It is a pleasure to report that the Luminar Technologies, Inc. (NASDAQ:LAZR) is up 47% in the last quarter. But the last three years have seen a terrible decline. To wit, the share price sky-dived 89% in that time. So it sure is nice to see a bit of an improvement. But the more important question is whether the underlying business can justify a higher price still. While a drop like that is definitely a body blow, money isn't as important as health and happiness.

While the last three years has been tough for Luminar Technologies shareholders, this past week has shown signs of promise. So let's look at the longer term fundamentals and see if they've been the driver of the negative returns.

Luminar Technologies isn't currently profitable, so most analysts would look to revenue growth to get an idea of how fast the underlying business is growing. Generally speaking, companies without profits are expected to grow revenue every year, and at a good clip. That's because it's hard to be confident a company will be sustainable if revenue growth is negligible, and it never makes a profit.

In the last three years, Luminar Technologies saw its revenue grow by 45% per year, compound. That's well above most other pre-profit companies. So why has the share priced crashed 24% per year, in the same time? You'd want to take a close look at the balance sheet, as well as the losses. Sometimes fast revenue growth doesn't lead to profits. Unless the balance sheet is strong, the company might have to raise capital.

We're pleased to report that the CEO is remunerated more modestly than most CEOs at similarly capitalized companies. It's always worth keeping an eye on CEO pay, but a more important question is whether the company will grow earnings throughout the years.

A Different Perspective

While the broader market gained around 24% in the last year, Luminar Technologies shareholders lost 73%. 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. Unfortunately, last year's performance may indicate unresolved challenges, given that it was worse than the annualised loss of 13% over the last half decade. We realise that Baron Rothschild has said investors should "buy when there is blood on the streets", but we caution that investors should first be sure they are buying a high quality business. 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.
