Answer 1

The false statement is letter "A": We say a portfolio is long those stocks that have negative portfolio weights.

Step-by-step explanation:

The portfolio weight is the portion that a particular asset represents of the overall portfolio. There are many methods helpful to calculate the portfolio weight usually by dividing the dollar value of an asset by the total dollar value of the portfolio. Short positions are taken as negative values inside the portfolio that hold negative weights.
