If, that is your response to being kicked out of the ASX 200, then I would rethink investing in the capital markets.

Big funds (super funds e.g.) hold ASX 200 shares and many invest proportionally across the ASX 300 200, 100, 50 and 20 for varying reasons (yield or growth or both etc.). When a company is removed from one of those lists the funds will re balance their portfolio and that leads to ... guess what ... some more selling.

How are ASX 200 companies selected?

Constituents are selected by a committee from Standard & Poor’s (S&P) and the Australian Securities Exchange (ASX).
All companies listed on the Australian Securities Exchange (ASX) are ranked by market capitalisation. Exchange traded funds (ETFs) and Listed Investment Companies (LICs) are ignored. The top 200 ASX stocks that meet minimum volume and investment benchmarks then become eligible for inclusion in the index.
Rebalances are conducted quarterly in March, June, September and December. If a significant event occurs (e.g. delisting, merger, etc.) an intra-quarter rebalance may be conducted. A minimum of two business days’ notice is given to the market.
