Exercise - Value and momentum
This empirical exercise is based on the work by Assess, Moskowitz and Ped-ersen (2013).
Portfolios and factors construction
Let's construct tradable portfolios from the given dataset.
1. Upload data (filename: Assignment2014.xlsx) in the statistical soft-ware package.
2. Data contain monthly closing prices and price to book ratios for a large cross-section of stocks in the US. The first row contains the ticker of any given stock, whereas the second row contains the sector. Blank cells indicate that no data is available for that particular stock at that particular date.
3. Upload Fama-French and momentum factors monthly data from Ken- neth French's website.
4. Form three momentum portfolios following the methodology of Assess, Moskowitz and Pedersen (2013).
5. Form three value portfolios following the methodology of Assess, Moskowitz and Pedersen (2013).
6. Form the union portfolio (combo portfolio, equation (3) of Assess, Moskowitz and Pedersen, 2013).
7. Form the intersection portfolio as following:
- Select those stocks that feature in the High momentum portfolio and in the Low price to book portfolio (portfolio A).
- Select those stocks that feature in the Low momentum portfolio and in the High price to book portfolio (portfolio B).
Trading strategies
Calculate the return series of the following equally weighted trading strate- gies, rebalanced every month:
- Momentum strategy.
- Value strategy.
- Combo strategy.
- Intersection strategy. The intersection strategy goes long portfolio A and shorts portfolio B.
For any trading strategy, report summary statistics, Sharpe ratios, t-ratios, maximum drawdowns, a plot of the cumulative returns over time, portfolio turnover and the average number of stocks within any portfolio. Comment on the different performances and risk-return profiles of the strategies, on the benefits of combining value and momentum and on the difference between the combo and the intersection strategy.
Risk attribution
Run regressions of each strategy's returns on the three Fama-French factors plus momentum and comment on the sign, size and the significance of the estimated alphas and betas.

Calculate the final velocities of each ball
: Ball 1, with a mass of 150 g and traveling at 15 m/s , collides head on with ball 2, which has a mass of 350 g and is initially at rest. What are the final velocities of each ball if the collision is perfectly elastic

Find with what speed does the ball hit the ground
: With what minimum speed must you toss a 140 g ball straight up to hit the 14 m -high roof of the gymnasium if you release the ball 1.7 m above the ground, With what speed does the ball hit the ground

Does he have a taxable estate
: 1. The only things he owned were a $500,000 life insurance policy and a farm that he bot way back for $1,000,000 but is now worth $5,000,000. The insurance proceeds went directly into a life insurance trust, as the beneficiary. Does he have..

How high does the pendulum reach
: A ballistic pendulum consists of a bullet (Mb=0.1kg) fired at a small wooden block (mw=0.5kg) attached to a string, 25cm long, connected to a pivot. How high does the pendulum reach above it's initial position
