Upturn AI SWOT
ProShares UltraPro Short MidCap400
ETF Overview
Overview
The ProShares UltraPro Short MidCap400 (MRZ) is an inverse leveraged ETF designed to seek daily investment results, before fees and expenses, that are three times the inverse of the daily performance of the S&P MidCap 400 Index. It aims to profit from significant declines in the mid-cap stock market. The ETF utilizes derivatives, such as futures and swaps, to achieve its leveraged inverse exposure.
Reputation and Reliability
ProShares is a well-established issuer of ETFs, particularly known for its suite of leveraged and inverse products. They have a significant presence in the ETF market and are generally considered reliable for offering specialized investment vehicles. However, their leveraged and inverse products carry higher risks and are intended for sophisticated investors.
Management Expertise
ProShares employs experienced professionals in ETF product development, portfolio management, and risk management. The management team has extensive experience in creating and overseeing complex financial instruments, including leveraged and inverse strategies.
Investment Objective
Goal
To provide investors with three times the inverse of the daily performance of the S&P MidCap 400 Index. This means the ETF aims to increase in value when the S&P MidCap 400 Index falls.
Investment Approach and Strategy
Strategy: The ETF does not track an index passively. Instead, it actively uses derivatives to achieve its stated objective of three times the inverse daily return of the S&P MidCap 400 Index. This is a dynamic, short-term strategy, and its performance over longer periods can deviate significantly from three times the inverse of the index's return due to the effects of compounding.
Composition The ETF holds a portfolio of financial instruments, primarily derivatives like futures contracts, swap agreements, and options, designed to replicate the leveraged inverse exposure to the S&P MidCap 400 Index. It does not hold a significant portion of the underlying stocks of the index itself.
Market Position
Market Share: Information on the specific market share of individual leveraged/inverse ETFs is typically not granularly reported in a way that allows for precise calculation. However, ProShares holds a significant position in the leveraged and inverse ETF segment.
Total Net Assets (AUM): The AUM for MRZ fluctuates daily with market conditions and investor flows. As of recent data, the AUM is in the tens of millions of US dollars, reflecting its niche and higher-risk nature.
Competitors
Key Competitors

- ProShares Short MidCap400 (SFY)
Competitive Landscape
The market for leveraged and inverse ETFs is dominated by a few key issuers, with ProShares being a primary player. Competitors offer similar products with varying levels of leverage (e.g., 1x, 2x, 3x) and shorting strategies. MRZ's advantage lies in its 3x inverse exposure, offering amplified potential gains during market downturns. However, its disadvantages are the amplified risks, including significant potential for losses if the market moves against the ETF, and the compounding effects that make it unsuitable for long-term holding.
Financial Performance
Historical Performance: Historical performance data for MRZ is highly volatile and directly tied to the performance of the S&P MidCap 400 Index. Due to its leveraged inverse nature, its performance over periods longer than one day will likely differ substantially from three times the inverse of the index's cumulative return. Significant declines in the S&P MidCap 400 can lead to substantial gains for MRZ, but sustained uptrends in the index can result in rapid and significant losses for the ETF.
Benchmark Comparison: The ETF's benchmark is essentially the daily inverse performance of the S&P MidCap 400 Index, multiplied by three. Its performance is directly measured against this objective, not against a passive index. Over any given day, it aims to achieve this triple inverse return.
Expense Ratio: 0.96
Liquidity
Average Trading Volume
The ETF typically has a moderate average trading volume, indicating that it is generally liquid enough for most active traders to enter and exit positions without significant price impact.
Bid-Ask Spread
The bid-ask spread for MRZ is generally tight, reflecting the liquidity provided by authorized participants and market makers, which helps to minimize transaction costs for investors.
Market Dynamics
Market Environment Factors
MRZ is highly sensitive to overall market sentiment, economic indicators, and the performance of mid-cap U.S. equities. Economic downturns, increased market volatility, or a bearish outlook on the mid-cap sector would positively impact MRZ's performance. Conversely, a stable or rising market, particularly for mid-cap stocks, would lead to losses.
Growth Trajectory
The growth trajectory of MRZ is inherently tied to its inverse strategy and is not one of consistent asset accumulation. Its AUM and trading volume tend to increase during periods of market uncertainty and expected declines in the S&P MidCap 400. Strategy and holdings are dynamically adjusted daily by the issuer to maintain the leveraged inverse exposure.
Moat and Competitive Advantages
Competitive Edge
MRZ's primary competitive edge is its provision of 3x inverse leverage on the S&P MidCap 400 Index, offering amplified profit potential for short-term bearish bets. This specialized exposure is not widely replicated across all ETF providers. Its structure allows sophisticated traders to express strong conviction views on mid-cap market declines with a single instrument, potentially reducing transaction costs compared to constructing a similar position through individual derivatives.
Risk Analysis
Volatility
MRZ exhibits extremely high volatility due to its 3x leveraged inverse strategy. Its daily price movements can be multiples of the movements in the underlying index, leading to significant potential for both rapid gains and substantial losses.
Market Risk
The primary market risk is that the S&P MidCap 400 Index rises instead of falls. In such a scenario, MRZ will incur significant losses. Additionally, the compounding effect inherent in leveraged ETFs means that over periods longer than one day, its performance can deviate significantly from the stated multiple of the inverse index performance, leading to unexpected results. There is also the risk of liquidity drying up during extreme market stress.
Investor Profile
Ideal Investor Profile
The ideal investor for MRZ is an experienced, short-term trader or sophisticated institutional investor who has a strong conviction that the S&P MidCap 400 Index will experience a significant decline in the very near future. They must fully understand the risks associated with leveraged and inverse ETFs, including the potential for rapid and total loss of capital.
Market Risk
MRZ is strictly for active traders and very short-term (daily) investment horizons. It is absolutely unsuitable for long-term investors, passive index followers, or anyone seeking steady, compounding returns. Its design is to capitalize on short-term market dislocations.
Summary
The ProShares UltraPro Short MidCap400 (MRZ) is a high-risk, leveraged inverse ETF designed to achieve three times the inverse of the daily performance of the S&P MidCap 400 Index. It utilizes derivatives to achieve its objective and is intended for sophisticated traders with a short-term bearish outlook on mid-cap U.S. equities. Due to its leveraged nature and compounding effects, it is unsuitable for long-term investment and carries a high risk of significant losses if market expectations are not met.
