This looks like a classic real options problem. Essentially, each decision is an option which will be chosen strategically: the owner will chose a vector of actions from all possible actions, $A\in\mathcal{A}$, that maximizes expected utility given the distributions of key variables and outcomes.
If the owner is well-capitalized, maximizing the expected ...

Adding to the list of products mentioned in the comments: zero-coupon bond options have analytic solutions too (in terms of noncentral chi-squared distribution function), and caps and floors, when seen as portfolios of zero-coupon bond options (see Brigo and Mercurio book).

DataFrame df with a few random returns that I made up:
import pandas as pd
df = pd.DataFrame({'rets': (.5, .5, .4, .3)})
Add cum_rets column:
df['cum_rets'] = (1 + df['rets']).cumprod() - 1
Add inv_cum_rets colum:
df['inv_cum_rets'] = ((1 + df['cum_rets']) / (1 + df['rets'])) - 1
If you want it lined up with your original returns, just shift it up 1 row

Maybe a "statistical mechanics" approach - paper at https://arxiv.org/pdf/1907.04925.pdf and code at https://uk.mathworks.com/matlabcentral/fileexchange/72000-canonical-ensemble-for-time-series
From the paper abstract:
"This consists of a statistical mechanical approach - analogous to the configuration model for networked systems - for ...
