# Cheap, or broken?

_A share that has just fallen 40% is either a mispriced business or a deteriorating one. Here is how I try to tell the two apart._

Someone once told me one of his holdings had fallen about 20% in a week, and asked what he should do. I can’t tell anyone what they should do but my answer was that the week had told him almost nothing. 

In the short term, share prices are very noisy and move around for all sorts of reasons that have nothing to do with the business underneath them. The value of that company had almost certainly not changed in five trading days. Only the price had.

That is the easy case, and it is also a trap of its own, because it tempts you into a comfortable rule: ignore the fall, the value is intact, the market is being silly. Sometimes the market is being silly. Sometimes the fall is the first honest thing the share price has done in a long time, and the business really is worth less than it was.

The whole skill of [Decision 03](https://www.noisecancelling.co/learn/is-it-the-right-price), judging whether something is the right price, lies in telling those two situations apart.

## You cannot answer it without a prior view

You cannot answer it after the fall if you had no view of it beforehand. To know whether a share is cheap, you have to know roughly what the business is worth: its intrinsic value, the considered figure you would put on it from its cash flows, its returns and its prospects, independent of what the screen says today. _(Neil in the margin: Intrinsic value is what a business is genuinely worth on its fundamentals — future cash flows discounted back — as distinct from its market price. The whole exercise assumes you can form such a figure independently; sceptics argue it's precise-looking guesswork, which is why Neil stresses doing it 'in the calm'.)_

Form the valuation first, in the calm, and the fall becomes new evidence to test it against. Without that calculation, a sell-off that then prompts action is no better than a guess. With it, the fall becomes a precise question. The business is now priced as if something specific is true. Is it?

## Has the price changed, or the value?

That’s the question I keep coming back to, and it sorts almost everything. 

A change in the price with no change in the value is the definition of an opportunity. A change in the value, where the price has merely caught up to it, isn’t.

I look at four things to help me differentiate between these two different situations.

### One: has the thesis broken, or just the mood?

Every position in a portfolio should be the product of balanced analysis that enables an investor to identify a valuation anomaly. But in a dynamic world, things change and sometimes quite radically, and when they do, financial markets react, often instantaneously. 

Deciding what to do next is not easy because it involves triangulating several different things. First, if the change has affected the underlying value of a business, a reappraisal is required. Once that’s done, the investor then needs to compare the new valuation with what’s changed in the market, the price, in other words. 

Often, market reactions are exaggerated and share price movements up and down overcompensate for the new information. Herein lies a trap for the unwatchful. Reacting to the news, even when it might be significant, is a mistake before some understanding of what it means for value. 

For example, bad news that might have impaired a company’s value by 20% but which results in a 40% fall in its share price presents not a selling opportunity but quite the reverse, even though the news is clearly not good.

### Two: Is the balance sheet still standing?

Financially strong businesses with robust balance sheets can withstand the slings and arrows of a volatile and unpredictable world, and businesses with stretched financials and excessive leverage are uniquely vulnerable to unpredictable events. 

That’s why when bad news arrives, as it inevitably will for all businesses, a good look at a company’s balance sheet will tell you a lot about how damaging that event will eventually be and how quickly the business can move on from the setback.

### Three: Is this the bottom of a cycle, or a structural decline?

A cyclical business at the bottom of a cycle can look like a structurally declining one. Both show falling profits, a depressed rating and a grim set of headlines. The difference is what happens next.  _(Neil in the margin: 'Rating' here is City shorthand for a valuation multiple — typically the price-to-earnings ratio. A depressed rating means the shares trade at a low multiple of profits, which can equally signal a bargain or a market that's correctly pricing decline.)_

A housebuilder in a period of high interest rates has demand that is delayed, not destroyed. A business whose customers are leaving for a rival and not coming back is in a different position altogether. 

Judging which is which requires understanding the industry rather than the share price, because the share price cannot tell you whether the weakness is temporary or permanent.

### Four: Is the cash still there?

Profit is an opinion; cash is a fact. When I am trying to understand how mispriced a company might be, the cash flow statement is generally the most reliable place to look. 

A business whose reported profits are holding up while the cash is quietly draining away is usually a business whose troubles have not yet reached the income statement. Falling cash conversion, the share of profit that actually turns into cash, ahead of a falling share price, is one of the more reliable early signals that the value, and not just the price, might have changed. _(Neil in the margin: Cash conversion measures how much of accounting profit becomes actual cash. It matters because profit rests on judgement calls — revenue timing, depreciation — whereas cash is harder to flatter, so a widening gap between the two is often the first honest sign of trouble.)_

## A worked example of Decision 03

Take Garrow Instruments, a fictional mid-cap company I am using purely to illustrate the method. Suppose its shares fall 45% over a few months after a profit warning. On the screen, it looks like the bargain of the year: half its old rating, a yield suddenly into double figures. _(Neil in the margin: Dividend yield rises mechanically as the share price falls, so a double-digit yield usually reflects a collapsed price rather than generosity. It's frequently the market signalling it doesn't believe the dividend will survive — a classic value-trap tell.)_

**Run the four tests:**

1. The warning turns out to be one large customer delaying a contract by two quarters, not cancelling it, so the thesis that Garrow’s instruments are specified into long-life industrial kit is intact. 

2. Net debt sits below one year's operating profit, with no near-term refinancing, so the balance sheet can wait.  _(Neil in the margin: This is the net debt to profit ratio, a rough gauge of leverage and how quickly borrowings could be repaid. Under one year's profit is comfortably conservative; the later scenario's 'three times' is the level where lenders and refinancing start to dictate terms.)_

3. The end markets are cyclical and depressed by a pause in capital spending. 

4. And cash conversion through the wobble holds in the nineties, so the profits are real. On that reading, the 45% fall is, in my view, a change in the price, not the value, and a reasonable example of a mispricing.

**Now change the facts:**

1. The warning is not a delay, but the customer is moving to a rival’s component, cash conversion has been sliding for a year.

2. Net debt is nearer three times profit, with a refinancing due. 

Same 45% fall, same cheap-looking screen, and now every test appears to be pointing the other way. The thesis, if not broken, has taken a severe dent, and the balance sheet requires a relatively quick solution. 

This could be a value trap, and the discount is not automatically an opportunity but a signal that the market has begun, arguably correctly, to price the future. The price has moved because the value has.

The two Garrows are indistinguishable on a stock screen. They are not difficult to tell apart once you have done the work. **They are impossible to tell apart if you haven’t.**

## What it changes

There is no information in a falling price beyond the fall itself. The market is telling you that more sellers than buyers turned up, not why, and certainly not whether they were right. The only anchor I have ever trusted is valuation: a business worth more than its price will, in my experience, generally be recognised given time, and a business worth less than its price will, given time, be found out. 

A 40% fall does not tell you which of those you are looking at; instead, it’s telling you to **go and find out**.
