TDSE Inc.'s (TSE:7046) 29% Share Price Surge Not Quite Adding Up

The TDSE Inc. (TSE:7046) share price has done very well over the last month, posting an excellent gain of 29%. The bad news is that even after the stocks recovery in the last 30 days, shareholders are still underwater by about 4.8% over the last year.

After such a large jump in price, TDSE's price-to-earnings (or "P/E") ratio of 27x might make it look like a strong sell right now compared to the market in Japan, where around half of the companies have P/E ratios below 13x and even P/E's below 9x are quite common. Although, it's not wise to just take the P/E at face value as there may be an explanation why it's so lofty.

This technology could replace computers: discover the 20 stocks are working to make quantum computing a reality.

For instance, TDSE's receding earnings in recent times would have to be some food for thought. One possibility is that the P/E is high because investors think the company will still do enough to outperform the broader market in the near future. You'd really hope so, otherwise you're paying a pretty hefty price for no particular reason.

Is There Enough Growth For TDSE?

The only time you'd be truly comfortable seeing a P/E as steep as TDSE's is when the company's growth is on track to outshine the market decidedly.

Taking a look back first, the company's earnings per share growth last year wasn't something to get excited about as it posted a disappointing decline of 32%. This means it has also seen a slide in earnings over the longer-term as EPS is down 9.5% in total over the last three years. So unfortunately, we have to acknowledge that the company has not done a great job of growing earnings over that time.

Weighing that medium-term earnings trajectory against the broader market's one-year forecast for expansion of 7.8% shows it's an unpleasant look.

With this information, we find it concerning that TDSE is trading at a P/E higher than the market. Apparently many investors in the company are way more bullish than recent times would indicate and aren't willing to let go of their stock at any price. Only the boldest would assume these prices are sustainable as a continuation of recent earnings trends is likely to weigh heavily on the share price eventually.

The Bottom Line On TDSE's P/E

The strong share price surge has got TDSE's P/E rushing to great heights as well. Using the price-to-earnings ratio alone to determine if you should sell your stock isn't sensible, however it can be a practical guide to the company's future prospects.

Our examination of TDSE revealed its shrinking earnings over the medium-term aren't impacting its high P/E anywhere near as much as we would have predicted, given the market is set to grow. When we see earnings heading backwards and underperforming the market forecasts, we suspect the share price is at risk of declining, sending the high P/E lower. If recent medium-term earnings trends continue, it will place shareholders' investments at significant risk and potential investors in danger of paying an excessive premium.
