Amount remaining after all deductions from, or

The weight of your assets is the amount of each
security in your
portfolio relative to the entire portfolio. Weight
changes depending on whether you're selling short or long. With a little
practice, it's easy to tell the difference between
gross weight vs net weight.
Gross Weight
Gross weight is easy to determine. If you have a portfolio that consists of $13,000 long and $3,000 short positions, then you have a total investment of $16,000.
The gross weight of your
long position is 81.25%, and the gross weight of your
short position is 18.75%. In
order to find gross weight, you
need to divide the amount of any given security by the amount of total
securities held. It's up to you whether you
want to use
dollar values or shares as the metric for comparison.
Net Weight
Net weight is slightly more complicated to figure. In our example, we have a portfolio with $3,000 long and $2,000 tied up in short positions. In this case, the net weight of our long positions is +130 and the net weight for our short position is -30. The net weight is based on the total value of your portfolio, and looks at long investments as positive and short investments as negative. The two numbers will always add up to the net of 100.
