Boku's (LON:BOKU) 16% CAGR outpaced the company's earnings growth over the same three-year period

By buying an index fund, investors can approximate the average market return. But many of us dare to dream of bigger returns, and build a portfolio ourselves. Just take a look at Boku, Inc. (LON:BOKU), which is up 55%, over three years, soundly beating the market return of 25% (not including dividends). However, more recent returns haven't been as impressive as that, with the stock returning just 22% in the last year.

Since the stock has added UK£37m to its market cap in the past week alone, let's see if underlying performance has been driving long-term returns.

While markets are a powerful pricing mechanism, share prices reflect investor sentiment, not just underlying business performance. One way to examine how market sentiment has changed over time is to look at the interaction between a company's share price and its earnings per share (EPS).

During three years of share price growth, Boku achieved compound earnings per share growth of 6.0% per year. In comparison, the 16% per year gain in the share price outpaces the EPS growth. So it's fair to assume the market has a higher opinion of the business than it did three years ago. It is quite common to see investors become enamoured with a business, after a few years of solid progress. This favorable sentiment is reflected in its (fairly optimistic) P/E ratio of 66.48.

It's probably worth noting that the CEO is paid less than the median at similar sized companies. But while CEO remuneration is always worth checking, the really important question is whether the company can grow earnings going forward.

A Different Perspective

Boku provided a TSR of 22% over the last twelve months. But that return falls short of the market. On the bright side, that's still a gain, and it's actually better than the average return of 7% over half a decade It is possible that returns will improve along with the business fundamentals. I find it very interesting to look at share price over the long term as a proxy for business performance. But to truly gain insight, we need to consider other information, too.
