RE: SHARE PRICE INFORMATION28 Mar 2013 09:13
Something to do with LSE price being the mid price between buy and sell prices, wheras for instance Yahoo where I keep my portfolios shows the value of the last trade. Using the LSE method the mid price can change up/down based on MM quotes or even mistakes in the system, without a share changing hands. I prefer to use a "last trade" price, at least it's real, and go from there if I want to dig deeper.
This is all with my limited knowledge of these things.
