Fitbit surges, Facebook diversity, and Rand Paul's tax plan

The Dow Jones Industrial Average (^DJI) and S&P 500 (^GSPC) are both up today. The Nasdaq (^IXIC) climbed enough to hit a new all-time intraday high. It all comes as investors' eyes turn from the Fed to Greece and the June 30 default deadline.

Here are some of the other stories Yahoo Finance is keeping an eye on today.

Fitbit IPO
The darling of Wall Street today is Fitbit (FIT). Shares are soaring on its first day of trading on the New York Stock Exchange. This comes after the maker of the popular wearable exercise measuring device had the best tech IPO this year last night, raising almost three quarters of a billion dollars.

Flat tax proposal
The flat tax is becoming a growing part of the 2016 Presidential campaign.  Republican hopeful Senator Rand Paul is presenting his plan today in a Wall Street Journal op-ed titled, "Blow up the tax code and start over."  Paul is calling for a tax rate of 14 and a half percent with deductions only for home mortgages and charitable contributions.

Facebook diversity
Facebook (FB) is reportedly turning to the NFL's playbook in an effort to diversify its workforce. Reports says the social media giant is trying out a hiring plan similar to the "Rooney Rule," named after Pittsburgh Steelers' chairman Dan Rooney.  That rule requires teams to interview minority candidates for coaching and general manager openings.

Overhead baggage size status quo
It appears your current airline carry-on bag is safe for now. After pushback by a trade group for this country's airlines, the International Air Transport Association is backing off its suggestion to reduce the allowable size of carry-on bags.  The plan would have made most current bags too big to fit the requirements.
