What changed in the book, and why it matters — a plain-English daily read on how Serenity's reconstructed positions shift: new names, rising conviction, quiet exits.
On a quiet day for new calls, Serenity — the stock-picker whose reconstructed portfolio this site tracks — put the spotlight on a single name: Rocket Lab (RKLB). He drew attention to a fresh $397 million contract awarded to the company by the US Space Force. According to his note, the deal covers building out Rocket Lab's "Flatellite" satellite line and launching them aboard Neutron, the company'…
Serenity, the stock-picker whose reconstructed views this site tracks, spent Tuesday reinforcing one of his highest-conviction bets: that the memory-chip industry is heading into a multi-year, AI-driven supply crunch rather than the oversupply glut some skeptics still forecast. His focus was a report, attributed to trade outlet Digitimes citing industry sources, indicating that the largest memory…
It was a quiet, reflective day from Serenity, the stock-picker known for front-running the AI photonics buildout by hunting the small upstream suppliers — lasers, substrates and epiwafers — that the largest chipmakers and cloud operators quietly depend on. Rather than his usual supply-chain deep dives, his only comment today turned to the macro backdrop. Serenity flagged reports that the United S…
Earnings season handed Serenity, the stock-picker tracked here for his bet on the obscure upstream suppliers feeding the AI optical buildout, a batch of results he read as broad validation of his thesis. His method is to treat hyperscaler spending as a signal of where demand lands, then buy the smallest "chokepoint" supplier — a hard-to-replace vendor with few substitutes — the giants quietly depe…
Serenity, the stock-picker who front-runs the AI buildout by buying the obscure upstream suppliers that feed NVIDIA's roadmap, spent Thursday parsing an earnings call and marveling at a whipsaw market day. FORM's CPO signal. His most substantive read came from FormFactor (FORM), a maker of wafer-testing and probe-card equipment that Serenity treats as a bottleneck in the ramp of high-bandwidth me…
Serenity, the stock-picker who back-maps the AI buildout to find the small upstream suppliers big chipmakers quietly depend on, used a turbulent trading day to reframe a broad slide as short-term deleveraging rather than a break in his thesis. A selloff he views as mechanical, not fundamental His central argument today was that a sharp, correlated drop across his themes was driven by margined tr…
Serenity, the stock-picker whose reconstructed portfolio this site tracks, kept his commentary brief but pointed on Sunday, weighing in on a pair of headlines that speak to the scale of money now sloshing through the AI infrastructure buildout. ## Nvidia's circular financing The bigger of the two items concerned NVIDIA (NVDA), the dominant designer of the graphics processors that power AI traini…
A relatively quiet day for Serenity, the small-cap stock-picker whose portfolio is built almost entirely around the optical plumbing of the AI buildout. His single note today unpacked a recent podcast appearance ("Market Insights: Photonics & AI") by the chief executive of Sivers (SIVE), the tiny Sweden-listed maker of indium-phosphide continuous-wave lasers that sits at the center of his book. In…
Serenity, the stock-picker known for front-running the AI buildout by buying the obscure upstream suppliers — lasers, substrates, memory — that the big names quietly depend on, spent Thursday parsing fresh earnings and news for confirmation of his core theses. Tesla as a supply-chain telegraph. Serenity combed through Tesla's (TSLA) earnings transcripts, flagging Elon Musk's repeated, high-convic…
Serenity, the small-cap stock-picker who builds his book by hunting the obscure upstream suppliers feeding the AI buildout, spent Tuesday chronicling one of the strongest single-session rallies his portfolio has seen this year. A broad AI snapback. He opened the day noting that memory shares tied to Japan's Kioxia jumped more than 17% and Samsung rose over 6%, while optical, neocloud and chip nam…
## A supply-chain deep dive, then a Neocloud rally Serenity — the small-cap stock-picker who front-runs the AI buildout by hunting the obscure upstream suppliers that Nvidia and the hyperscalers quietly depend on — spent Monday split between granular supply-chain research and a sharp move across the AI cloud names he tracks closely. ### Mapping the passive-component and substrate bottlenecks Hi…
It was a quiet Sunday for Serenity, the stock-picker who builds his portfolio by back-mapping the AI buildout to its most obscure upstream suppliers. He surfaced only a single, brief observation today — and named no tickers — but the note still fit neatly into the broader thesis he has been developing for months. Serenity's remark centered on the idea that leading frontier AI models appear to be …
It was a reflective, defensive Saturday for Serenity, the stock-picker whose approach centers on buying the small, upstream "chokepoint" suppliers — the lasers, substrates and packaging tools — that feed the broader AI buildout. Rather than announcing trades, he spent the day answering critics and disclosing the pain in his own book. Cultural divide, and a candid drawdown number. Serenity contras…
Serenity, the small-cap-focused stock picker whose reconstructed portfolio this site tracks, spent Friday returning to one of his highest-conviction stories: the idea that AI is driving a structural, multi-year shortage in computer memory rather than a passing price blip. The trigger was a research call from a Meritz Securities analyst arguing that the market is badly misreading the semiconductor…
Serenity, the small-cap stock-picker whose reconstructed portfolio this site tracks, spent Tuesday focused on two things: a blowout quarter from one of his higher-conviction holdings, and fresh data points feeding his long-running memory-shortage thesis. ## AEHR's qualification-to-volume moment The day's headline event was Aehr Test Systems (AEHR), which jumped more than 36% following its earnin…
Serenity, the stock-picker whose reconstructed portfolio this site tracks, spent Tuesday parsing a round of public reassurances from NVIDIA chief Jensen Huang — comments the market read as an attempt to quash reports of slipping product timelines. For readers new to the name, NVIDIA (NVDA) is the dominant designer of AI accelerator chips, and it sits at the center of Serenity's entire investing m…
Serenity, the small-cap-focused stock picker who back-maps the AI supply chain to find the obscure upstream suppliers that NVIDIA and the hyperscalers depend on, spent today running through a long consolidated list of data points he found notable. He framed it less as reporting and more as sharing the raw intelligence he sifts each day. Several items reinforced his standing theses. Memory supercy…
A quiet, reflective day from Serenity, the stock-picker whose reconstructed views this site tracks. Rather than adding to positions or laying out fresh supply-chain theses, he offered two loosely connected observations — one on the AI incumbents, one a self-deprecating aside about where the real returns have been hiding. A contrarian nod to OpenAI. Serenity floated the idea that Sam Altman and Op…
Serenity, the stock-picker whose reconstructed views this site tracks, spent Friday pushing back against what he framed as an overblown selloff in the AI optical-interconnect space — the corner of the market he cares about most. "Nothing has changed." His day began with a defense of the photonics complex, arguing that two catalysts behind the recent weakness — a Bloomberg report on Meta's compute…
Serenity, the stock-picker who back-maps the AI buildout to find the small upstream suppliers the giants quietly depend on, spent Thursday connecting a leaked corporate memo to two of his core positions and flagging a notable insider signal in his top holding. Meta memo lights up the memory and optics theses. The day's catalyst was a published internal memo from Meta Platforms (META), the social-…
A noisy macro tape gave Serenity, the stock-picker tracked here, plenty to react to on Tuesday, but his message was one of steadiness: hold the upstream chokepoints through the volatility. Space valuations reset higher. Serenity flagged a report that Blue Origin is raising roughly $10 billion at a $130 billion valuation, arguing the private-market anchor is good news for listed space names by com…
Serenity spent Tuesday pushing back against what he characterized as one of the sloppiest thematic selloffs of the year, as a wide swath of AI-linked names dropped anywhere from 4% to double digits. The selloff and his read. He tied the drop to three catalysts he considers hollow: a Meta (META) compute story he says contained nothing new, and two separate reports of delays to co-packaged optics —…
Serenity, the small-cap stock-picker whose reconstructed positions are tracked on this site, spent Monday pointing to a fresh Nomura research report that he reads as broad confirmation of his dominant investment theme: the upstream materials that feed AI photonics. At the center of that theme is indium phosphide, or InP — the compound-semiconductor material used to make the high-speed lasers and …
On a quiet US market holiday, the stock-picker known as Serenity stepped away from his usual supply-chain deep-dives and offered a broad, provocative thought instead of a trade. A macro musing, not a position Serenity framed himself as "bearish on humans" — a deliberately blunt way of arguing that cheap, mass-produced humanoid robots could displace large swaths of human labor. His rough marker w…
Most of Serenity's day was spent pushing back on what he described as a wave of misinformation around Meta Platforms (META), the social-media and AI giant that anchors the mega-cap sleeve of his portfolio. Meta functions in his framework as a profitable "hyperscaler" — a cash-generative internet company whose heavy AI spending, in his view, effectively bankrolls the smaller upstream semiconductor …
The clear event of the day for Serenity, the stock-picker whose reconstructed views this site tracks, was fresh capital hitting his single largest and highest-conviction holding. ## Sivers funds the scale-up Sivers (SIVE), the tiny Swedish maker of indium-phosphide (InP) lasers that Serenity treats as the core of his entire portfolio, closed an upsized institutional round of 700 million SEK. InP…
Today was less about trades and more about reflection. Serenity, the stock-picker known for back-mapping the AI supply chain to find obscure upstream "chokepoints" — critical suppliers with few substitutes — marked crossing 900,000 followers with a long, unusually personal note about how much harder the platform has become to navigate at scale. The post named no new positions, but it touched seve…
Serenity, the deep-value stock-picker who back-maps the AI buildout to its most obscure upstream suppliers, stepped back from the weeds today for a wide-angle reflection rather than a new trade. In an early-morning post he argued that the 2020-2030 stretch may be the most consequential decade for technology in human history, and that simply being an active investor through it feels remarkable. The…
A quiet day for fresh trade ideas, with Serenity — the stock-picker who builds his portfolio by back-mapping the AI supply chain and buying the small upstream chokepoint suppliers that the hyperscalers and Nvidia quietly depend on — turning his attention to a single macro story rather than any individual name. The catalyst was a Wall Street Journal report describing how China's Zhipu AI has repor…
Serenity, the small-cap stock-picker whose reconstructed views this site tracks, spent today threading a single piece of M&A news through his long-running optical-interconnect framework. The trigger: a report that Elon Musk's SpaceX (here tagged SPCX, the still-private rocket and satellite company whose anticipated mega-IPO Serenity has flagged as a defining liquidity event) has acquired Mesh, an …
Serenity, the stock-picker tracked on this site for his focus on the obscure upstream suppliers feeding the AI buildout, spent Friday balancing one piece of bullish thematic news against a broad, ugly day for global equities. Power semiconductors: pricing as demand validation. His most constructive note centered on a wave of price increases sweeping Chinese power-chip makers. He pointed to Yangji…
Serenity, the stock-picker who back-maps the AI supply chain to find obscure upstream "chokepoints" — critical suppliers with few substitutes — spent Wednesday in a reflective, self-critical mood, acknowledging a sharp drawdown and laying out a revised framework for when markets actually pay him for being early. Owning the losses. He jokingly rebranded his recent results "Diversified Losses," sin…
Serenity, the small-cap investor who back-maps the AI buildout to find obscure upstream suppliers, spent today on the demand side of his framework — the hyperscalers whose spending he treats as a telegraph for where his bottleneck bets pay off. He also flagged an amusing meme-stock episode tied to one of his core holdings. A Reddit-fueled rally in Wendy's Serenity noted with some amusement that …
Serenity, the stock-picker whose reconstructed views this site tracks, spent the day hammering his central conviction: that the obscure suppliers feeding the AI optical buildout are where the real money sits, not the crowded mega-caps. The CW laser chokepoint thesis, restated. His framework treats Nvidia's (NVDA) roadmap as a demand signal and hunts the smallest upstream bottleneck. Today he lean…
Serenity, the stock-picker who hunts the small upstream suppliers feeding the AI buildout, spent Saturday mostly on a single new name — a Korean optical company — while reaffirming where his real conviction lies. Supply chains as a trade weapon He opened by arguing that the real leverage in trade negotiations sits in frontier supply chains, not consumer-goods exports, pointing to chokepoints — c…
Serenity, the stock-picker tracked here for his bet on the obscure upstream suppliers feeding the AI buildout, spent Saturday airing what he called unfinished research: a hunt for holding companies that trade well below the value of the businesses they own. The NAV-discount hunt. A NAV discount is when a parent trades for less than its stake in a listed subsidiary is worth — a setup he likes when…
Serenity spent Friday taking unusually candid stock of his own portfolio, walking through what has worked, what has hurt, and where he thinks he simply missed. A rare honest scorecard. He reiterated that his book rests on three pillars — neoclouds/AI power, the memory supercycle, and AI photonics — and argued he landed on the standout in each: Nebius (NBIS), his favored AI cloud and "next hypersc…
Serenity, the small-cap-focused stock-picker who back-maps the AI buildout to its most obscure upstream suppliers, had a busy day spanning valuation arbitrage, a fresh catalyst in one of his European holdings, and a recap of his two dominant themes. The NAV-discount hunt. He opened by siding with activist Palliser Capital on Taiwan-listed WUS Printed Circuit (2316), a PCB maker he owns. His gripe…
A busy day for Serenity, the stock-picker who builds his portfolio by back-mapping the AI buildout to its smallest upstream suppliers. The recurring idea is the "chokepoint" — a critical part of the supply chain with few substitutes that the whole AI rollout depends on, particularly the light sources for co-packaged optics (CPO), where the optical engine sits beside the switch or GPU chip. The CW…
A busy session for Serenity, the stock-picker who hunts the small upstream suppliers feeding the AI buildout, as fresh reporting appeared to back several of his longest-held theses at once. The laser chokepoint moves into focus. Serenity flagged industry reports that AMD — the accelerator and CPU maker pushing into co-packaged optics (placing the optical engine next to the chip to save power) via…
