News that legendary investor and one-time "Bond King" Bill Gross would retire from investing after nearly five decades in the asset management business - a storied career where he built PIMCO into a giant in the industry while managing its Total Return bond fund, the largest mutual fund in the world - was perhaps the biggest investing headline during a day where the start of the Chinese lunar new year, a lull in US earnings and the national Super Bowl-inspired hangover day led to a dearth of news.

And in a coup for Bloomberg TV, Gross appeared on America's third most-popular financial TV network for an exit interview of sorts, where the manager of the Janus Unconstrained bond fund, which has persistently posted subpar returns since he jumped ship from PIMCO in 2014, delved into some of the biggest market topics of the day, while touching on some of his biggest regrets in recent years.

The conversation began, as most conversations with high-profile portfolio managers do these days, with a discussion of Gross's views on the long-term impacts of QE, and whether Gross believes central bankers 'got in his way' during the past few years.
