It's not clear what "black swan readiness" means. In terms of a company having a healthy balance sheet, there are many well known metrics that can signal that a company is at higher risk of bankruptcy. E.g. acid test, interest coverage ratio, Altman z score: https://en.m.wikipedia.org/wiki/Altman_Z-score https://en.m.wikipedia.org/wiki/Altman_Z-score The Altman Z score was defined over 50 years ago and can be approximately competed using the standard accounting data that public corporations are required to report to investors. I'll push back a bit: there are ways of measuring/ estimating some of these. If you read an old school book on value investment, some of these ideas may be covered. Why not use them when considering how to invest wealth?
