Revenue Growth
Examining a company’s long-term performance can provide clues about its quality. Any business can experience short-term success, but top-performing ones enjoy sustained growth for years. Over the last five years, Interactive Brokers grew its revenue at an exceptional 21.6% compounded annual growth rate. Its growth surpassed the average financials company and shows its offerings resonate with customers, a great starting point for our analysis.
We at StockStory place the most emphasis on long-term growth, but within financials, a half-decade historical view may miss recent interest rate changes, market returns, and industry trends. Interactive Brokers’s annualized revenue growth of 18.6% over the last two years is below its five-year trend, but we still think the results suggest healthy demand. 
Note: Quarters not shown were determined to be outliers, impacted by outsized investment gains/losses that are not indicative of the recurring fundamentals of the business.
This quarter, Interactive Brokers’s year-on-year revenue growth was 19.6%, and its $1.67 billion of revenue was in line with Wall Street’s estimates.
