How SABCS stocks have traded historically

Median share-price move around a presentation, measured across 28 SABCS presentations in our study (2017-2026).
30 days before+5.42%  57% rose · n=28
10 days before+2.23%  54% rose · n=28
Presentation day-2.02%  25% rose · n=28
5 days after-3.33%  36% rose · n=28
10 days after-1.17%  36% rose · n=28
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 SABCS 2026?
San Antonio Breast Cancer Symposium 2026 runs December 8-11, 2026 in San Antonio, 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 SABCS 2026?
From company filings and releases we have sourced 1 presenter commitment for this edition: OLMA. This is not the organiser's programme -- only presentations companies have themselves announced, each linked to its filing on the conferences page.
How do biotech stocks typically trade around SABCS?
In our study of 28 SABCS presentations (2017-2026), the median stock moved +2.23% over the 10 trading days before the presentation (54% of them rose), -2.02% on the day itself, and -3.33% 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.
