3 Top Small-Cap Stocks to Buy in October

Even though Halloween is coming, don't let all small-cap stocks scare you. While it's generally true that smaller businesses present higher risks to investors than larger companies do, they may also offer the potential for outsized returns. Therefore, it may be worth it to take the long-term view on a promising small-cap stock in hopes that it grows its market cap steadily over time.

With that in mind, if you're looking for some top small-cap stocks to buy in October before 2017 comes to a close, then consider enzyme leader Codexis (NASDAQ: CDXS), genetic-testing leader Invitae (NYSE: NVTA), and the world's second-largest ethanol producer, Green Plains (NASDAQ: GPRE).
