If you're curious about entering the stock world but have no idea where to begin, the easiest and best way to jump into the deep end is by downloading the app Robinhood. The tech-driven brokerage is completely free with no trading commissions or fees, plus the app couldn't be easier to use. Apple had it on their "Best Apps Of 2015" list for a reason, it's truly outstanding.
Here's a great video which breaks down the ins-and-outs super quickly.
For anybody either intimated by this world or unsure about old school firms with hidden fees and general shadiness, this is definitely the ticket. Happy trading.
