Financial speculation refers to high-risk stock market activities. These activities are similar to gambling. The researchers used data from a large-scale, population-based study to estimate the prevalence rates of financial speculation in Canada. They also explored the demographic and health profile of people who engaged in financial speculation, and the link to gambling. The national prevalence rate was 3.6%, with Alberta having a higher rate than other provinces. People who engaged in financial speculation were mainly men between 30-49 years old, with higher education and household income. They were more likely to drink regularly and smoke occasionally, but rate their health and life satisfaction higher. They gambled more frequently, especially on sports and casino table games. Gambling problems were also more common among these participants.
