We're definitely into long term investing, but some companies are simply bad investments over any time frame. We really hate to see fellow investors lose their hard-earned money. Imagine if you held Sunlands Technology Group (NYSE:STG) for half a decade as the share price tanked 78%. Even worse, it's down 19% in about a month, which isn't fun at all. Importantly, this could be a market reaction to the recently released financial results. You can check out the latest numbers in our company report.

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.

View our latest analysis for Sunlands Technology Group

While markets are a powerful pricing mechanism, share prices reflect investor sentiment, not just underlying business performance. One imperfect but simple way to consider how the market perception of a company has shifted is to compare the change in the earnings per share (EPS) with the share price movement.

Sunlands Technology Group became profitable within the last five years. Most would consider that to be a good thing, so it's counter-intuitive to see the share price declining. Other metrics might give us a better handle on how its value is changing over time.

Revenue is actually up 1.6% over the time period. A more detailed examination of the revenue and earnings may or may not explain why the share price languishes; there could be an opportunity.

What About The Total Shareholder Return (TSR)?

We'd be remiss not to mention the difference between Sunlands Technology Group's total shareholder return (TSR) and its share price return. The TSR attempts to capture the value of dividends (as if they were reinvested) as well as any spin-offs or discounted capital raisings offered to shareholders. Sunlands Technology Group hasn't been paying dividends, but its TSR of -75% exceeds its share price return of -78%, implying it has either spun-off a business, or raised capital at a discount; thereby providing additional value to shareholders.

A Different Perspective

Sunlands Technology Group's TSR for the year was broadly in line with the market average, at 25%. The silver lining is that the share price is up in the short term, which flies in the face of the annualised loss of 12% over the last five years. We're pretty skeptical of turnaround stories, but it's good to see the recent share price recovery.
