This is a question of your statistical caliber. If the above 50ETF is used as a measure, it will be found that its increase exceeds the broader market. Another example is the deep 100ETF, which has increased by almost five times, but the deep index is only about four times. In theory, the increase of an index ETF will exceed the increase of the whole market. If it does not exceed, it usually stems from the problem of statistical caliber. In 2006, there were very few index funds, and most of them had already opened their positions when they were issued, so it is normal for some indexes not to win the market.
