A call is right when the stock rose after an in call or fell after an out call. Trend plays are built to take many small losses for a few big wins, so their hit rates run lower; being right often isn't the same as making the most money. How we test a play.

Next earnings report

Wed Oct 28, 2026 before the open

From Yahoo Finance's calendar; dates can move. Analysts expect earnings per share of 0.75.

Over its last 12 reports, BSX's typical move against the S&P 500 at the first close after the report was ±3.0% (median size, either way); it finished ahead of the index 11 times.
BSX after beats of 5% or more: ahead of its index at the first close after the report 17 of 19 times (median +2.4%).
BSX after misses of any size: behind its index at the first close after the report 2 of 7 times (median +1.5%).
Across all covered stocks, beats of 5% or more were followed by a gain against the index 64% of the time and misses by a drop 62% of the time.

Whether a report beats is only known once it is out, so these say how the stock has reacted, not which way it will go.
