None sourced yet. A company is listed only when its own SEC filing or press release commits to this edition; the organiser's abstract list usually lands a few weeks before the meeting.
What presenting companies' shares did, across the whole study
Across 1,425 presentations at major medical meetings from 2017 to 2026, the median presenting company's stock moved −0.03% in the 30 trading days before the meeting (49.8% rose) and −1.59% in the 5 trading days after (39.4% rose). Small caps: +2.75% before (n=298); nano caps: −7.86% (n=108). The middle half of all presenters ranged from −10.41% to +13.58%. The study is anchored on the meeting start date, not on the abstract release; the true catalyst may be earlier. This measures what happened; it is not a forecast for any company. Full study, with the method and its limits.

How ASCO stocks have traded historically

Median share-price move around a presentation, measured across 276 ASCO presentations in our study (2017-2026).

10 days before+0.80%  54% rose · n=276
Presentation day-0.02%  48% rose · n=276
5 days after-0.81%  45% rose · n=276
10 days after-0.98%  42% rose · n=276
By company size (10-day run-up → 5 days after)

Micro ($50-300M)-0.52% into it  →  -2.21% after  n=47

Read the whole row, not just the first line: across this study stocks have drifted up into these meetings and down out of them, and the effect is largest in the smallest companies. Medians are shown because a handful of large moves pulls an average away from the typical case. This is a historical distribution for a cohort of companies, not a forecast for any single company, and not investment advice. Methodology and the full study.

FAQ

When is ASCO 2027?
ASCO Annual Meeting 2027 runs June 4-8, 2027 in Chicago, US. The date comes from the organiser's own announcement; check the organiser's site for the final programme.
Which biotech companies are presenting at ASCO 2027?
None sourced yet. We list a company as presenting only when its own SEC filing or press release commits to this edition -- abstract titles and rumours don't qualify. The conferences page updates as filings land.
How do biotech stocks typically trade around ASCO?
In our study of 276 ASCO presentations (2017-2026), the median stock moved +0.80% over the 10 trading days before the presentation (54% of them rose), -0.02% on the day itself, and -0.81% over the 5 trading days after. The pattern across the whole study is a drift up into these meetings and down out of them, strongest in the smallest companies. That is a historical distribution for a cohort, not a prediction for any one company, and not investment advice.
Why do medical conference dates matter for biotech stocks?
Trial results are often presented first at medical meetings, so a company's announced presentation is a dated, public catalyst. We publish a study of how biotech stocks have historically traded into conference presentations on the research page; it is historical measurement, not a prediction, and none of this is investment advice.
