This month, we saw the Sunsea AIoT Technology Co., Ltd. (SZSE:002313) up an impressive 87%. But that is little comfort to those holding over the last half decade, sitting on a big loss. In fact, the share price has declined rather badly, down some 63% in that time. So we're hesitant to put much weight behind the short term increase. But it could be that the fall was overdone.

While the last five years has been tough for Sunsea AIoT Technology 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.

Sunsea AIoT Technology wasn't profitable in the last twelve months, it is unlikely we'll see a strong correlation between its share price and its earnings per share (EPS). Arguably revenue is our next best option. When a company doesn't make profits, we'd generally expect to see good revenue growth. As you can imagine, fast revenue growth, when maintained, often leads to fast profit growth.

In the last five years Sunsea AIoT Technology saw its revenue shrink by 6.7% per year. While far from catastrophic that is not good. The share price decline of 10% compound, over five years, is understandable given the company is losing money, and revenue is moving in the wrong direction. The chance of imminent investor enthusiasm for this stock seems slimmer than Louise Brooks. Ultimately, it may be worth watching - should revenue pick up, the share price might follow.

A Different Perspective

It's good to see that Sunsea AIoT Technology has rewarded shareholders with a total shareholder return of 54% in the last twelve months. Notably the five-year annualised TSR loss of 10% per year compares very unfavourably with the recent share price performance. The long term loss makes us cautious, but the short term TSR gain certainly hints at a brighter future. 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.
