Net-Net Stocks (NCAV): Graham's Deep-Value Bargain, Calculated

Benjamin Graham had a name for his favorite kind of bargain: a stock trading for less than the cash and near-cash it held, after paying off every last debt. Buy it, and the factories, the patents, the brand, and whatever profit the business still made came free. He called the measure net current asset value; the market calls the stocks net-nets.

The formula

NCAV = current assets − total liabilities. The point that matters: total liabilities, not just current ones. You subtract long-term debt and everything else on the liability side, so what remains is a deliberately conservative floor. Per share: NCAV ÷ shares outstanding.

A net-net is a stock trading below its NCAV per share. Graham's stricter rule: buy below two-thirds of NCAV, a built-in margin of safety of a third against the assets being worth less than the books claim.

Why it works, when it works

The logic is liquidation, not growth. If NCAV per share is higher than the price, you are, in principle, buying a dollar of liquid assets net of debt for less than a dollar, with the operating business thrown in on top. It is the purest expression of the Graham cigar butt: one last free puff. The margin of safety is not in a forecast, it sits on the balance sheet itself, which is why Graham trusted it through the 1930s when he trusted little else.

A worked example

Illustrative figures.

At 3.50 the stock trades below even two-thirds of its NCAV. You are paying 3.50 for 6 of liquid assets net of all debt, and receiving the business itself for nothing. On paper, a textbook net-net.

Net-net working capital, the stricter cousin

Graham knew not all current assets are equal. Net-net working capital (NNWC) discounts them: cash at 100%, receivables at roughly 75%, inventory at roughly 50%, then subtract all liabilities. Because a dying company's inventory may be unsellable and its receivables uncollectable. NNWC is the more honest floor.

Why so few survive contact

1. The melting ice cube

Most net-nets are cheap for a reason: the business is losing money, and every quarter of losses eats into the very NCAV that made it a bargain. A value trap in its purest form. The asset floor only protects you if the company stops burning before it burns through it. Screen the survivors with a Piotroski F-Score to weed out the ones still bleeding.

2. Asset quality

The book says inventory is worth 50; in a liquidation it might fetch 15. Receivables from a failing customer base may never arrive. Hence NNWC, and hence skepticism about any net-net whose NCAV is mostly inventory.

3. Liquidation almost never happens

You rarely collect the NCAV, because the company rarely liquidates. You are betting that the market re-rates the stock, or the business recovers, or an activist forces the issue, none guaranteed, all slow.

4. They are tiny, and there are few

True net-nets are overwhelmingly micro-caps, and they nearly vanish in a bull market, clustering after crashes and in unloved corners (post-2008, parts of Japan). Graham insisted on a basket, thirty names or more, precisely because any single one can be the trap.

Two Graham lenses, and where ours look

Graham left two ways to value the floor. The Graham Number prices a going concern on its earnings and book value; the net-net prices a business closer to its grave, on liquidation value alone. One assumes the company lives, the other assumes it might not. Both are conservative; the net-net is the more extreme.

Our investable universe deliberately does not fish the deepest net-net waters. The composite that feeds the model rankings excludes the smallest and least liquid names, the very zone where net-nets cluster, for the plain reason that a bargain you cannot buy in size, or sell when you must, is not one we will put a member into. That is the same liquidity caution Greenblatt attached to the Magic Formula. Where a balance sheet is genuinely fortress-like, it shows up in Health, and the lowest decile of Health, the melting ice cubes, lands on The Avoid List rather than in a member's portfolio. The rule that sorts is on the method page, rebuilt every trading day in the ranking, and you can screen the universe yourself on the free stock screener.

The net-net remains the most vivid lesson Graham left: that a price can fall so far below a company's own cash and inventory that the market is, in effect, paying you to take the business. Such prices are rare, usually deserved, and occasionally the bargain of a decade. Telling which is which is the whole of the work.
