For those contemplating investing in the stock market or who want to increase their knowledge, Rodney Hobson's primer Shares Made Simple is out in a heavily-revised third edition. Talking to Simon Rose, Rodney explains why cash is actually riskier than the stock market over the long term. He emphasises the importance of dividends, points out that stock market investing has never been simpler than it is now and explains why he prefers investing directly rather than through funds.
