How much money should I invest in stocks? If you’re investing through funds — have we mentioned this is our preference? — you can allocate a fairly large portion of your portfolio toward stock funds, especially if you have a long time horizon. A 30-year-old investing for retirement might have 80% of his or her portfolio in stock funds; the rest would be in bond funds. Individual stocks are another story. We’d recommend keeping these to 10% or less of your investment portfolio.
Overall commission costs can also be affected by new customer promotions. Brokers may give you a chunk of free trades based on your deposit amount. If your deposit gets you a substantial number of free trades, that can write off otherwise higher per-commission costs. Ally Invest offers small incentives for deposits as low as $500. Fidelity Investments, meanwhile, has a higher barrier for entry — it takes a $50,000 deposit, but then you'll get 300 free trades.
Unlike most online stock trading platforms, Robinhood doesn’t charge a commission fee every time you buy or sell stocks, ETFs, or options. If you’re a high-volume trader, or a beginner without much cash to spare, that makes Robinhood an attractive alternative to the $5 to $7 fees per trade offered by competitors. However, Robinhood does rake in “payment for order flow” by rounding regulatory fees up to the nearest penny and pocketing the difference. “That means if you buy a stock for $100.00, Robinhood earns 2.6 cents from the market maker,” says co-founder and co-CEO Vlad Tenev, whereas “other brokerages earn rebates and charge you a per-trade commission fee.”
Thinkorswim is a particular standout in options trading, with options-trading tabs (just click “spread” if you want a spread and “single order” if you want one leg), plus links that explain the strategies on the order page. Its Strategy Roller feature lets investors create custom covered calls and then roll those positions from expiration to expiration.

There are risks associated with investing in a public offering, including unproven management, and established companies that may have substantial debt. As such, they may not be appropriate for every investor. Customers should read the offering prospectus carefully, and make their own determination of whether an investment in the offering is consistent with their investment objectives, financial situation, and risk tolerance.
