This is an inverse ETF that tracks -1x the daily performance of the Russell 2000 Index. It is structured to rise by the corresponding amount when the index falls over a single day, and it is used as a tool to respond to short-term downturns in the small-cap market.

It suits experienced investors who expect a short-term decline in the US small-cap market or want to hedge existing long positions.

It is a passively managed (index-tracking) ETF operated by ProShares.

It uses derivatives such as swaps to track the daily return of the Russell 2000 Index at -1x, in the opposite direction. Because exposure is reset every day, the fund targets single-day performance, and cumulative returns over multiple days can differ from the simple opposite of the index.

• Provides inverse exposure to a small-cap index
• A short-term tool built on a daily reset

Assets under management (AUM) are $169.1M, and the Expense Ratio is 0.95% per year.

Compared with SH and PSQ, which belong to the same ProShares inverse family, its distinguishing feature is that it tracks a small-cap index.

It has moved in the opposite direction of the Russell 2000, falling when the index rises and rising when the index falls. Small caps are highly sensitive to the economic cycle and prone to volatility, so the inverse exposure also tends to swing widely.

Money tends to flow in for short-term hedging when concerns about a market correction grow, while inflows tend to slow in rising markets. Because it is primarily a short-term tool, it tends to see faster turnover than capital held for the long term.

Its strength is that it serves as a hedge against small-cap declines, while its weakness is the risk of losses from long-term holding due to the daily reset.

SH, PSQ, and SPXU shown in the table belong to the same ProShares inverse family, but they track different indexes and use different multiples. To respond to large-cap declines, you could consider SH, the S&P 500 inverse, or PSQ, the Nasdaq 100 inverse. If you want a larger multiple, SQQQ, which is -3x the Nasdaq 100, is an option, and SOXS is an alternative for focusing on declines in the semiconductor sector. If your goal is long exposure to small caps, you should look at a regular Russell 2000 ETF rather than an inverse one.

These are points to review before investing in RWM. Inverse products differ in nature from regular index ETFs, so it is important to check in advance the holding period, the market direction, and the compounding effect of the daily reset.

Because of the daily reset structure, long-term holding can produce results that differ significantly from the simple opposite of the index's performance, and losses accumulate if the market rises contrary to expectations. The higher the volatility, the greater the risk of compounding erosion.

If your goal is to respond to a short-term decline in the US small-cap market or to hedge, this is a tool worth considering. However, it is not suitable for long-term holding, so it is advisable to manage the holding period and market direction carefully.
