Don't think this is a trading stock any more....once u get a company with recurring revenues (including a contract with the NHS), it becomes a hold. Add the dividends and no debt and its a safe stock....all IMHO, dyor.
looked at various valuation ratios
for PRES price to sales was less than 1.5...
price to book value was also low ..do you ever use these values for checking?
Im finding some good examples recently
