JPMorgan analyst Michael Weinstein raised his price target for Johnson & Johnson shares to $148 from $140 ahead of the European Society of Cardiology beginning on August 26. The big event for J&J is the presentation of the COMPASS trial, investigating the use of Xarelto for the treatment of coronary or peripheral artery disease, Weinstein tells investors in a research note. His statistical analysis suggests a minimum 25% reduction in major adverse cardiac events, or MACE. This would make COMPASS a "landmark event in the treatment of CAD/PAD" and lead to Xarelto being adopted as the new standard of care in this greater than $5B indication, Weinstein writes. He recommends buying J&J shares ahead of the European Society of Cardiology meeting and keeps an Overweight rating on the name.
