John Hancock Financial, the Boston financial services company, recently administered an “investment literacy quiz” to nearly 1,100 consumers, and the results were not pretty --- nearly half scored a failing grade, the company said.

Just 11 percent of investors scored an ‘A’ on an eight-question investment literacy quiz. The quiz was part of the John Hancock Investor Sentiment Survey.

The quiz included questions about asset allocation, index funds, and the tax treatment of Roth IRAs.

“Investors were able to select correct answers to questions about financial concepts or product definitions, but most exhibited significant knowledge gaps.” John Hancock said in a press release. “When it came to correctly answering a question about an optimal retirement savings strategy, knowledge declined further, with only 37 percent able to choose the correct answer.”

This online survey was conducted for John Hancock by independent research firm Greenwald & Associates in mid May. To qualify to take part in the survey, respondents were required to participate at least to some extent in their household’s financial decision-making process, have a household income of at least $75,000, and assets of $100,000 or more.

John Hancock Financial is a division of Manulife Financial, a large Canada-based financial services group.
