Conviction · Low · more likely to lag the S&P 500 over the next three months
Wrong if: a daily close above $61.86
Note written ·
Price against the kill line
23.4% clear of its kill line on the 13 November 2026 close.
How to read this
This note expects the shares to lag the market, so its kill line sits above the price: a close above the red mark would prove the view wrong. Prices run from low on the left to high on the right. The dot is where the stock closed on 13 November 2026, left of the mark while it is below the line; a dot right of the mark has closed through it.
The scale is stretched near the line, so close calls are easy to see. More than 8% from the line, the stock reads well clear, with a hollow dot to show the figure is off the drawn scale.
The kill line is the research note's own test. The portfolio sells on business facts, not on a price. How the portfolio decides

The thesis
Penguin Solutions' AI-memory growth case is intact on the company's own numbers, but the shares have fallen sharply on financing, inventory and insider-selling worries. The fiscal first-quarter report, expected around 6 January 2027, settles whether Integrated Memory sales and the roughly 40% fiscal 2027 growth outlook hold.
The shares closed at $45.70 on 9 November 2026 in adjusted daily prices. That is 43.9% below the 52-week high of $81.39 and 22.2% lower over three months. The close on 27 October 2026 was $58.99, and the thesis now rests on the next support, the 200-day moving average.
The company moved against the weak price. On 4 November 2026 it affirmed fiscal 2027 net sales guidance of $2.250 billion to $2.596 billion, against a $2.201 billion consensus, and adjusted earnings per share (EPS) of $3.75 to $5.15, against $3.25. On 3 November 2026 a Schedule 13D showed SK hynix holding 9.1% on an as-converted basis.
The story is well known: the 6 October 2026 beat-and-raise is widely known, and attention since the 5 November 2026 selloff has shifted from growth to cash flow and inventory. Operating numbers are unchanged since 6 October 2026. The Cree LED sale, the SK hynix stake and the insider sales are the new facts.
Bullish and bearish views on Penguin Solutions, Inc.
The bull case on Penguin Solutions, Inc. (PENG), in brief: guidance was affirmed after the selloff began. The bear case: the share-price damage is large and fast.
Bull case
- Guidance was affirmed after the selloff began. The 4 November 2026 release kept the fiscal 2027 outlook of $2.250 billion to $2.596 billion in net sales and $3.75 to $5.15 in adjusted EPS. The midpoint of about $2.43 billion implies roughly 40% growth.
- A memory-industry leader became a shareholder. SK hynix's U.S. AI investment arm, through SHIFTIX1 LLC, bought 200,000 convertible preferred shares for about $377.2 million, per its 13D as reported on 3 November 2026. The shares convert at $32.80784 each, below the 9 November 2026 close.
- Memory is the largest segment and still accelerating. Integrated Memory sales were $340.8 million in fiscal Q4, up 158%, and total net sales were $566.7 million, up 68%, per the 6 October 2026 8-K.
- The business mix is moving toward AI. On 4 November 2026 the company agreed to sell its Cree LED business to Transom Capital Group, with terms undisclosed. A Dealroom report describes the unit as flat-growing.
- Analysts remain largely positive. MarketBeat listed a Moderate Buy consensus and an $87.50 average target on 5 November 2026. Goldman Sachs held a Buy with an $85 target and Rosenblatt a Buy with a $100 target.
Bear case
- The share-price damage is large and fast. On 5 November 2026 the shares fell as much as 16.5% mid-day to $40.356 from a $48.35 previous close, per MarketBeat. The 50-day average on that date was $56.11.
- Insiders sold into the decline. Under Rule 10b5-1 plans, Senior Vice President Anthony Frey sold 4,631 shares at $58.91 on 29 October 2026 and Senior Vice President Joseph Clark sold 5,773 shares at $49.66 on 2 November 2026, per SEC Form 4 filings. The amounts are small against 60,241,423 shares outstanding on 14 October 2026.
- Cash flow and the memory cycle draw skepticism. A Seeking Alpha analysis titled "A Sell On Memory Cycle Peak And Cash Flow Uncertainty" flags a $163 million cash burn in fiscal Q4. The fiscal 2026 10-K says purchases from the two largest suppliers rose to $1.3 billion, and warns that excess memory supply has historically pushed prices and margins down.
- One memory customer carries a fifth of sales. The 10-K states that a single Integrated Memory customer accounted for approximately 20% of fiscal 2026 net sales.
- Margins are thinner on AI hardware. Fiscal Q4 non-GAAP gross margin was 28.8%, against 30.9% a year earlier, per the 8-K. Barclays kept an Underweight rating with a $60 target.
Price setup
The shares closed at $45.70 on 9 November 2026, with a 14-day relative strength index (RSI) of 41.3, which is below neutral but not oversold. MarketBeat put the 200-day moving average at $44.32 and the 50-day at $56.11 on 5 November 2026, so the price sits just above the long average and well below the medium one.
The intraday low on 5 November 2026 was $41.54, per MarketBeat. A close under the 200-day average would mark the first time the long trend line gave way in this decline.
Crowding evidence is mixed. Heavy retail attention showed in the 23 October 2026 takeover rumor from an M&A blog, which the company never confirmed, and a 2x daily-reset fund (PENU) amplifies moves in both directions. Two insider sales under pre-arranged plans fell within the past two weeks. The next earnings date is about eight weeks away, so no report sits inside the next 30 days.
Catalysts ahead
- 17 November 2026: Nvidia fiscal third-quarter results. A read on AI server build rates that feed Penguin's Integrated Memory and Advanced Computing sales, and on whether memory-sector sentiment steadies.
- ~17 December 2026 (est.): Micron fiscal first-quarter results. The last direct read on DRAM pricing and AI memory demand before Penguin's own January report.
- ~6 January 2027 (est.): Penguin fiscal first-quarter 2027 results. The first quarter measured against the affirmed outlook; shows whether Integrated Memory sales hold near $340.8 million, whether cash flow and inventory improve, and whether guidance is kept.
What would change the view
A daily close above $61.86, the highest close of the last 20 sessions (15 October 2026), would show the shares leading the S&P 500 and prove this call wrong.
What it trades with
Penguin trades with the memory group: SK Hynix, Micron and SanDisk. SK hynix is also now a 9.1% holder on an as-converted basis, which links the shares to that company's results and to any amendment of its 13D. Nvidia's results set the pace for AI server demand, which feeds the Advanced Computing segment.
SK Telecom previously held the preferred shares, bought for $200 million in December 2024, and the transfer to SK hynix was within the SK Group. The 2x PENU fund adds price-following flow on large days.
