The simple story
Here at the Fool, we've long cautioned investors to keep a close eye on inventory levels. We think a quarterly checkup is key to spotting potential problems, especially with seasonally dependent, fashion-oriented retailers like Coach
That's because too often, the only way to get rid of stale merchandise is to put it on sale, thus hurting profitability. In extreme cases, companies may even need to write off those purses and chips entirely, and that involves taking a near-complete hit on the goods and -- rumor has it -- sending them out to be ground up into meat sauce for crooked school-lunch programs.
Basic guidelines
To keep a handle on inventories, we often use a simple rule of thumb: Measured across comparable quarters (year-over-year), inventory increases ought to roughly parallel revenue increases. Simply put, if inventories grow 35%, we hope that sales will have grown that much as well. Of course, if a company can reduce its inventory growth relative to its sales growth, that might be preferable by freeing up money that's essentially sitting around fallow on the shelves. Hey, even bank interest is better than no return at all.
Conversely, if inventory bloats to a rate beyond the growth in sales, we expect a darn good explanation.
Exception to the rule
Fools should be aware that there's one type of inventory bulge we actually like to see. In fact, it can be a key to identifying a potential Hidden Gem before the Street shows up with its shovels and tries jumping our claim. This is something we call "positive inventory divergence," which is a concept taken from one of our favorite books, Thornton O'Glove's Quality of Earnings.
There are different kinds of inventory: raw materials, works in process, and finished goods. To take a hypothetical example, if we make ovens, like Hidden Gems' 250%-plus-returning superstock Middleby
Here's the kind of bloating inventory that can be a clue to future glory. If Middleby is ramping up for increased demand it sees -- but may not have reported to the Street -- it may very well be growing certain parts of its inventory at a rate faster than sales. We would expect to see these healthy bulges in the area of raw materials and works in process. To go one further, if this is a company that is subject to continuing increases in commodity prices, we might also cheer its decision to buy extra raw materials while the prices are still lower than what it expects to have to shell out in the future.
If, on the other hand, the bloat comes in finished goods, this might be a sign that expected sales haven't materialized, and management has some 'splaining to do.
Here's Middleby's inventory story as of the April quarter of 2005 and 2004.

As Middleby shows (as of the April quarter of this year), what looks at first like an oversized inventory spike is actually a bit more complex. Although total inventory growth outran revenue growth by a difference of nine points, a very healthy chunk of the increase came in raw materials. Finished goods also piled up a bit more quickly than revenues did, which should have the folks at the dedicated Hidden Gems board mulling over the reasons.
Foolish bottom line
When you're scanning your quarterly earnings reports, remember that many of the numbers mask situations that are more complex than they appear. When in doubt, listen to the conference call, give investor relations a jingle yourself, and make sure to check back when the quarterly report is filed. What at first looks like a problem may indeed be a sign of good things to come.
