ASOS (ASC:AIM) is an online-only fashion retailer targeted at the social media-savvy ‘20-something demographic’. It remains a major beneficiary of the structural spending shift online.

The company continues to deliver rapid overseas growth and impressive UK sales progress at a time when domestic UK apparel retailers are struggling.

ASOS recently upgraded (12 Jan) full year 2017 sales growth guidance to a 25-30% range following a strong four months to the end of December, giving the share price another upwards nudge.

A smaller pure-play online peer is Boohoo.com (BOO:AIM). Its meteoric rise reflects similar trends. Stellar growth is being delivered at home and overseas, including in the notoriously tough-to-crack US market.

Analysts recently upgraded their earnings estimates yet again following a pre-close update (28 Feb) from consistently cash generative Boohoo, revealing continued positive momentum in the final two months of its financial year.

Premium carbonated mixers star turn Fevertree Drinks (FEVR:AIM) has rapidly become one of the junior exchange’s biggest businesses by market value. It was worth £154m when joining the stock market in 2014. The value has since increased 11-fold to £1.7bn.

Fevertree is riding a renaissance in the popularity of gin in particular and securing market share gains with supermarkets, bars, hotels and restaurants.

A big overseas earner, Fevertree also has an asset-light, outsourced production model that means it is very cash generative and pays a progressive dividend.
