"...this company could sell their accounts receivables at a 80% haircut and buy back 50% of the shares outstanding." Nonsense. For one thing, if a company buys back 50 % of the shares outstanding the pps will soar so much in the process that it is entirely unpredictable how much the compny will have to pay for those shares. For another, a company is only alowed to buy back its shares at a very slow pace.
