Which index weighting methodology structurally captures a contrarian rebalancing premium by systematically selling recent winners and buying recent losers?

• A.Equal-weighting methodology
• B.Market-capitalization weighting
• C.Momentum-based weighting
• D.Fundamental macroeconomic weighting

What behavioral phenomenon is a 52-week low strategy primarily attempting to exploit when naive investors aggressively sell off distressed assets on negative news?

• A.Mean reversion, where prices temporarily driven down by panic are expected to bounce back to their intrinsic historical averages.
• B.The gambler's fallacy, which assumes that a stock that has lost value for 52 weeks is mathematically guaranteed to go up.
• C.Trend following, which assumes the negative news will generate sustained downward momentum that can be shorted.
• D.Tax-loss harvesting, where investors sell off losing assets to offset capital gains elsewhere in their portfolio.

Between January 2022 and June 2026, how did the cap-weighted SPY perform relative to the equal-weighted RSP due to mega-cap concentration?

• A.SPY significantly outperformed RSP because the massive gains of a few mega-cap tech stocks heavily influenced the cap-weighted index.
• B.RSP outperformed SPY because equal weighting allowed investors to capture the higher growth potential of the smaller companies in the index.
• C.SPY and RSP performed nearly identically because both funds are composed of the exact same 500 companies.
• D.SPY outperformed RSP primarily because it has a lower expense ratio and significantly higher daily trading volume.

Under the 52-Week High Momentum Effect (George & Hwang 2004), why does proximity to the 52-week high historically possess stronger predictive power for future returns than the 52-week low?

• A.Proximity to the 52-week high signals that the stock is overvalued and due for an immediate mean reversion, whereas the 52-week low indicates a value stock primed for a rebound.
• B.The 52-week high triggers automatic institutional buy algorithms that mechanically push the price higher, whereas the 52-week low lacks such automated support.
• C.Investors use the highly visible 52-week high as a psychological anchor, causing them to underreact to positive news and creating a delayed upward price adjustment.
• D.Stocks near their 52-week high typically exhibit higher trading volumes, which reduces bid-ask spreads and lowers transaction costs for momentum traders.

According to the Overreaction Hypothesis (De Bondt & Thaler 1985), what specific behavioral mechanism creates the temporary mispricings that allow beaten-down stocks to outperform over subsequent horizons?

• A.Institutional investors deliberately short-sell distressed companies to drive them into bankruptcy before covering their positions.
• B.Investors slowly incorporate new negative earnings information into prices, creating a gradual downward drift.
• C.Investors overweight recent negative news and excessively extrapolate poor past performance into the future.
• D.High transaction costs and illiquidity prevent rational arbitrageurs from immediately buying undervalued assets.

How does the Anchoring and Adjustment Heuristic (Tversky & Kahneman 1974) explain the systematic investor underreaction to fundamental news for stocks currently trading near their 52-week lows?

• A.Investors assume the stock is "on sale" and will naturally revert to its historical average, leading them to buy without fully analyzing the new fundamental data.
• B.Investors extrapolate the recent downward price trend into the future, causing them to dismiss the new fundamental news entirely.
• C.Investors fixate on the stock's recent depressed price level and fail to sufficiently update their valuation upward when positive fundamental news is released.
• D.Investors feel the emotional pain of the stock's recent decline more intensely than the potential gain from the positive news, causing them to avoid trading.

If current AI-driven capital expenditures disproportionately benefit mega-cap technology firms, how would this environment most likely impact the 12-month relative performance of an equal-weighted 52-week low strategy?

• A.The strategy will likely outperform because historical mean-reversion principles dictate that capital-intensive growth cycles eventually rotate into beaten-down value stocks.
• B.The strategy will likely underperform a broad market-cap weighted index because it systematically excludes the high-performing mega-cap tech firms that are capturing the AI capital expenditure benefits.
• C.The strategy will generate superior risk-adjusted returns because AI innovations automatically reduce operational costs for all struggling companies, guaranteeing a broad market recovery.
• D.The strategy's relative performance will remain unaffected because corporate capital expenditures are capitalized on the balance sheet rather than immediately expensed on the income statement.

How would aggressive antitrust scrutiny and regulatory breakups targeting mega-cap technology companies alter the expected risk-adjusted return profile of cap-weighted indices compared to equal-weighted indices?

• A.It would decrease the risk-adjusted returns of equal-weighted indices because breaking up mega-caps destroys overall market value, dragging down smaller companies that rely on them.
• B.It would improve the risk-adjusted returns of cap-weighted indices because the newly spun-off companies from the breakups would immediately command higher combined market capitalizations.
• C.It would likely improve the relative risk-adjusted returns of equal-weighted indices, as they have lower concentration risk in the targeted mega-caps and higher exposure to smaller competitors.
• D.It would cause both indices to experience identical declines in risk-adjusted returns because technology companies rely on global supply chains that are disrupted by regulatory actions.

How do the return predictions of the Overreaction Hypothesis (De Bondt & Thaler 1985) conflict with the 52-Week High Momentum Effect (George & Hwang 2004) when evaluating stocks at 52-week lows?

• A.The Overreaction Hypothesis predicts continued underperformance due to panic selling, while the 52-Week High effect predicts a rebound as investors anchor to the past high.
• B.Both theories predict that stocks at 52-week lows will experience a strong rebound, but they disagree on whether the recovery takes three months or three years.
• C.The Overreaction Hypothesis predicts a rebound due to mean reversion from excessive pessimism, whereas the 52-Week High effect predicts continued underperformance due to anchoring.
• D.The Overreaction Hypothesis predicts an increase in implied volatility for stocks at 52-week lows, whereas the 52-Week High effect predicts a decrease in trading volume.
