ProShares Big Data Refiners ETF (DAT) seeks to track the Solactive Big Data Refiners Index, which measures companies that derive significant revenue from collecting, processing, and analyzing large datasets to extract actionable business insights. This thematic technology ETF focuses on the data analytics value chain.
How It Works
DAT uses a passively managed, modified market-capitalization-weighted approach that tracks companies across the big data ecosystem including cloud storage providers, analytics software firms, and data processing specialists. The fund rebalances quarterly to maintain index alignment and typically holds 30-50 companies globally. Holdings are weighted based on their revenue exposure to big data activities rather than pure market cap, creating sector concentration in technology and communication services.
Key Features
- Targets pure-play big data companies rather than broad technology ETFs, focusing on data analytics specialists
- Global exposure includes both established tech giants and emerging data processing companies across developed markets
- Recently launched in 2021, representing one of the newest thematic investing opportunities in data analytics
Risks
- This ETF can lose significant value during technology sector selloffs, potentially declining 40-50% when growth stocks fall out of favor
- Concentrated exposure to big data theme means regulatory changes or privacy concerns could impact multiple holdings simultaneously
- High correlation with broader technology stocks means limited diversification benefits during market-wide tech corrections or rising interest rates
Who Should Own This
Best suited as a satellite holding (5-15% of portfolio) for aggressive growth investors with 3-7 year time horizons seeking targeted exposure to big data trends. High risk tolerance required due to technology sector volatility and thematic concentration. Appropriate for investors bullish on data analytics growth who want pure-play exposure beyond broad tech ETFs.
