Please stick with a currency in showing the stock prices of SMT (and possibly other stocks). The prices are inconsistently reported, both in pounds and pence, in the same plot. As a consequence, in just one day the plot spikes up 100 times when the price is reported in pence (=1/100 pounds). That makes the chart unreliable.

This issue appears and disappears randomly. When prices are reported in pence, stick with pence.
