January Retail Trading Updates: How to Read Them After Christmas

The decorations are barely down before the statements start arriving. Between the first and third week of January, listed UK retailers publish festive trading updates, the British Retail Consortium releases its monthly sales monitor, and the ONS publishes retail sales for December. Together they offer the clearest picture of how households actually spent in the run-up to Christmas.

The difficulty is the language. "Strong like-for-like growth" and "a record Christmas" mean very different things depending on the period measured, the base compared with, and whether growth came from more sales or simply higher prices. Here is how to read the numbers with a clear head.

What lands in January, and when

Food retailers tend to go first, often in the first full week back, with short statements covering a handful of weeks. Fashion, homeware and general merchandise retailers follow mid-month, and some use the occasion to update profit guidance for the year just ended.

Three things matter before you read a single figure:

• The period covered. Some updates cover six weeks, others the 13 weeks to early January. A longer period smooths out weather and calendar quirks; a shorter one can flatter or punish a retailer depending on when Christmas fell.
• Whether it is audited. Trading statements are not. They are management's numbers, published quickly and often sparingly.
• What is being compared with what. Find last year's equivalent statement. It is the only fair benchmark.

Like-for-like sales: useful, but slippery

Like-for-like (LFL) sales measure stores and channels that existed in both periods, stripping out the effect of new openings, closures and, often, refits. That makes them a decent proxy for underlying demand, which is why they dominate the headlines.

The catch is that no two retailers define them identically. Some include online sales, some report them separately. Some count a store as comparable only after twelve months of trading. Most quote the figure excluding VAT. A 4% LFL rise at one company is not the same animal as a 4% LFL rise at another.

Five questions to ask of any LFL figure

1. What was happening in the same weeks a year earlier? A weak base makes any recovery look impressive.
2. Is the growth in value or volume? If prices rose faster than sales, shoppers bought less.
3. Did online growth simply take sales from stores the same company owns? Check total sales too.
4. Was it bought with discounts? Look for any comment on gross margin.
5. Does the period include the weeks that matter? A retailer with a strong December but a poor November may choose its dates carefully.

Why "a record Christmas" usually means very little

In cash terms, most large retailers post record festive sales most years. Inflation and new space do much of the work. The interesting question is not whether sales were higher, but whether they were higher enough to cover rising costs — wages, energy, freight, business rates — and still leave a profit.

Calendar effects matter too. The number of shopping days between Christmas and the new year shifts year to year, and so does the position of Christmas Day in the week. When Sunday trading hours apply to Christmas Eve, a chunk of trade moves into an earlier week. A retailer can look as though it had a terrible December when it really had a slightly odd one.

Reading a profit warning

Some updates come with bad news. The wording tells you a lot about the underlying problem, and it helps to sort warnings into rough types:

• Sales shortfall. Shoppers did not turn up. Usually a demand or range problem, and often the most serious.
• Margin squeeze. Sales held up, but discounting or cost inflation ate the profit. Common in competitive sectors.
• Cost shock. An external change — a wage floor increase, a tax change, a currency move — hit the numbers.
• One-off. A warehouse fire, a systems failure, a write-down. Painful, but not necessarily a sign the business is broken.

Note the difference between new guidance and a restatement of old guidance, and whether the retailer blames itself or its market. If several companies in the same sector warn in the same fortnight, the problem is probably the consumer, not the management.

Do not read one company in isolation

A single trading statement is an anecdote. The British Retail Consortium's monthly monitor and the ONS retail sales figures give the sector-wide view, though both publish with a lag and measure slightly different things. Footfall counters and bank card spending trackers add texture.

Cross-checking matters. If one fashion retailer reports a difficult December while the wider data shows modest growth, ask what it did differently. If everyone reports the same pressure, that is a market story.

A checklist for the first fortnight

1. Write down the exact period each update covers.
2. Find the same period a year ago.
3. Separate total sales from like-for-like sales.
4. Look for one line on gross margin. If there is none, be suspicious.
5. Read the outlook paragraph before the numbers.
6. Compare at least three companies in the same sector.

Using it without overreacting

Festive trading updates are a snapshot of a few unusual weeks. They can tell you whether a retailer's ranges, prices and operations are working, and whether costs are under control, but they rarely settle a long-term view on their own. Wait for the full-year results, which include the balance sheet and cash flow, before drawing hard conclusions.

If you are a supplier, use the statements to judge who is growing and who is discounting, and think about credit terms accordingly. If you have savings invested in retail shares, remember that January price moves often overshoot in both directions, and that nothing here is personal financial advice; for decisions that matter to you, speak to an adviser authorised by the FCA.
