Tax liabilities..........until child is an adult, parent is responsible. Many forms to be signed by the responsible adult.
ETrade and TDAmeritrade are good.....but adult has to be owner of account. As little as $500 will open an account. Child COULD practice trading "on paper"........play trading under your name.
Looks easy, but, the big boys have the insider trades going, and can buy 24/7. Small traders are limited to one hour before market and a few hours after market.
Small traders cannot "bounce in and out" like we could until about 12 years ago. Used to "bounce in n out" all day long. NOW.....only 3 "round trips"(in and out of same stock) are allowed in a 5 business day period. More than that, they will lock the account for 90 days.
UNLESS, you have $25,000 balance at all times. Then you can "round trip" ALL DAY LONG.
Currently the marijuana stocks are expected to be the "Next Big Thing"........they were from late December, last three weeks they have dropped. Possibly because of uncertainty of what the NEW Attorney General Sessions will do. He is on record as anti-marijuana. Several big name professional politicians STILL say they believe MJ is an addictive gateway drug. Not the case, but that has not stopped the putrid 50+ year persecution of MJ users started by disgraced richard nixon. His "War of Drugs" continues to destroy our beautiful America.
Write me privately, I can give you a list of top/active MJ stocks..........most are penny stocks. Several are big time stocks. Did you know Miracle Grow is investing 500 million in the MJ market?
They have bought several companies and buying more. Most penny stocks will die on the vine, maybe 6 will flourish and grow into the next Microsoft. Staying informed and choosing wisely is essential.
