I like to keep my ‘Newcastle Stock Exchange’ on the stocks app on my phone even though I don’t have any shares in them, just to keep track of how the PLCs in my hometown are doing. Greggs, Go-Ahead, Sage, Bellway, Virgin Money, Grainger. So I’d also be another vote for Greggs.
Otherwise I’d like to see some less common ETFs away from the usual FTSE 100, S&P 500, Nikkei 225 ones. Things like INDA or any ETFs to track India would be big ones for me. Some people may even like ones like SHE, which invests in companies judged to be doing well on gender equality.
