Depends.
what is the net cash position of CGB? have a look at the Half yearly report and calculate it.
then make an estimate on how much cash they burned through in the Jan-Mar quarter in 2020, or 2021. pick the lessor.
now using that, calculate what their net cash position is likely to be as at 31st of March 2022.
If your result comes up above the market cap,, some people would use that as justification to make a trade. But if it comes in below.. well some people would stay well away from it.
Your trading decision would depend on what result you get, and if you are comfortable making a trade on such a result.
