SPBUDAllianzIM Buffer15 Uncapped Allocation ETF

In short

CAUG No data

SPBU Most buffer ETFs cap your upside. SPBU skips the ceiling: its twelve underlying funds take a stated spread off the S&P 500 ETF's return instead, while buffering the first 15% of losses. Laddered monthly, so no single start date defines your year.

Stated mandate

CAUG No data

SPBU The Fund seeks to achieve its objective through a laddered portfolio of twelve AllianzIM U.S. Equity Buffer15 Uncapped ETFs. The underlying strategy seeks to track SPY market-price returns over specified one-year periods while protecting against the first 15% of SPY losses, subject to a stated spread.

Why people hold it

CAUG No data

  • SPBU No upside cap. The underlying Buffer15 Uncapped funds subtract a stated spread from the S&P 500 ETF's one-year return rather than stopping gains at a ceiling.
  • Twelve overlapping one-year outcome periods in one ticket, so the portfolio staggers its resets instead of hanging on a single entry date.
  • The 15% buffer is written into the design: the underlying strategy absorbs the first 15% of S&P 500 ETF losses over each one-year period.
  • At 0.79%, the fee sits right at the median for its buffered S&P 500 peer group, so the uncapped twist costs no premium over standard capped 15% buffers.

Worth knowing

CAUG No data

  • SPBU The spread is what you pay for no cap. Upside arrives as the index return minus that stated spread, so the fund trails plain S&P 500 exposure in strong years.
  • Cost isn't the edge here. Another laddered buffer fund in the same group, BUFF, charges 0.10% at the fund level.
  • Launched in 2025 and thinly traded, so the track record is short and the gap between bid and ask can matter as much as the expense ratio.
