June 21, 2025 | New York — Shares of Lyell Immunopharma, Inc. (NASDAQ: LYEL) closed sharply lower on Friday, June 20, dropping 9.29% to end the session at $8.69. The decline marks yet another blow for the clinical-stage biotech firm, which is now down over 79% year-to-date as of June 2025.
The stock’s weak performance has triggered concern among investors heading into the weekend, as the company continues to operate without any commercial-stage products and faces mounting pressure from long-time shareholders.

Why Is Lyell’s Share Price Falling?
There was no single catalyst on Friday that could explain the nearly 10% drop, but the move appears to be rooted in fundamental weakness and continued investor disillusionment.
Lyell, which focuses on developing T-cell therapies for cancer, has been operating in a highly speculative segment of the biotech market. Investors who once bet on the company’s long-term potential are now confronting a lack of meaningful clinical milestones in 2025, alongside ongoing cash burn and dilution fears.
Additionally, recent institutional positioning shows sustained outflows from biotech ETFs that include LYEL, further intensifying the selling pressure. On Friday, trading volume remained above average, suggesting the move was driven in part by institutional rebalancing.
Latest News About LYEL on June 20, 2025
Although Lyell did not issue any formal statements this week, investor sentiment may have been influenced by two key developments:
- An analyst report, reportedly circulated on June 19, downgraded the stock to “Underperform” on the basis of delayed trial readouts and a thinning cash runway.
- Several trading desks noted increased short interest in small- and mid-cap biotech names, especially among firms with no revenue-generating products. LYEL fits squarely in that category.
The combination of muted pipeline news and increasing macro-level caution toward early-stage biotech appears to be weighing heavily on LYEL’s valuation.
Key Stock Metrics as of June 2025
| Metric | Value |
|---|---|
| Current Price | $8.69 |
| Market Capitalization | $128.7 million (approx.) |
| EPS (Trailing 12 Months) | –$1.45 (estimated) |
| Forward EPS (2025E) | –$1.22 (estimated) |
| YTD Performance | –79.50% |
| Shares Outstanding | ~105.2 million |
| Beta | 1.67 |
These figures underscore the risk profile investors are navigating. With a sub-$150 million valuation and negative earnings outlook, Lyell remains among the more speculative biotech names on the market.
Investor Sentiment and Market Outlook for June 2025
Investor sentiment appears to have turned decisively bearish. With LYEL breaking below its previous support near $9.50, the next technical floor may lie around the $8.00 mark, where buyers briefly stepped in earlier this quarter.
Although the stock’s Relative Strength Index (RSI) is now nearing oversold territory, there’s little evidence of a meaningful reversal. For now, market sentiment in June 2025 reflects skepticism rather than opportunism — especially in the absence of tangible clinical progress or partnerships.
Forward-looking commentary remains muted, and with no earnings or trial updates scheduled in the immediate calendar, it’s unclear what might reverse the trend short term.
Conclusion
Lyell Immunopharma ended the trading week on a sour note, down 9.29% Friday and nearly 80% YTD — a dramatic collapse that now places the company in a fragile position as investors reassess their appetite for unproven biotech names. While the company’s early ambitions in reprogramming T-cells for cancer were once a draw, 2025 has so far failed to deliver the pipeline progress needed to support its valuation.
Heading into next week, all eyes remain on whether the company can spark renewed confidence — or whether selling will continue as investors favor biotech firms with clearer near-term pathways to commercialization.
