You can't, your business strategy has to reflect stonks go up. If your funders are all thinking like stonks go up and you try to build a sustainable YoY profit generating business, you aren't producing a risk reward curve attractive in that environment, and thus won't get funded.

What if the business plan reads something like this: When stonks go up, we hire, and when stonks go down, we fire. That does not seem stupid.

It still sucks to be fired. But the alternative world where we avoided firing at all costs, would mean not as many people getting hired when stonks go up.
