Keep good records for the IRS. If you’re not using an account that enjoys tax-favored status — such as a 401(k) or other workplace accounts, or a Roth or traditional IRA — taxes on investment gains and losses can get complicated. The IRS applies different rules and tax rates, and requires the filing of different forms for different types of traders. (Here’s an overview of the IRS rules for stock traders.) Another benefit of keeping good records is that loser investments can be used to offset the taxes paid on income through a neat strategy called tax-loss harvesting.
When you've been approved for margin stock trading, you're also eligible to short stock. Almost every successful stock trader has shorted stock at one time or another. When you short stock, you make money when the company's shares fall—or, even better yet, when they crash. The problem is that you can expose yourself to unlimited liability when you do this.
“I know stocks can be a great investment, but I’d like someone to manage the process for me.” You may be a good candidate for a robo-advisor, a service that offers low-cost investment management. Virtually all of the major brokerage firms offer these services, which invest your money for you based on your specific goals. See our top picks for robo-advisors.
