The secret to good investment writing is the same as that to good investment decisions. Don’t follow the herd, shut out market noise, and think for yourself, says Fiona Rintoul. Are you a good writer? This is a tough question to answer. We recognise good writing when we see it, but it can be hard to define what makes it good. Learning to spot the hallmarks of quality in other people’s writing – concision, variety, authenticity – is an important step towards becoming a good writer yourself.
