Galiform (GFRM, 19p), the UK kitchen builder and joinery company, announced last week (26th March, londonstockexchange.com) that the CEO Matthew Ingle and the CFO Mark Robson had substantially increased their holdings.

Ingle bought 870,000 shares at 15p and 17p, taking his holding to 2.7m shares, and Robson bought 403,000 shares at 17p, taking his holding to 930,000 shares.

Good news?

If you look at historic cases of two non execs and no non execs transacting, the average relative underperformance since the transaction is -8%. If a non exec joins them, then the historic performance jumps to + 16% (followthedirectors analysis of transactions of 350 directors over last 14 months-unpublished).

I got this one completely wrong in April last year, when Robson bought 132,000 shares at 77p. The stock is down 73% since then, a relative underperformance of 33% (see ‘Housebuilders at a standstill, but galiform directors buying’).

It may simply be that Galiform directors, and the share price, are playing catchup with Barratts. We saw Barratt (BDEV, 126p) directors buying shares in November and December. Barratt shares are up 69% absolute or 60% relative since our comment on January 15th: ‘Barratt- look for buying opportunities.’

I see the Galiform directors purchases as reinforcing a positive view for the housebuilding sector overall.

View on Galiform: Positive.

Reiterate Positive view on Barratt Developments.

Signal strength: Weak (would upgrade if we see a non exec buying shares)
