SCO: Excellent On Its Day, But Timing Is Everything

ProShares UltraShort Bloomberg Crude Oil ETF is designed for short-term, leveraged bearish exposure to oil prices, not for long-term holding. SCO's structure causes significant time decay and tracking error over periods longer than a few days, making it unsuitable for buy-and-hold strategies. SCO is best used for tactical speculation or as a short-term hedge during periods of heightened oil price volatility, such as current Middle East tensions.
