• AltShares Merger Arbitrage ETF (NYSE Arca: ARB) is an established merger arbitrage ETF. The ETF seeks to track the Water Island Merger Arbitrage USD Hedged Index, which focuses on publicly announced mergers and acquisitions.
• The ARB ticker can create confusion because Arbitrum (CRYPTO: ARB) uses the same symbol in the cryptocurrency market.
• Separately, Standard Chartered (LSE: STAN) has issued a bullish long-term target for Arbitrum, but that forecast applies to the crypto token, not the ETF.

AltShares Merger Arbitrage ETF (NYSE Arca: ARB) is an exchange-traded fund focused on a specialized merger arbitrage strategy. The fund seeks investment results that correspond, before fees and expenses, to the performance of the Water Island Merger Arbitrage USD Hedged Index, according to AltShares’ fund documents. The strategy is designed to invest in definitive, publicly announced merger and acquisition transactions. 

Merger arbitrage typically involves buying shares of a target company after an acquisition is announced and attempting to capture the spread between the market price and the agreed deal price. In stock-for-stock transactions, the strategy may also use short exposure to the acquiring company to hedge deal-value risk. The fund’s summary prospectus lists NYSE Arca, Inc. Symbol: ARB and describes the fund’s merger arbitrage approach in detail. 

Water Island Capital launched the AltShares Merger Arbitrage ETF in 2020, while 2026 filings describe a planned reorganization of AltShares Trust funds into substantially identical funds under The Arbitrage Funds. That means the recent development is better described as a fund reorganization, not the creation of a brand-new investment strategy.

The ARB ticker may still confuse investors because Arbitrum (CRYPTO: ARB) uses the same symbol in digital asset markets. Arbitrum is unrelated to the AltShares ETF. It is a cryptocurrency and blockchain ecosystem token, while AltShares Merger Arbitrage ETF is a regulated exchange-traded fund.

Separately, 24/7 Wall St. reported that Standard Chartered’s Geoff Kendrick set a $10.00 long-term price target for Arbitrum by 2030 and described the token as “hugely undervalued.” That forecast applies only to Arbitrum (CRYPTO: ARB), not to AltShares Merger Arbitrage ETF (NYSE Arca: ARB). Investors should avoid mixing the ETF’s merger arbitrage strategy with crypto price targets or blockchain-related analysis. 24/7 Wall St.
