How do I choose the best investing app for me?
As you consider your options, there are a few things to keep in mind:

• Your investment budget: First, it’s important to understand your investment budget. Your budget should consider how much it will cost to invest as well as required account minimums. Realize, too, that passive investing is a long-term financial commitment. Avoid investing any amount of money that you think you’ll need in the near future.
• Available asset classes: Next, when evaluating the best investment apps, consider what types of assets you want to invest in. Different apps offer different investment options. For example, some make it easy to build a portfolio out of stocks, ETFs, and bonds. Others may offer options trading and cryptocurrencies.
  
• Account types: Figure out what types of accounts you want access to. For example, some investment platforms offer a wide variety of accounts, including individual retirement accounts (IRAs) and trust accounts, in addition to personal taxable investment accounts.
  
• Investment management fees and pricing: Many investment platforms charge fees, so it’s important to be aware of this when you’re deciding where to invest. Some platforms charge a monthly account fee based on the features you want to access. Others charge an annual fee based on the assets in the account.
  
• Security features: Don’t forget to look into security. You want to make sure your transactions are encrypted. Check to see whether the platform is registered with the Securities and Exchange Commission and see what clearinghouse it uses. For example, some platforms use Apex Clearing for their transactions, which means they have Securities Investor Protection Corporation (SIPC) insurance and are a member of the Financial Industry Regulatory Authority (FINRA).

How do I buy stock?
Buying stock with an investing app is typically quick and beginner-friendly. Here’s how it usually works:

1. Download and sign up: Choose an investing app, create an account, and complete identity verification (this is required by law).
2. Fund your account: Link your bank account and transfer funds. Many apps let you start with as little as $1.
3. Browse or search for a stock: Use the app’s search tool to find the company or ticker symbol you want to invest in.
4. Choose how much to invest: Decide if you want to buy full shares or fractional shares (many apps support both).
5. Place your order: Select “Buy,” enter your amount, and confirm. Most apps let you choose between market orders (buy now at the current price) or limit orders (buy only if the stock hits a specific price).
6. Track your investments: After purchase, you can monitor your stocks in the app’s portfolio section.

Most investing apps also offer educational tools to help guide you through the process if you’re new.

What are the safest types of investments?
Any investment comes with the risk of loss. Cash is generally considered one of the safest investments, but even with that, you have the chance of losing value through inflation. Bonds, especially U.S. Treasuries, are also considered among the safer investments because you’re supposed to get your principal at the end of the term, though there’s a chance of default.

The safest investments don’t generally offer the highest returns, though. In most cases, the lower the risk of loss, the lower your potential return. The right options for you will depend on your risk tolerance and personal finance preferences, as well as other factors.

Is my money safe with an investment platform?
While online investment platforms are not FDIC-insured like bank accounts, reputable platforms are typically regulated by financial authorities (like the SEC or FINRA) and offer SIPC protection by the Securities Investor Protection Corporation (SIPC), which insures securities up to $500,000 ($250,000 cash limit) in case the firm fails. However, SIPC does not protect against market fluctuations or poor investments.
