Index Methodology

Similar to the NASDAQ 100 Index, the Multiples Airlines Index employs a modified market capitalization weighting scheme.

The weight process uses company-level weights, which are derived using company market capitalization.

Company weights are evaluated based on two rules:

Rule 1

No company's weight may exceed 24%.

Rule 2

The aggregate weight of the companies whose weights exceed 4.5% may not exceed 48%.

If neither rule is 'violated', then no adjustments are made. Only in cases where either or both of the rules are 'violated', weight adjustments are made according to a two-stage adjustment process.

Rule 1 adjustment

If no company's initial weight exceeds 24% of the Index, initial weights are used as Rule 1 weights without adjustment. Otherwise, initial weights are adjusted such that no company's weight may exceed 20% of the Index.

Rule 2 adjustment

If the aggregate weight of the companies whose Rule 1 weights exceeds 4.5% and does not exceed 48%, Rule 1 weights are used as the final weights. Otherwise, Rule 1 weights are adjusted such that:

The aggregate weight of the companies whose Rule 1 weights exceeded 4.5% is set to 40%.
Companies with Rule 1 weights below 4.5% may also have their weights adjusted to keep the initial rank order of all companies.

If the two-stage rule process results in a 'violation' of the weighting rules as previously detailed, then the process is repeated until the company weights meet the rule system.
