Most (if not all) of those 5 stocks are high dividend paying shares - I hold Aviva, GSK and LGEN in my dividend income portfolio.
Current dividend yields:
Aviva - 7.67%
GSK - 4.4%
Legal and General 8.78%
Sainsbury’s 4.91%
Unilever 3.74%
Most people hold these for dividends, not for capital growth so it really depends on what you want from your shares. The income can always be ploughed back in to the same share to grow the dividend but if you’re looking for capital growth, perhaps it is worth just selling and lumping it all in a global ETF like VWRL.
Good luck whatever you decide
