Our read on each fund

ETF.net Research

AIBUCDirexion Daily AI and Big Data Bull 2X ETF

ROMAProShares Ultra Technology

In short

AIBU The leveraged AI trade spread across a basket instead of one chip name: AIBU targets 200% of the daily move of a roughly 40-stock US AI and big-data index, resetting every trading day.

ROM The original 2x tech trade. Since 2007, ROM has aimed at twice the daily move of the S&P 500's technology sector: a double dose in a category now stacked with triples.

Stated mandate

AIBU The Fund seeks 200% of the Solactive US AI & Big Data Index’s daily performance before fees and expenses, resetting its target each trading day. It is not designed to deliver 200% of the index over periods other than one trading day.

ROM ROM seeks daily investment results, before fees and expenses, corresponding to twice the daily performance of the S&P Technology Select Sector SM Index.

Why people hold it

  • AIBU Written-down mandate: 200% of the daily move of the Solactive US AI & Big Data Index, before fees, reset each trading day. The index picks the AI names, not a manager.sec.gov
  • 0.96% net of a waiver through September 1, 2027 (1.05% gross), near the category's typical fee and close to QLD at 0.89% net of a waiver through September 30, 2027.
  • The dial is set at 2X, not 3X: each day's index move is doubled, spread across roughly 40 US AI and big-data stocks rather than one.direxion.com
  • Holds up in the upper half of a crowded leveraged-bull peer group.
  • ROM Two times, not three. A 2x daily target means smaller swings and less compounding drag than a 3x fund chasing the same sector.sec.gov
  • Live since January 2007, so it has run through the 2008 crash and the full tech cycle since. Long mileage is rare in geared funds.
  • 0.93% a year, flat, with no waiver propping it up. Peer QLD runs 0.89%, but only net of a waiver through September 30, 2027.
  • One of the strongest implementations in the leveraged-bull pack, from an issuer that has run geared funds since the category's early days.proshares.com

Worth knowing

  • AIBU The 200% target is a one-day target. Over longer holds, compounding takes over and results can differ from 200% of the index, more so when the index swings.sec.gov
  • A small, lightly traded fund, so bid-ask spreads can run wider than in the category's heavyweights.
  • Launched in 2024, so there is a shorter stretch of market conditions behind it than longer-running leveraged funds.
  • ROM The 2x target resets at each close, so results over weeks or months depend on the path the sector takes, not just where it ends up.sec.govproshares.com
  • Trades thinner than the category's headline names, so spreads and limit orders matter, especially in size.
  • About 80 tech names from the S&P 500. That is one concentrated sector bet, doubled, in both directions.
