Ben Graham's investment strategy was to buy stocks at prices below their liquidation value (net-nets). In the best case, the company survives and the price goes up to meet the earnings power value. In the worst case the company would be liquidated and he would still make a profit (unless the company burns through a lot of cash first).
I know net-nets were a dime a dozen in Graham's time and are pretty scarce these days, but, if I were to try out his strategy, I'm wondering how liquidation would be treated. What happens on quantopian when a company goes under and is liquidated? Is quantopian aware of how much the common stock holders would have gotten, does the value just disappear, or is the stock automatically sold before the company goes under?
