Our read on ARB

ETF.net Research

BMerger arbitrage by rulebook. ARB tracks an index of already-announced deals (mergers, takeovers, tender offers, leveraged buyouts) around the world, with foreign currency exposure hedged back to the dollar.

Stated mandate

The Fund seeks to track the performance of the Water Island Merger Arbitrage USD Hedged Index, which reflects a global merger-arbitrage strategy involving announced mergers, takeovers, tender offers, and leveraged buyouts.

Why people hold it

  1. 01The strategy is written into the index, not left to a manager's gut: announced mergers, takeovers, tender offers and LBOs, global in scope.
  2. 02Currency hedged by design. The index is the USD-hedged version, so results lean on deals closing rather than on moves in the euro or the pound.
  3. 03Spread across roughly 90 positions, so a single busted deal lands as a dent rather than a crater.
  4. 04At 0.76%, the fee sits at the midpoint of the merger-arb ETF field and well under First Trust's NTRL (0.95%) and sibling EVNT (1.33%).

Worth knowing

  1. 01Thinly traded. Bid-ask spreads can run wider than on a mainstream index fund, which matters most on large or hurried orders.
  2. 02Deal risk is the whole game: regulators blocking a takeover or a buyer walking away is what hurts here, and the opportunity set shrinks when the deal calendar goes quiet.
  3. 030.76% is specialist pricing, several times what a plain stock index fund costs. You are paying for the arbitrage machinery, not for market exposure.
