Yes, I started with shares I was given/offered at a discount when my employer was nationalised. I made a fortune on them.
I have since bought shares in other companies. Some have done well some have bombed. I bought shares in my then bank - Royal Bank of Scotland - and also I kept some shares in BT that I inherited, these both sank like a lead balloons. But others have been taken over and I have been bought out at a profit.
DH has invested in penny shares for several decades now, inspired by an aunt who turned £11,000 in 1975 into £500,000 by the time she died 20 years later. He too has had successes and failures, but overall has done better than inflation.
