A recent study has found the value of a Hermes Birkin handbag is a less risky investment than buying gold or entering the stock market. The study, conducted by Baghunter looked at the value of the S&P 500, gold and Birkin bags over the space of 35 years and recorded how each value changed.

The stock market returned an average 11.66 percent, gold returned an average of 1.9 percent, however surprisingly the Birkin bag increased in value by 14.2 percent.

"While the luxury market suffers during worse economic times, the ultra-luxury market is impervious to economic factors that can affect other industries, such as high-street retail and stock markets," said Evelyn Fox, founder, Baghunter.

A years-long waiting list has made the Birkin highly desirable, which is why it has performed so well over the study period, however the study was completed by a luxury bag website, and as such are subject to questions surrounding biased results.
