3. PORTFOLIO CONSTRUCTION. Assume we go long the top quintile and short the bottom quintile. Given $2 Million of gross exposure (long and short), use signal weighting to compute the positions each week. Bonus: Note that this simple portfolio construction is not perfectly hedged. What might you suggest to improve that?

4. TRADE EXECUTION. What transaction costs should we assume?

5. BACKTEST. Finally, calculate the weekly returns of this strategy. Sum these to get

   the total return of the strategy.
