Round-up of the biggest UK insider moves

Late May 2026 has produced one of the more comprehensive UK director dealings windows in recent memory. The Sharecast Director Dealings index records buy entries across FTSE 100 (BAT, Centrica, Auto Trader), FTSE 250 (Caledonia Investments, CVS Group, Greencore, Jupiter Fund Management, Convatec, Genuit Group), AIM (Naked Wines, Pharos Energy, Tapir Holdings, NB Equity/">Private Equity Partners) and trust (Baillie Gifford Shin Nippon) names, alongside sell entries at Ashmore Group, Luceco, Card Factory, Hill & Smith, Reabold Resources and Star Energy Group.

Named-director disclosures provide the most analytically useful data. On the buys side: Scott Morrison at CVS Group (987 shares at 1,269.68p, £12,531.75), Jack Pailing at Naked Wines (52,750 shares at 75.00p across two trades, £39,562.50), Katherine Roe at Pharos Energy (5,355 shares at 27.50p, £1,472.63), Abigail Rotheroe at Baillie Gifford Shin Nippon (7,438 at 160.44p, £11,933.53) and Philip Johnson at Tapir Holdings (69,800 at 3.50p, £2,443.00).

On the sells side: Ross Glover at Star Energy (289,541 at 16.00p, £46,326.56) and Frances Ward at Star Energy (60,475 at 16.00p, £9,676.00).

Biggest single named-director buy: Pailing at Naked Wines

By aggregate value, Jack Pailing's purchase of 52,750 Naked Wines shares at 75.00p for £39,562.50 is the largest named-director buy in the late-May 2026 reporting window. The two-transaction execution at the same price level on 27 May 2026 reinforces the deliberate nature of the personal Capital commitment.

Naked Wines has been one of the more discussed UK turnaround stories in recent years, and a personal capital commitment of nearly £40,000 by a director at a defined price level provides a useful anchor for investors who follow the equity story.

The transaction does not necessarily indicate a change in Naked Wines' fundamentals, but at this size it is the most material named insider buy in the window.

Biggest single named-director sell: Glover at Star Energy

By aggregate value, Ross Glover's sell of 289,541 Star Energy shares at 16.00p for £46,326.56 is the largest named-director sell in the late-May 2026 reporting window. The disposal was paired with a smaller sell by Frances Ward (60,475 shares at 16.00p, £9,676.00) at the same price.

Combined, the two Star Energy disposals total 350,016 shares for approximately £56,002 in proceeds, anchored at a single 16.00p price level. The disclosure is sufficient to anchor a discussion of the transaction, but it does not on its own justify a wholesale change of view on the stock.

Investors should read the underlying RNS to understand the directors' residual holdings and the broader strategic context.

Most active single-stock buyer pattern: Pailing at Naked Wines

Naked Wines is also notable for the most active single-stock buyer pattern in the window, with both of the named Pailing transactions occurring on the same day and at the same price. The pattern suggests a clear decision to commit personal capital to the stock at a specific level on 27 May 2026.

When a single director executes multiple transactions at the same price on the same day, the deliberateness of the commitment is reinforced. The pattern can also reflect the mechanics of executing larger total volumes in smaller tranches.

Either interpretation is consistent with a positive sentiment signal for Naked Wines, although the transaction does not by itself signal a change in fundamentals.

Most active single-stock seller pattern: Luceco

Luceco is the most active single-stock seller pattern in the window, with four sell entries on 26 May 2026 and a further entry on 27 May. While the line-level RNS detail is not enumerated in the source reviewed, the sheer number of entries at the small-cap stock makes it a stand-out feature of the Sell-Side data.

Multi-row sells on a single day are often consistent with several PDMRs transacting in a single dealing window. The pattern attracts attention, but it does not by itself indicate a change in fundamentals.

Investors should consult the underlying RNS for the directors, share counts and prices, and consider the disposals alongside the broader operational and macro backdrop.

Broader insider moves to note

Beyond the headline named transactions, the round-up captures notable Buy-Side activity at Auto Trader, Caledonia Investments (two entries on 27 May), CLS Holdings, Greencore, Jupiter Fund Management (two entries on 27 May), BAT (two entries on 26 May), Centrica (two entries on 26 May), Convatec Group (one entry on 26 May plus a separately reported CEO purchase on 27 May), Genuit Group (two entries on 26 May) and Fragrant Prosperity Holdings.

On the sells side, the round-up captures Ashmore Group (one entry on each of 26 and 27 May), Card Factory (two entries on 26 May), Hill & Smith (one entry on 26 May) and Reabold Resources (one entry on 26 May).

Together, this is one of the broader UK director dealings windows in recent memory and is worth integrating into ongoing Investment reviews.

Risks and opportunities of the biggest moves narrative

Risks include over-extrapolating from individual large transactions and missing fundamental drivers behind each company. A single big buy or sell can shape sentiment in the short term but does not necessarily predict longer-term operational outcomes.

Opportunities lie in identifying names where the biggest insider moves align with other constructive or cautious inputs. The named buys at Naked Wines, CVS Group and Pharos Energy and the named sells at Star Energy are particularly useful candidates for follow-up.

Above all, the transactions do not necessarily indicate a change in fundamentals at any of the named companies.

A balanced conclusion on the round-up

The director dealings round-up for late May 2026 captures a particularly rich set of UK insider moves across both buys and sells. Named-director disclosures at Naked Wines, CVS Group, Pharos Energy, Baillie Gifford Shin Nippon and Tapir Holdings on the buys side, and at Star Energy on the sells side, provide concrete anchors for analysis.

Broader activity across FTSE 100, FTSE 250 and AIM names adds breadth to the dataset, supporting a comprehensive review of UK equity stories. The biggest moves narrative is most useful as a prompt for targeted analytical work rather than as a stand-alone trading signal.

Used with discipline, the round-up supports a more informed reading of UK insider sentiment without substituting for the fundamental work that drives long-term returns.
