Q1. The abstract of Paul Zarowin’s paper ” Size, Seasonality, and Stock Market Overreaction” was published in Volume 25, No. 1, March 1990 issue of the Journal of Financial and Quantitative Analysis is given below.

Abstract

Recent research finds that the prior period’s worst stock return performers (losers) outperform the prior period’s best return performers (winners) in the subsequent period. This potential violation of the efficient markets hypothesis is labeled the “overreaction” phenomenon. This paper shows that the tendency for losers to outperform winners is not due to investor overreaction but to the tendency for losers to be smaller-sized firms than winners. When losers are compared to winners of equal size, there is little evidence of any return discrepancy, and in periods when winners are smaller than losers, winners outperform losers.

Why is this a violation of market efficiency?

• Overreaction and market efficiency cannot exist together
• This is a violation of market efficiency because you are able to predict the stock price
• Worst stocks can never outperform the best stocks

Q2. The abstract of Paul Zarowin’s paper ” Size, Seasonality, and Stock Market Overreaction” was published in Volume 25, No. 1, March 1990 issue of the Journal of Financial and Quantitative Analysis is given below.

When losers are compared to winners of equal size, there is little evidence of any return discrepancy, and in periods when winners are smaller than losers, winners outperform losers.

Based on this paper abstract, a trading strategy that can earn profits is

• If the loser is smaller compared to winner then short the loser and long the winner
• If the loser is smaller compared to winner then long the loser and short the winner

Based on this paper abstract, a trading strategy that can earn profits is

• If the loser is same size as winner then short the winner and long the loser
• If the loser is same size as winner then long the winner and short the loser

Q5. Gerben Driespronga, Ben Jacobsenb, and Benjamin Maatc published the paper titled “Striking oil: Another puzzle?” in issue 2, Volume 89 of Journal of Financial Economics. The abstract of the paper is given below:

Changes in oil prices predict stock market returns worldwide. We find significant predictability in both developed and emerging markets. These results cannot be explained by time-varying risk premia as oil price changes also significantly predict negative excess returns. Investors seem to underreact to information in the price of oil. A rise in oil prices drastically lowers future stock returns. Consistent with the hypothesis of a delayed reaction by investors, the relation between monthly stock returns and lagged monthly oil price changes strengthens once we introduce lags of several trading days between monthly stock returns and lagged monthly oil price changes.

Based on the information given in the abstract, if the price of the oil decreases this month, what will happen to the stock market return next month?

• The stock market return increases
• The stock market return decreases

Q6. Gerben Driespronga, Ben Jacobsenb, and Benjamin Maatc published the paper titled “Striking oil: Another puzzle?” in issue 2, Volume 89 of Journal of Financial Economics. The abstract of the paper is given below:

• Long the market index
• Short the market index
