In an equal-weighted portfolio or index, the same amount is invested in all securities each period. A daily equal-weighted portfolio is reweighted each day, while a monthly equal-weighted portfolio is reweighted each month. Therefore compounded daily index returns over a month are not equivalent to monthly index returns for an equal-weighted portfolio. An equal-weighted portfolio incurs large transaction costs in practice, especially if maintained daily, since shares must be bought and sold each period as prices change to maintain weighting.

Ordinary distributions are distributions made to shareholders of a security from company profits. These represent income to the shareholder and are not included in the capital appreciation of the security. CRSP returns calculations use the distribution codes to determine whether a distribution is ordinary or non-ordinary. A distribution is considered ordinary if any of the following conditions are true:
- First digit of the Distribution Code is 1 (1***, where *=anything)
- First digit of the Distribution Code is 2, third digit is anything but 3, and fourth digit is 2 or 8 (2*‡2, 2*‡8 where *=anything and ‡=anything except 3)
- Any Distribution Code with a Factor to Adjust Price of either 0 or -1
- First digit of the Distribution Code is 6 and the fourth digit is 2 or 8 (6**2, 6**8 where *=anything)
