Why is Earnings Season So Important?

By Derek Lewis | October 15, 2025, 5:03 PM

Imagine that, once every few months, you must release information detailing your current financial standing. The public can see where you’ve spent money, made money, or even how much you’ve saved.

Sounds intimidating, right?

That’s just a different way of describing what earnings season is.

The period is undoubtedly hectic for market participants, with companies finally revealing what’s transpired behind closed doors.

And on top of being hectic, it’s impossible to understate the importance of the period. For those wondering why it’s so critical, let’s look at a few reasons that help explain its significance.

Critical Business Updates

Earnings reports provide market participants with a plethora of information, including revenues, expenses, and profits, just to provide a few simple examples.

Take, for example, Palantir PLTR. Palantir has communicated that it’s been enjoying healthy demand thanks to the AI frenzy, reflected by consistently strong results. 

Palantir is expected to see 60% EPS growth on 45% higher sales in its current fiscal year.

Share Price Impact

A company’s quarterly earnings report commonly impacts its stock price, a theme that market participants have undoubtedly noticed. Typically, we’ll see bullish share movement post-earnings from companies that surprise positively or raise their guidance, reflecting healthy underlying business.

PepsiCo PEP saw its shares see post-earnings positivity recently, beating both top and bottom line expectations. It’s worth noting that implementing a stop-loss at a comfortable threshold will help limit spooky post-earnings price swings, preserving precious capital.

Highlights Current Trends

Earnings season can also provide a big-picture view of overall trends within the economy or industries. For a simple example, if many retail companies fall short of expectations, it could be a sign of a slowing consumer or economy, which has knock-on effects across the market.

Conversely, if many retail companies report stronger-than-expected earnings, it may signal that the economy is moving along just fine, underpinned by a healthy consumer.

Bottom Line

While earnings season is undeniably hectic for everyone involved, that’s just the nature of the period.

It’s important for investors to understand why it matters for many reasons, including providing investors with an updated financial standing, the volatile post-earnings share swings, and the overall picture it provides on market and broader trends.
