The hunt for shares which are riding the wave of momentum can be a good starting point for investors - it's certainly worked for those who have followed the phenomenal growth of US tech companies in the last few years.
To help you find the shares which are riding momentum (both positive and negative), every week we publish a list of shares that have hit or are very close to hitting a new 52-week high or low. The tables include details of shares which have prices within 3 per cent of either a year high or year low.
Why does momentum matter?
