For Sociedad Quimica y Minera (SQM), Polymer initiated the position with 19,555 shares valued at about $1.345 million. The article adds that institutional/hedge-fund ownership is 12.41% and cites analyst action: Scotiabank raised its price objective from $100 to $105 and kept a “sector outperform” rating.
In MINISO Group coverage, the article reports insider buying: CEO Guofu Ye purchased 1,950,000 shares on May 29 at an average cost of $3.28 per share (total value $6,396,000).
For MP Materials, Polymer’s new stake came via a 13F filing: 10,000 shares worth about $505,000.

For Corning, analyst reactions are spelled out as both downgrades and higher targets: Wall Street Zen downgraded Corning from “buy” to “hold” (June 6), Susquehanna lifted its target from $125 to $180 and rated it “positive” (April 29), and Mizuho raised its target from $190 to $220 with an “outperform” rating (May 12).

Polymer Capital Management HK LTD has sharply boosted its bet on Chinese e-commerce, raising its stake in Vipshop Holdings by 59.4% to 932,407 shares worth $16.49 million, according to HedgeFollow. The move lifts Vipshop to the firm's 10th largest holding, representing 2.3% of a portfolio valued at $1.16 billion across 154 positions.
The Vipshop buy is part of a broader reallocation. Polymer also opened fresh positions in lithium producer SQM, rare-earth miner MP Materials, and Corning Incorporated, while trimming its stake in MINISO Group. The moves signal a pivot toward Chinese consumer recovery, critical minerals, and AI-linked optics.
Polymer's Vipshop buy landed just days before UBS upgraded the stock to "Buy" with an $18.50 price target on June 5, according to Insider Monkey. Vipshop had already shown momentum — the company reported Q1 2026 revenue of $3.85 billion on May 21, beating expectations, per PR Newswire.
Not everyone is convinced. Benchmark analyst Fawne Jiang kept a cautious "Hold" rating, citing "limited visibility into discretionary spending recovery," according to Investing.com. Institutional investors collectively own 48.82% of Vipshop's shares, suggesting the stock remains a contested bet among professional money managers.
Even as Polymer trimmed its MINISO position, CEO Guofu Ye moved in the opposite direction. He purchased 1.95 million shares on May 29 at an average price of $3.28 per share — a total outlay of $6.396 million — according to Stock Titan. Ye said the buy reflects his "unwavering confidence in MINISO's long-term value."
Insider purchases of that size often signal that management believes the stock is undervalued. The move may help stabilize MINISO's share price after institutional selling put downward pressure on it.
Polymer initiated a 19,555-share position in Sociedad Quimica y Minera (SQM), valued at roughly $1.345 million. Scotiabank analyst Ben Isaacson supports the thesis, raising his price target on SQM from $100 to $105 and keeping a "Sector Outperform" rating on May 28, according to Seeking Alpha. Isaacson argues SQM's all-in lithium cost of about $4,500 per metric ton makes it one of the world's lowest-cost producers.
Polymer also picked up 10,000 shares of MP Materials, worth around $505,000, per WhaleWisdom. MP Materials carries a beta of 1.86 and a P/E ratio of -137.37, reflecting its high-volatility, pre-profit profile. Its stock has swung between $28.35 and $100.25 over the past year. Institutional investors own 52.55% of the company.
Polymer also opened a new position in Corning, buying 9,222 shares, according to MarketBeat. But the stock is dividing Wall Street. Mizuho raised its target to $220 with an "Outperform" rating on May 12. Susquehanna set a $180 target and rated it "Positive" on April 29. Then on June 6, Wall Street Zen downgraded Corning from "Buy" to "Hold," citing valuation concerns after a 140% six-month rally.
CEO Wendell Weeks added to the uncertainty on June 9 by selling 100,000 shares for $18.6 million — nearly 10% of his direct holdings — per MarketBeat. Corning slid 5.3% in early June as investors weighed the AI-optics run-up against renewed valuation worries, according to Quiver Quantitative. Institutional investors hold about 69.8% of the stock, keeping it firmly in professional hands.
