A Mood Ring for Investors?

The Rationalizer aims at sensing day traders’ stress levels so they can “time-out, wind down and re-consider their actions,” the companies said, according to Reuters. Users wear a device called the EmoBracelet that senses stress and makes an accompanying lighted bowl, or EmoBowl, change color and flicker from yellow to red as emotions become more intense.

Researchers at Philips say home investors often do not act purely rationally. “Their behavior is influenced by emotions, most notably fear and greed, which can compromise their ability to take an objective, factual stance,” they said, Reuters reported.

Although the device is not in production, Geert Christiaansen, chief of business development at Philips Design, says the technology could be used in an array of other products.
