (unnamed, extremely obscure) in the upstream InP substrate creation process — “without it I think the photonics buildout goes down.” He believes the U.S. and companies like $COHR will eventually embark on a “vertical integration buying spree or capacity securing spree” because of how dangerously dependent the AI photonics buildout is on these chokepoints. ---

Top Stock Picks — The Conviction Portfolio

1. $AXTI (AXT Inc.) — The Crown Jewel Chokepoint

Serenity describes AXTI as “basically the entire photonics supply chain.” He believes it’s a monopolistic chokepoint over the AI industry specifically for InP substrate creation and says it should “hold current levels or keep growing like a mini $SNDK bottleneck/price hiking gets severe.” He responds to critics harshly: “Majority of folks have 0 clue what they’re talking about. Samsung Foundry or $LITE InP fab are completely different parts of the supply chain.” He holds it despite 15–25% daily swings. He floats the thesis that if a figure like Martin Shkreli joined the board, AXTI could be a $10B+ company by pricing its monopoly appropriately. At current prices he calls it “fairly valued” but is “personally holding.”

2. $SIVE (Sivers Semiconductors) — His Highest Conviction Emerging Play

$SIVE is the stock he talks about most expansively and emotionally. He argues it is “grossly mispriced” at roughly $290m market cap because it controls the CW (continuous wave) laser light source chokepoint for the next generation of Co-Packaged Optics (CPO) — a field that will explode 2027–2028. He outlines his acquisition thesis explicitly: “A competitor to $MRVL like $AVGO can just buy Sivers outright and their near-medium term photonics roadmap... At ~$290m... if it gets any cheaper.” He ran an AI simulation (Gemini) and it confirmed his logic verbatim. He places Sivers in the acquisition chain: “It goes $SIVE → Win → $POET → Celestial → $MRVL basically. You just buy out the upstream light source and Marvell’s supply chain gets controlled for dirt cheap.” His financial projections for $SIVE:

• 2026/2027 expectations: 0 revenue, -$50m loss

• 2028 expectations: $500m revenue

• 2029 expectations: $1B revenue

• He calls this “massive TAM” He bought ~0.5%–1% of $SIVE. He acknowledges short−term risk (”highvolatility”) but says:” $SIVE as a company. He acknowledges the short-term risk (”high volatility”) but has high confidence.” When meme-stock accusations come, he fires back: “All the retail and news ‘labelled meme stocks’ for my picks ended up becoming billion dollar companies like $AXTI.” He notes NVIDIA’s $2B investment into Marvell — for “joint silicon photonics work” — validates the Celestial AI CPO roadmap, which depends heavily on $SIVE as the light source.

3. $AAOI (Applied Optoelectronics Inc.) — The Transceiver Play

He describes AAOI’s supply chain as “laser → design → assembly → sells the transceiver. They have the whole supply chain.” He also notes they’re building ELSFPs (external light sources) so they’re entering the CPO side too. He puts AAOI in his “fastest compounds” list with a “10x revenue ramp from optical transceivers H2 2027.” He bought “a decent amount of $AAOI at ~$84 just now, $6.6B MC feels way too cheap for me, especially with their new $500m warchest.” He says: “I have high confidence in $AAOI in 1 year time. Just this time period has extreme volatility.” On the Herb Greenberg short report on AXTI/AAOI, he dismisses it: “You must be new here with $AXTI if you haven’t experienced 15–25% daily drawdowns.”

4. $MRVL (Marvell Technology) — Long-Term Core

He calls $MRVL “a really good long term long.” He believes Nvidia’s $2B investment validates Marvell and Celestial AI’s optical fabric CPO roadmap. He notes Marvell can “buy 10–20% of $SIVE for $30m and secure their billion dollar CPO program.” He is excited by the NVDA-MRVL deal: “Yeah $NVDA is really pushing hard on their CPO architectural roadmap and locking in all the biggest players into their standards.”

5. $RPI (Raspberry Pi Holdings PLC) — The Hoarding Play

He called this one early — in February — as a “Fun Trade Idea: Long $RPI (Raspberry Pi). Reason: Openclaw / Picoclaw / Nanobot + Hoarding.” The thesis: while people were hoarding Apple Mac Minis, $AAPL is a $3.7T company and product hoarding won’t move the needle. But $RPI is tiny and demand spikes are massive at scale. He waited through noise while analysts called it “meme stock territory” (comparing it to $GME). He notes: “Yeah... got tired of all the noise so just waited for earnings to validate my thesis.” On March 31, $RPI posted +44.76% in a single day and then +27.43% the next session, with analysts raising 2026 forecasts to $511m. He projected 55% revenue growth when analysts were saying 14% — actual came in at 58%. He now projects “11–13x p/e projections for 2027 and ~19–22x for 2026.”

6. $AEHR (Aehr Test Systems) — Testing Chokepoint

He categorizes AEHR as part of the photonics supply chain: “AEHR does testing.” He notes the company received “new qualification orders from a leading optical transceiver company.” He believes it’s in the “early $AAOI stage where it’s getting tested by major hyperscaler supply chains for optical transceivers/silicon photonics. Before the mass volume inflection point that may be at any time.”

7. $COHR (Coherent Corp.) and $LITE (Lumentum) — Photonics Ecosystem

Both are beneficiaries of the NVDA $2B optical investment. He notes $COHR is “trying to vertically integrate up” — doing so at the InP substrate level, but “not feedstock/refinery level/processing yet.” He sees overlap with $AXTI at “chokepoint 4” but sees them working their way up.

8. CPO Landscape Overview (Mirae Analyst Note) — His Full Map

He published and annotated the following CPO industry landscape:

• Scale-Across (CPO ASIC): $AVGO, $MRVL

• Optical Transceiver: $COHR, $LITE, Innolight

• DSP/PAM4: $AVGO, $MRVL

• Coherent DCI: $CIEN, $NOK

• OCS Equipment: iPronics, Polatis

• Optical Cable/Fiber: $GLW, Prysmian, Furukawa

• HCF: $LITE, OFS

• Light Source/ELS: $SIVE (Sivers), $AAOI, POET, Celestial AI (unlisted) He notes he was “confused” by the Mirae list missing several key ELS names and said he’d do a TLDR translation on his main account. ---

The $NVDA Playbook Thesis — His Framework for Understanding the Next Move

One of his most-shared threads explains why the market is “missing the implications” of Nvidia’s $2B optical investments. He writes: “$2B into $COHR for optical. $2B into $LITE for optical. And $2B into $MRVL for optical today. Nvidia did this exact same playbook last year.” Last year, he explains, Nvidia secured all EML (Electro-Absorption Modulated Laser) capacity before there was a massive supply shock. Now they’re doing the same with next-gen optical interconnects. His conclusion: companies holding critical CPO supply chain positions like $SIVE are about to experience the same capacity lock-in dynamics. His investment slogan: “This is the exact playbook $NVDA did securing all the EML capacity before there was a massive supply shock for the rest of the hyperscalers. That’s why I’ve been sounding the alarm with $SIVE in the next chokepoint.”

Macro Views and Market Stance

Overall Market: Bearish on the Broad Market, But Bullish on Select Names

He states clearly: “Overall I’m bearish on markets as a whole. However there will be clear individual winners. It’s a stock pickers market right now.” He adds: “Let’s just say even if $SPY, $MSFT, $AMZN crashes another 20% I expect $AAOI to outperform the market.” He was on margin (up to ~1.4x) but wound down to 0 margin on the Iran conflict escalation: “No, Iran conflict and Trump have too much uncertainty, and I’d rather not leverage on the way down just in case it keeps dropping.”

Iran War — A Major Focus

This is a recurring macro theme. He watches the Middle East conflict closely as a key market catalyst in both directions. He built a “Doomsday ETF” for the war scenario:

• 25% $FAZ (3x Short Financial) — “Private Market liquidity play on Middle Eastern capital abandoning private markets if all their oil fields get blown apart”

• 25% $GUSH (3x Long Oil)

• 20% $SLCID Short

• 10% $SQQQ

• 10% $UVIX

• 10% $NVDA Puts He explains: “Nvidia is still $4.1T, in a massive liquidity crunch and energy crisis, it can fall a lot, lot further if Iran blows everything around it up. Still think US is looking for an off ramp/TACO but Israel is looking to keep things going.” He also responded to a query about Trump ending the war: “The market are missing the implications from $NVDA investing... US indexes have shot up ON, but KOSPI (-3.55%) and Nikkei (-.85%) trading live are still down.” On Iran de-escalation news: “Got trolled by one of the recent media pulling old quotes. This was new one.” He commented on the rare earths policy angle: “Can we please... just secure our rare earths supply chains first before we do this? How are we able to spend billions on glass towers in Miami? But not subsidize all our most important AI, Robotics, and Space rare earth upstream supply chains... That are entirely dependent on [China].”

Broader Market Rotation Theory

He articulates what he believes is the institutional rotation happening: “I think I nailed the institutional bottleneck rotation: → Caught the tail end of memory name rise with $SNDK, Samsung, SK Hynix, $MU → Frontran institutions with photonics with names like $AAOI, $AXTI $LITE, $COHR. → Doing it again now by adding heavily toward SiPh, ELS.” He believes “external light sources” is the next category institutional investors rotate into after optical transceivers.

On Hyperscaler CAPEX

He notes the hyperscaler context: “1. Hyperscalers (ORCL, $META, $AMZN): They’re spending more than they have with profit ( GOOGL is the rare exception, and $AAPL isn’t really spending much relatively). So markets are worried less worried it’s translating into [demand].” He believes hyperscaler capex projections being cut 50% still leaves demand scenarios for photonics names “still going to do well.” \---

Neocloud and Data Center Views

On Nebius ( NBIS 0.00%↑ ), Iris Energy ( IREN 0.00%↑ ), CoreWeave ( CRWV 0.00%↑ )

He analyzed the three major neocloud players: “One of them ends up as the next AWS in 5 years. My guess it’s Nebius.” He elaborated: “It’s not winner takes all (DigitalOcean is there with Amazon), but there’s clearly superior structures and likely winners.” $IREN: He was long $IREN previously but flipped bearish due to the $6B ATM (At-The-Money share offering): “$6,000,000,000 dilution and sales into the open market for $IREN is not ‘noise.’” He explains the mechanism: “If the marketcap is $11 Billion and they’re selling up to $6,000,000,000 worth of new shares against you in the open market — I would not go long until the ATM is finished.” He says he’d consider “flipping long again” after the ATM is exhausted. He also called out the executive SBC (stock-based compensation) problem: “There’s something called SBC where $IREN executives can issue more shares to themselves. Take a look at $SNAP, the company awards employees $1B+ every year while stock prices keep dropping.” $CRWV (CoreWeave): “If you have to think about almost not sinking for $CRWV... there’s probably better longs out there in the market, just saying.”

His Views on Specific Dynamics and Companies

On $MP (MP Materials) — Rare Earths

“Yes $MP is paramount to national security. Again China has weaponized Rare Earths against us. It’s incredibly stupid for FT and other news outlets to go and get rile up the US population... At the US government spending to secure our supply chains??? So we don’t rely on Russia.” He considers $MP a growing national security play.

On LNG/LNG/ LNG/GLNG — Energy War Plays

“Honestly... the most obvious ideas like long $LNG. Or going long on $CVXO. Are probably the best ones instead of contrarian longs in Wartime? Especially with low 18–30 IV, this would have easily been a few hundred percent gain by now.” He called $LNG a “good pick” when another user mentioned it. He bought $LNG and $CVX as obvious energy war plays, showing +52.74% YTD for $LNG and +35.44% for $CVX in charts he shared.

On $NEXT (NextDecade) — LNG Long-Term

“Extremely solid multi-year long (eg. 3–5 years) for $NEXT, especially when capacity is sold out already. LNG production is first half of 2027 though? Though I do think the sector as a whole will get attention. The main beneficiaries of Iran are the LNG exporters like $LNG now.”

On $VCX (Fundrise Innovation Fund) — Strong Warning

“Warning about $VCX. A very popular ETF with weighting toward (Anthropic, Databricks, OpenAI, Anduril, and SpaceX).” The fund dropped ~36.35% in a single day in his screenshot. He had been warning about it earlier.

On $ARM

He lists ARM as one of his “fastest compound” plays: “$ARM — 5x revenue growth from their new AI CPU.” He also noted that “tbh I like all of the names I’ve mentioned. Win Semi and $ARM were the newest ones out of the bunch.”

Win Semi

He mentions Win Semi as a recent add: “Nope, just Win Semi so far” (when asked about second long position). He also groups it with his personal preferences: “You can replace $MU / $SNDK with Sk Hynix. Or replace $COHR with $LITE. I’m just saying my personal preferences in what I expect to outperform.”

On $ETH (Ethereum)

“So I was bearish on Ethereum earlier at $3–4K. I’m actually bullish on $ETH again around $1.6K–2.2K. That said, I’m slightly bearish overall on the market due to escalating Iran tensions, and Ethereum typically isn’t the flight to safety asset.”

$COIN (Coinbase)

In a subscriber thread, he was “just disrupting $COIN’s business model on a Tuesday?” — referring to a discussion about free L2 spot DEX platforms. He asked followers if there are “completely free L2 Spot DEXs out there for Takers? Like Lighter, but available in the US.” He considered building one — “I feel like a open source/free l2 spot DEX would be a fun weekend project to panic coinbase/robinhood.”

On AI and Personalized Medicine

He briefly touches AI medicine: “Personalized AI medicine will likely be huge. Nobody wants to die early. If you can do it for one person... the next generational company will figure out how to automate/commoditize it and scale it to the rest of the world.” He was referencing the story of a CEO who used ChatGPT in his cancer fight.

How He Thinks — Analytical Process

The Supply Chain Map First

He builds detailed supply chain maps before investing. He cited a CPO value chain from an academic Korean source (he notes he needs to “translate” it) and created his own chart of the “Strait of $AXTI” mapping the photonics chokepoints visually with imagery. He is clearly doing proprietary original research — “Yep, I spent a lot of time making this on the chart.”

Thesis Validation Over Noise

He explicitly says he waits for earnings to validate his thesis rather than trading on noise: “Yeah... got tired of all the noise so just waited for earnings to validate my thesis. Now $RPI is trading at roughly 2 fwd p/s as a fabless AI hardware company.” On $SIVE criticism: “It’s always when you’re earliest to something that you get the most criticism / doubt.”

Contrarian When Early

He took a great deal of abuse on $RPI — journalists called it a “meme stock,” “GME territory.” His response: “Just frustrating everyone on X and social media called it a ‘meme stock.’ When I called fundamental changes on $RPI and got it right. Now they’re all silent, and then just updated their models on an AI fabless stock trading at fwd 19 P/E.”

Thinking in Second and Third Order Effects

He regularly reframes conversations with systems-level thinking: “This is vastly underestimating second, third, fourth order effects of supply chains and the energy crisis. If Iran blows up a lot of oil fields in UAE and the Middle East and cause[s]...” He also commented: “You’d be surprised. They probably didn’t look at supply chain vulnerabilities after we started picking a fight with Canada. Lot of third, fourth, fifth order effects or very niche chokepoints aren’t completely mapped out.”

His Predictions for the Future

1. The CPO (Co-Packaged Optics) era is next — he believes the 2027–2028 window is when photonics transitions from pluggables to CPO at scale, which will create enormous demand for external light sources ($SIVE, $AAOI, $POET, Celestial AI).

2. Vertical integration M&A wave — he expects Broadcom (AVGO),Marvell(AVGO), Marvell ( AVGO),Marvell(MRVL), or a similar player to acquire Sivers ($SIVE) outright for ~$280–350m before the CPO ramp begins.

3. Institutional rotation — institutions will rotate from HBM/memory (Phase 1) → optical transceivers (Phase 2) → external light sources/SiPh (Phase 3, now beginning).

4. Rare earth crisis as a policy forcing function — if China restricts gallium/indium, the US will be forced to accelerate domestic chokepoint investment, benefiting AXTI.

5. Nebius wins the neocloud race — he bets $NBIS becomes the AWS-equivalent of the current neocloud boom.

6. $RPI repricing continues — analysts still underestimating the OpenClaw/AI/hoarding demand surge.

7. Photonics names hold better than megacap — even if $SPY crashes another 20%, he expects $AAOI and other photonics names to outperform.

Personality and Style Notes

Serenity is combative but self-aware. He readily admits mistakes (”Yeah, I underestimated Trump a bit on Iran”) and updates his thesis with new data. He is dismissive of surface-level analysis and gets frustrated when journalists or retail investors engage with his stocks without understanding the supply chain context. He is clearly enjoying the intellectual challenge — he mentions “shower thoughts” as serious analytical frameworks, uses AI (Gemini) to pressure-test his theses, and discusses being approached by industry executives about $SIVE after he published his original post. His style is fundamentals-first but with deep derivatives/volatility awareness — he mapped Jane Street’s algorithms in his $EWY trade and regularly thinks about option chain dynamics. He self-describes the range of his analysis as covering: “macro, micro/company-level, and derivatives technicals, then puts it all together in one easily understandable package.” Despite his 127K following and institutional-quality research, he remains genuinely retail in spirit — he’s not interested in board positions, he warns followers about dilution mechanics for many stocks.
