I do not play the stockmarket, but I do invest in shares.
The first shares I acquired, I acquired when my employer, British Gas was privatised. I got about 100 free shares and could buy another 2,000 at a preferential rates, so I did.
Those shares have served me very well. The company was later divided into 3 seperate companies: oil and gas, transmission and distribution and domestic distribution (Centrica). The first two were taken ove and bought my shares and I still have my shares in Centrica.
Since then I have bought shares in four or five other companies, all of them big international companies in robust markets. I also have investments in different funds, these are a basket of shares chosen by the fund managers, much as pension funds invest our pension savings.
There is nothing mysterious or magic about investing in stocks and shares. You just need to take an interest in current political and world affairs and get in the habit of reading the business section in one or two newspapers.
One DH's aunts, a teacher married to a chicken farmer, started doing this after she was widowed in her 40s. The £20,000 capital she received from the sale of the farm business after her DH's death, had grown to over £500K by the time she died 30 years later, plus of course dividends. All done by reading papers and being aware of what was happening in the world around her.
