Felix Salmon sees amateur stock-picking as a male-dominated hobby. He figures that stocks might cost the average trader $5000 a year:
I know people who can spend $5,000 on a single bicycle. If you’re into classic cars, $5,000 is nothing. And similarly, if you’re skiing or flying around in small planes or even just taking a luxury vacation once a year, $5,000 can be a relatively modest sum for a reasonably affluent person. And none of those hobbies come with the extra thrill of dreaming that they could end up being highly profitable.
One thing I would note, though: from a financial-media perspective, you’re limiting yourself enormously if you spend too much time chasing that small group of hobbyists — especially if you’re not trying to sell them subscriptions. Look at the enormous number of websites which put stock tickers next to company names, so that the hobbyists can see exactly what the stock in question is doing that day. It makes the site seem as though it’s targeted at silly males, rather than at a broader, smarter audience.
