Many small-cap stocks have limited Wall Street coverage, giving savvy investors the chance to act before everyone else catches on. But the flip side is that these businesses have increased downside risk because they lack the scale and staying power of their larger competitors.
These trade-offs can cause headaches for even the most seasoned professionals, which is why we started StockStory - to help you separate the good companies from the bad. Keeping that in mind, here are three small-cap stocks to swipe left on and some alternatives you should look into instead.

Why Do We Think ONTF Will Underperform?
- Offerings couldn’t generate interest over the last year as its billings have averaged 8.1% declines
- Sales are expected to decline once again over the next 12 months as it continues working through a challenging demand environment
