What metric measures the percentage of available shares in the lending market that are currently borrowed by short sellers?

Learn more about this

• A.The ratio of total short interest to the total outstanding public float of the stock.
• B.The percentage of total daily trading volume that consists of short sales.
• C.The percentage of a security's available lendable supply that is currently on loan to short sellers.

According to the SEC, what was the primary reason for 62% of share recalls during the fourth quarter of 2020?

Learn more about this

• A.Retail investors demanding physical delivery of their stock certificates to trigger a short squeeze.
• B.Lenders recalling shares primarily to exercise their proxy voting rights ahead of corporate actions or annual meetings.
• C.Brokers recalling shares because the short seller failed to maintain adequate margin requirements.
• D.The SEC mandating recalls to audit the total number of synthetic shares in circulation.

During the peak of the GameStop squeeze, buy-to-cover orders accounted for what maximum percentage of total buy volume?

Learn more about this

• A.Buy-to-cover volume accounted for over 100% of the float as short sellers bought back synthetic shares multiple times.
• B.Buy-to-cover volume made up the vast majority of institutional trading, while retail dominated the options market.
• C.Buy-to-cover volume peaked at 50% specifically during the after-hours trading sessions when margin calls were processed.
• D.Buy-to-cover volume was a small fraction, rarely exceeding 10% of total buy volume, indicating the squeeze was driven mostly by retail buying.

Under Limits to Arbitrage, why might rational arbitrageurs be forced to liquidate positions at a loss before prices revert to fundamentals?

• A.Arbitrageurs manage other people's money and face performance-based capital withdrawals if the mispricing worsens in the short term.
• B.Arbitrageurs are perfectly rational but lack the mathematical models to calculate the true fundamental value of the asset.
• C.Arbitrageurs are forced to liquidate because market makers illegally collude to widen bid-ask spreads against them.
• D.Arbitrageurs must liquidate because SEC regulations prohibit holding contrarian positions for more than one fiscal quarter.

According to Brunnermeier and Pedersen's spiral model, what specific funding constraint forces arbitrageurs to deleverage when market volatility increases?

Learn more about this

• A.A decrease in interest rates causes arbitrageurs to over-leverage, leading to a sudden collapse when central banks tighten policy.
• B.Short sellers deliberately naked short the stock to drive the price to zero, which permanently destroys the company's funding liquidity.
• C.An increase in asset volatility causes brokers to raise margin requirements and haircuts, forcing arbitrageurs to sell assets and further depressing prices.
• D.Retail investors coordinating on social media drain the market's liquidity by refusing to sell their shares.

In Dynamic Delta Hedging, what market friction or condition causes the continuous hedging assumption to break down during a gamma squeeze?

Learn more about this

• A.The continuous hedging assumption fails because the SEC halts trading on all options during a gamma squeeze.
• B.The assumption of continuous trading breaks down when prices gap or jump discretely, preventing market makers from adjusting their hedges in real time.
• C.The model assumes market makers will always take a directional bet on the underlying stock rather than remaining delta-neutral.
• D.Market makers intentionally stop hedging to manipulate the options market and steal premiums from retail investors.

How would the SEC's transition to T+1 settlement specifically alter the funding constraints described in Brunnermeier and Pedersen's liquidity spiral model?

Learn more about this

• A.It reduces the time capital is locked in the clearinghouse, thereby lowering margin requirements and easing funding liquidity constraints for market participants.
• B.It increases funding constraints by forcing arbitrageurs to post collateral twice as fast during periods of high volatility.
• C.It completely eliminates the possibility of short squeezes because naked short selling is mathematically impossible under a T+1 regime.
• D.It shifts the funding burden entirely from institutional arbitrageurs to retail brokers, who must now pre-fund all client orders.

If AI sentiment detection perfectly predicts retail coordination, how does this impact the core systematic risk assumption in the Noise Trader Risk model?

Learn more about this

• A.It amplifies noise trader risk because arbitrageurs will blindly follow the AI, turning themselves into noise traders.
• B.It proves that retail investors are always rational, thereby invalidating the entire concept of noise traders.
• C.It forces the SEC to classify social media sentiment as insider trading, thus legally preventing arbitrageurs from using the data.
• D.By making noise trader behavior predictable, it theoretically eliminates the specific systematic risk that keeps rational arbitrageurs from aggressively betting against them.

How does the primary driver of price distortion differ between Noise Trader Risk and Dynamic Delta Hedging during a retail-driven short squeeze?

Learn more about this

• A.Noise Trader Risk relies on market makers widening spreads, while Dynamic Delta Hedging relies on retail investors buying out-of-the-money put options.
• B.Noise Trader Risk is a legal strategy used by hedge funds, while Dynamic Delta Hedging is an illegal market manipulation tactic.
• C.Noise Trader Risk is driven by unpredictable, irrational retail demand, whereas Dynamic Delta Hedging is driven by the mechanical, deterministic buying of market makers managing risk.
• D.Noise Trader Risk only applies to small-cap stocks, whereas Dynamic Delta Hedging is exclusively observed in large-cap index funds.

While both models address arbitrageur constraints, how do Limits to Arbitrage and Funding Liquidity Spirals fundamentally differ regarding the role of agency capital versus margin volatility?

Learn more about this

• A.Both models prove that retail investors can permanently destroy hedge funds by holding shares in direct registration systems (DRS).
• B.Limits to Arbitrage emphasizes end-investors withdrawing capital due to short-term underperformance, while Funding Liquidity Spirals focus on prime brokers increasing haircuts due to asset volatility.
• C.Limits to Arbitrage focuses on brokers increasing haircuts, while Funding Liquidity Spirals emphasize end-investors withdrawing capital.
• D.Limits to Arbitrage requires arbitrageurs to use only their own personal wealth, whereas Funding Liquidity Spirals assume they only use borrowed money.
