Fix wrong handling of stock prices exceeding 1000

[guijdp]

The regex expression to extract the unitary value of each stock doesn't treat the case when unitary stock price exceeds 1000.
Current expression separates the value into 2 matches:
Example: Value = 2,613.00 EUR => Regex Result [ 2 , 613.00 ] which renders stock value = 2 at the end
