Book Recommendedations: Learning About the Stock Market

Hi All,

I am a relatively amateur investor. I work within financial services so I have developed a basic understanding of finance and investments however admittedly still know little about the underlying theories behind the stock market/shares.

I am looking for advice on a good couple of books I can look at purchasing which will provide me with an introduction to stock markets and investments including different approaches to FA and TA and other strategies used when researching stocks.

Any suggestions?

Thanks in advance.
