SIPP update continues

I've recently decided to bite the bullet and close the book on my ill-fated purchase of XChanging (XCH). As such, I've sold off my entire 3000 shareholding, recouping (after costs) £3,087.43. This has resulted in a loss of just under £2,000 or approx 40% of my initial investment.
Disappointingly awful.

Pending the adjustment of my OPAY shareholding - which should follow once the company is quoted on the FTSE250 - I've decided to commence updating my SIPP.  This is in-line with the criteria I have set myself when reviewing SIPP performance earlier this year, ie:-
1) Investment companies to have a market value between £500m - £3,000m
2) Investment companies to have a yield of at least 3%.
3) Investment companies to be without significant debt, or able to cover debt from cash reserves (if this does not make sense that is because I am NOT a trained financial analyst).

As such, taking advantage of the monies recouped from the sale of XCH, I have been able to make initial purchases in a couple of companies:-
Laird (LRD): 190 shares @ 400
and
RPS Group (RPS): 330 shares @ 229
I have also brought the shareholding in BRSC up to 10% of the SIPP value, approx £8,300, by purchasing another 140 shares @ 939.
