Index Rebalancing: What the Data Tells Us
UBS analysts tested the performance of inclusions and deletions from regular quarterly rebalances between 2000 and 2017 for the ASX 100 and ASX 200 indices.
"We note there is a significant discount to stocks being deleted. As passive investing and benchmarking becomes more prevalent, the 'deletion discount' will likely increase in magnitude," the analysts said.
Here are a few things to note before we dive into the charts around inclusion and exclusion performance:
There are currently 8 full trading days before the effective date (as of Tuesday, 5 December)
As obvious as this sounds, the inclusions join the ASX 200 due to their outperformance or the inferior performance of those about to be excluded
Stocks must meet certain eligibility criteria to be considered for inclusion in the index. This criteria may include factors such as liquidity, market capitalization, and listing requirements.
The below chart shows the median and mean total return of stocks going out of the ASX 200 60 trading days before and after their index exclusion dates against the equal weighted total return of the ASX 50 between January 2000 and August 2017. The relative returns are cumulative and set to 0% on the effective date.
