The best diamond stocks depend on your portfolio and investment goals — while volatility can be ideal for day traders, long-term investors will want to look to stocks with steadier gains over time.
You'll also want to consider which stocks are easy to buy. Many diamond stocks are located on non-US exchanges, which means you'll need a brokerage account that offers access to international stocks. Different brokerages offer access to different exchanges, so if you're interested in a specific non-US stock, you'll want to check if it's available through your brokerage account.
