If you're a stock investor, you've heard of blue chips such as Apple, Facebook and Visa. But what about Okta? Or Sunrun? Does Twilio ring a bell?
Chances are you're drawing a blank.
The reason: These are small stocks that are "coming of age, undiscovered, under the radar and less followed by Wall Street," says Amy Zhang, manager of the Alger Small Cap Focus Fund.
Their relative obscurity, however, hasn't kept them from becoming some of Wall Street's highest-flying stocks this year. All of them have doubled in value and are among a list of companies in the small-company Russell 2000 stock index that have gained more than 100%, according to Bloomberg.
Nearly halfway through 2018, the overall index is up 9.6 percent, much more than the 4.2 percent gain of the large-company Standard & Poor's 500 stock index.
It's "small caps' turn," Edward Campbell, a senior portfolio manager at financial firm QMA in Newark, N.J., wrote in a report, referring to the lower capitalization of these small companies.
Small stocks are benefiting from shifts in policy and the geopolitical mood. Their tax bills are now lower, which has boosted earnings. Another positive is that they generate most of their sales in the U.S., which has a strong economy and also insulates them from current international trade conflicts and tariffs.
Along with the current strengths, small-cap stocks also have the allure of raw potential. Investors who buy shares of small firms "are betting on a much bigger company" in the years ahead, says JP Gravitt, CEO and chief market strategist at Market Realist, an independent market research firm.
But before diving headfirst into the small-cap market, investors must be aware of the risks, Gravitt warns. For every big winner in the Russell 2000, there are also big losers. Currently, there are roughly three dozen stocks in the index that are down more than 50 percent, according to Bloomberg.
Small companies' fortunes often depend on a handful of key customers, so losing a big client can damage the business. There's always a chance a new product won't pan out, or a drug with promise won't pass muster with regulators, or some management misstep causes irreparable harm. In some cases, these companies are spending so much to acquire new customers and book more sales that they don't even earn a profit.
