In addition to the crystal clear post by Henrythecat.
Math34, I would stress that the UT is not a solitary person making a single trade to buy x number of shares. It could be tens, hundreds or thousands, of buyers and sellers, it does not matter.
Also note that trades are often wrongly displayed as a buy when it was really a sale, vice versa and sometimes trades are not displayed at all.
Regarding 'pretty confident': I am confident in Rolls Royce as a solid company with great prospects and I bought more shares at 108p near the end of the day.
