I came across this great seekingalpha article today, looking at the work of noted stock market historian Roger Ibbotson.
The thesis is simple: that Popular stocks perform least well, while little-traded, "unpopular" stocks perform best over the long-term.
This is a great chart from the above article that illustrates the outperformance neatly:

Extending this concept to the UK stock market, which stocks are least "popular", as judged by average yearly share turnover?
UK stocks out of the FTSE All-Share index that come up as having the lowest proportion of their market cap. traded over the last 12 months include:
Euromoney Institutional Investor (LON:ERM)
Town Centre Securities (LON:TCSC)
Daejan Holdings (LON:DJAN)
NMC Health (LON:NMC)
Goodwin (LON:GDWN)
SThree (LON:STHR)
Laura Ashley Holdings (LON:ALY)
Mountview Estates (LON:MTVW)
A.G.Barr (LON:BAG)
Management Consulting (LON:MMC)
Interestingly, these names also overlap with another well-known stock market outperformance phenomenon, that of the outperformance of companies with large founder or family shareholdings.
