How to Analyze Stocks Before Deciding on a Trade

Astron Team · 09/24/2026 · 6 min read

Choosing a stock to trade just because it's trending on social media is a well-known recipe for rushed decisions. A more structured analysis, combining the company's fundamentals with the price behavior on the chart, reduces reliance on luck when deciding where to enter.

Two different lenses, one shared goal

There are, basically, two complementary approaches to analyzing a stock:

• Fundamental analysis: assesses the financial health and growth potential of the company behind the stock.
• Technical analysis: assesses the price behavior on the chart, looking for trend, support, resistance, and volume patterns.

Using both together usually gives a more complete picture than using just one: fundamental analysis helps you understand whether the company is solid; technical analysis helps you understand whether the price timing favors an entry.

What to look at in fundamental analysis

Without needing to become a professional financial analyst, a few basic indicators already help a lot:

• Revenue and profit: is the company growing consistently over the past few quarters, or are the numbers stagnant or falling?
• Profit margin: how much of the revenue actually turns into profit, after deducting costs and expenses.
• Debt level: a heavily indebted company has less flexibility to weather difficult periods.
• Comparison with the sector: do the company's numbers make sense when compared to direct competitors in the same sector?

This data is usually available in the quarterly financial reports publicly disclosed by publicly listed companies.

What to look at in technical analysis

After understanding the fundamentals, technical analysis helps assess timing:

• Trend: has the price been rising, falling, or moving sideways over the past few months?
• Support and resistance: are there price levels where buyers or sellers have historically reacted strongly?
• Volume: do recent moves come with growing volume, suggesting real participation, or with weak volume, which can indicate a less reliable move?

Combining both analyses in an example

Imagine a company reporting 15% annual revenue growth over the last three quarters, with a stable profit margin and controlled debt. From a fundamental standpoint, that's a positive sign.

Now look at that same stock's chart: if the price is in a clear uptrend, respecting an ascending support and with growing volume on up days, the technical picture reinforces what the fundamentals already suggested. If, on the other hand, the price is trending down despite good fundamentals, that can indicate the market is already pricing in some risk that hasn't clearly shown up in the disclosed numbers yet, and it's worth investigating before acting on the fundamental side alone.

Common mistakes at this stage

A few slip-ups show up often among people learning to analyze stocks:

• Basing the entire decision on a single news item or third-party recommendation, without checking the numbers themselves.
• Ignoring the sector context: a drop in profit can be a company-specific problem or something affecting the whole sector.
• Confusing a good company with a cheap stock: the fundamentals can be excellent, but if the price already prices in all that optimism, the potential for further upside may be limited.

How often to review the analysis

Fundamental and technical analysis aren't one-time exercises. A company's financial numbers change every quarter, as new results are released, and the chart's behavior changes every day. Periodically reviewing both fronts, especially before renewing or expanding a position, helps confirm whether the original reasons behind that trade are still valid.

This is especially important when relevant news about the company or sector comes up: it's worth going back to the numbers and the chart to reassess the scenario, instead of keeping a position simply out of inertia.

Before deciding on any trade

No combination of fundamental and technical analysis guarantees a correct call: both help organize the decision with more rigor, reducing reliance on guesswork, but the market remains subject to unpredictable events. Price-tracking tools, like the ones available on Astron, help with the technical part of this analysis, but interpreting the fundamentals requires your own research into the company's reports.

Investing in or trading stocks involves risk of capital loss, even when the analysis was done carefully. Defining in advance how much you're willing to risk on each trade remains just as important as the quality of the analysis behind it.
