Side by side
As of Oct 28, 2026. Source: ETFIQ.
BAPR is already at its cap, so more rise in the index adds nothing to it before the period ends.
They do not reset together. BAPR has 154 days of its period left and BSEP has 307, so the two are not the same bet on the same months.
Both are Innovator funds, so the difference between them is the terms rather than the house.
Where each one stands today
BAPR resets first, on Mar 31, 2027, 154 days from now; BSEP runs to Aug 31, 2027, 307 days. BAPR can still gain 5.0% before its cap, BSEP 18.7%. A fall from here reaches BAPR’s buffer after 11.4% and BSEP’s after 0.9%. Both track SPY, so what separates them is where each is in its own period.
BAPR and BSEP are built for the same job. How do they differ in cost, holdings and results?
- Protection and cap. BAPR: Absorbs the first 9% of loss on SPY and caps the gain at 18.5%, over a period ending Mar 31, 2027. BSEP: Absorbs the first 9% of loss on SPY and caps the gain at 19.8%, over a period ending Aug 31, 2027. The starting caps are 1.3 points apart.
- Outcome period. BAPR runs Mar 31, 2026 to Mar 31, 2027 with 154 days left; BSEP runs Aug 31, 2026 to Aug 31, 2027 with 307 days left.
- One-year total return. Over 1 year to Oct 28, 2026 BAPR returned +16.2% and BSEP +11.3% with distributions reinvested, a gap of 4.9 points.

BAPR
SPY had already risen past this fund's cap of +18.5% for the period on Oct 28, 2026, so in index terms there is no more upside to collect. The fund's own price can still drift up to about 5.0% as the period runs out. The fund's price can fall 11.4% from here before the buffer starts absorbing losses, by the issuer's number. In index terms, SPY can fall 15.7% from today's level to the point where the buffer begins. Protection left, in index points: 9.0% of the 9.0% buffer still sits below today's SPY level. 154 days remained on Oct 28, 2026. On Mar 31, 2027 the period ends and a new cap is set.
BSEP
From its price on Oct 28, 2026, the fund can gain about 18.7% more before it reaches its cap. The fund's price can fall 0.9% from here before the buffer starts absorbing losses, by the issuer's number. In index terms, SPY can fall 0.6% from today's level to the point where the buffer begins. 307 days remained on Oct 28, 2026. On Aug 31, 2027 the period ends and a new cap is set.

How this is computed
It is a place in a set, not a rating or a recommendation.
ETFIQ calculates every number from each issuer’s published outcome-period terms. Buffer ETFs hold options on an index, not shares, so there is no holdings overlap to report.
Every number is an ETFIQ calculation with distributions reinvested.
