I'm all for retaining earlier Postings, when a Co changes Name, but it otherwise the same/similar.
In this case there appear to be no postings as the new company RELX [REL] has transformed from print ( Reed Elsevier ) - to on-line data-protection DYOR.
A write-up in IC suggests they are hot in California, with a strong grip on ( on-line), fraud prevention. Jan2018 sp was £17 "Buy" and remained "buy" as it slipped to £15 (early Feb2018)..... that was just before the US interest-rate created a stock-sell-off with many World Markets reporting similar jitters.... [REL] hardly slipped to £14.76 - but still offers a poor yield of 2%.

M fool say buy, to much debt for me & poor pay out divi director sells ?1500p
