For many investors, the main point of stock picking is to generate higher returns than the overall market. But in any portfolio, there are likely to be some stocks that fall short of that benchmark. Unfortunately, that's been the case for longer term Liberty Broadband Corporation (NASDAQ:LBRD.K) shareholders, since the share price is down 50% in the last three years, falling well short of the market return of around 28%. Unfortunately the share price momentum is still quite negative, with prices down 12% in thirty days.

With that in mind, it's worth seeing if the company's underlying fundamentals have been the driver of long term performance, or if there are some discrepancies.

While the efficient markets hypothesis continues to be taught by some, it has been proven that markets are over-reactive dynamic systems, and investors are not always rational. One flawed but reasonable way to assess how sentiment around a company has changed is to compare the earnings per share (EPS) with the share price.

Although the share price is down over three years, Liberty Broadband actually managed to grow EPS by 19% per year in that time. Given the share price reaction, one might suspect that EPS is not a good guide to the business performance during the period (perhaps due to a one-off loss or gain). Alternatively, growth expectations may have been unreasonable in the past.

Since the change in EPS doesn't seem to correlate with the change in share price, it's worth taking a look at other metrics.

Revenue is actually up 3.1% over the three years, so the share price drop doesn't seem to hinge on revenue, either. It's probably worth investigating Liberty Broadband further; while we may be missing something on this analysis, there might also be an opportunity.

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. So it makes a lot of sense to check out what analysts think Liberty Broadband will earn in the future (free profit forecasts).

A Different Perspective

Liberty Broadband shareholders are down 3.2% for the year, but the market itself is up 26%. Even the share prices of good stocks drop sometimes, but we want to see improvements in the fundamental metrics of a business, before getting too interested. However, the loss over the last year isn't as bad as the 7% per annum loss investors have suffered over the last half decade. We would want clear information suggesting the company will grow, before taking the view that the share price will stabilize. 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.
