• No single stock can have more than 33% weight in the index.
• The sum of the weights of the top 3 stocks in the portfolio cannot exceed 63% on average.
• Stocks that climb above these ceilings distribute the excess weight equally over the remaining stocks in the index, thereby diluting that stock's contribution.
