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.

No earnings report, rating change, 8-K filing or news story on DXCM was found for this session. Be The Puck's headline archive for DXCM starts Oct 2, so news stories from that day aren't in it.

Next earnings report

Thu Oct 29, 2026 after the close

From Yahoo Finance's calendar; dates can move. Analysts expect earnings per share of 0.67.

Over its last 12 reports, DXCM's typical move against the S&P 500 at the first close after the report was ±9.8% (median size, either way); it finished ahead of the index 6 times.
DXCM after beats of 5% or more: ahead of its index at the first close after the report 22 of 33 times (median +2.7%).
DXCM after misses of any size: behind its index at the first close after the report 7 of 14 times (median −1.1%).
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.
