Although the vast majority of investors would take the former view, the message delivered by part of the financial services industry through the media is that the key to wealth management is worrying about all that stuff.
The upshot is that most people start believing that they need this paraphernalia to invest well. And some do have a few successes. But inevitably they end up underperforming the market through bad stock calls, chasing last year's Big Thing, running up big costs or failing to diversify.
Funnily enough, investment is one area of life where constant hard work and minute research day to day don't actually pay dividends.
In contrast, the people who succeed don't trade much. Instead, they concentrate on getting their asset allocation right, staying diversified, riding the ups and downs and keeping an eye on costs and taxes.
Interestingly, those are all things that you can control. "Busy" investors, by contrast, spend lots of time and money on research that can be rendered redundant by unforeseen economic, corporate or political events.
Even the busiest investors – with all the latest software and charting tools and fundamental alert – can still get blindsided by the unexpected. That is the nature of markets. They are unpredictable.
Even in times of apparent plain sailing, hyperactive investors can do themselves a disservice. All that tactical trading is expensive – in initial outlay, and in the higher turnover the activity generates.
Of course, this lesson applies not only to individual investors but to professional fund managers.
The difference is that busy managers can pass back the costs to their research and constant trading to end investors.
The wonder is that people don't seem to draw a link between the higher fees that busy managers charge, and the actual returns they deliver, an irony noted by Anthony Gallea, author of Contrarian Investing.
"Investing is a strange business," he wrote. "It's the only one we know of where the more expensive the products get; the more customers want to buy them."
Of all the determinants of any fund's performance, expenses are among the most important. And remember, they are deducted directly from whatever returns the manager generates. Plus, their effects compound over time.
So, it seems that successful investors are not necessarily busy investors – just smart ones with lots of time!
