# How to Pick Good Stocks

Investors spend a lot of time debating how to choose stocks. Many follow
advice from brokers, while others act on hot tips they read in magazines or
online. When [the market fluctuates dramatically every day](https://trendshare.org/how-to-invest/what-happened-in-the-stock-market-today), it can feel like picking a good stock is
a matter of chance. You do not have to treat it that way.
Finding good stocks is easier when you remember two simple ideas about what
makes a business worth owning. The rest is systematic research and patience.
## Good Companies Earn Money Reliably
[Successful companies generate cash](https://trendshare.org/how-to-invest/earnings-matter-most) year
after year. You can spend time chasing buzz, but that rarely helps you find the
best investments. Publicity does not pay the bills. Focus instead on businesses
that have stable revenue, durable customers, and sensible cost structures.
When you limit your search to companies that are worth owning as businesses
you lower risk. Good stocks are simply shares in good businesses, so start
there and work outward.
## Great Investors Think Like Owners
Think about a business you would be happy owning. You do not need an
accounting degree. You need to understand how the business makes money and why
it will keep making money. A practical owner asks a few simple questions: what
does the company sell, who are the customers, and who are the competitors?
Start with what you know. Your hobbies, the products you buy, and the
industries your friends work in are fertile places to find ideas. If you can
describe how the business earns revenue and how it could grow, you are already
well on your way.
*You probably already know this about several companies.*
Whether you're passionate about airplanes or model cars or fashion, you can
probably come up with a list of a dozen companies worth investigating. Find out
if they're publicly traded. Get their names and [market symbols](https://trendshare.org/how-to-invest/what-do-stock-market-symbols-mean).
## How to Choose a Stock to Invest In
There is no single stock everyone should own. What matters is finding the
right stock for you. A right stock is one that belongs to a company that earns
money reliably and that you can value sensibly. Narrow your list to companies
you understand, then decide if the current price gives you a margin of safety.
Great stock picks are simply good businesses available at good prices. That
combination is not common, but it is discoverable if you do a bit of homework
and wait for opportunity.
What makes a hidden gem? That's the subject of [Trendshare's investing articles](/how-to-invest/). Trendshare's [value investing](https://trendshare.org/how-to-invest/what-is-value-investing) strategy looks at the past
several years of history for every business to analyze the basic financial
numbers. The result is an analysis of what the company has done and it produces
a fair price you shouldn't pay more than for a share of the stock right now.
(This technique has served people like Warren Buffett and [Benjamin Graham](https://trendshare.org/how-to-invest/benjamin-graham-value-investor) very well.)
The rest is up to you.
## How to Pick Stocks with Trendshare
Make a short watchlist of companies you find interesting. Run them through
the [Trendshare stock analysis](/stocks) and shrink the list to a
few candidates worth deeper study. For each candidate, ask yourself: do I know
how this company makes money and how that could improve over time?
Use our [investing guide](/how-to-invest/) to learn the steps of
setting up online buying, making a first investment, and assembling the pieces
of a convincing investment case. The work is simple: study, value, and wait.
There is no secret formula that does all the work for you. Good stocks are
out there. Be prepared, do the research, and be patient when the right price
appears.
## How to find undervalued stocks using this checklist
Finding undervalued stocks does not mean chasing the lowest price. It's
finding quality businesses trading below their intrinsic value. Start with the
checklist here focus on companies where the numbers tell a consistent story.
Look for businesses with stable or growing revenue, positive free cash flow,
and reasonable debt levels. Check if the P/E ratio is lower than the industry
average or the company's historical range. Compare return on invested capital
across several years to see if the business earns strong returns
consistently.
Most importantly, calculate a rough intrinsic value using conservative growth
assumptions. If the current stock price gives you a 20 to 30 percent margin of
safety below your estimate, the stock may be undervalued—and worth buying!
Use the Trendshare stock analysis to see our calculated fair value for any
publicly traded company.
Remember that undervalued does not always mean cheap in absolute dollar
terms. A stock trading at 100 dollars per share can be undervalued if the
business is worth 150 dollars per share. The goal is to *buy assets for less than
they are worth*.
## Beginner stock checklist - 5 steps to research a stock
### Step 1 - Make a short watchlist
Write down five to twenty companies you know a little about. Pick names from
your hobbies, the products you buy, or industries you understand. This is not
about popularity, it is about familiarity and starting points for deeper work.
### Step 2 - Understand the business
Describe how the company earns revenue. Who pays it, what do they buy, and
what makes customers stay? If you can explain the basic economics in a few
sentences, you have a framework for judging the company.
### Step 3 - Check core financial ratios
Look at valuation and performance ratios over several years. Key ratios to
review are price earnings, return on invested capital, and free cash flow. See
the examples below for how to read trend lines and what to drill into next.
### Step 4 - Estimate intrinsic value
Use conservative assumptions to estimate what the business is worth. If the
current price gives you a reasonable margin of safety, it is worth further
consideration. If not, file it for later and move on.
### Step 5 - Decide position size and buy plan
Plan how much to buy, when, and whether you will use dollar cost averaging or
invest a lump sum. Set rules for trade costs and rebalancing before you commit.
## Key ratios to check
### Price earnings (P/E)
Price earnings gives a shorthand for valuation. Look at the ratio across a
cycle and not just the current number. A single low P/E may hide weak earnings
or one time gains; a simple trend will tell you more than a single point.
### Return on invested capital (ROIC)
ROIC measures how well a company converts capital into profit. Higher ROIC
over time suggests durable competitive advantages. Compare ROIC to peers in the
same industry for context.
### Free cash flow (FCF)
Free cash flow is the cash left after investment. Positive and growing FCF is
a strong indicator that a company can pay dividends, reduce debt, and buy
back shares. Trendshare shows normalized FCF to help remove one time items.
See an example analysis on [Apple (AAPL)](/stocks/AAPL) or run a
stock through our [Trendshare stock analysis](/stocks).

[See Apple (AAPL) example →](/stocks/AAPL)
#### FCF
Free Cash Flow
$12.4B
+8% YoY
5-Year Trend
Growing free cash flow shows the business generates real cash for dividends and growth.
**How to calculate:** Operating Cash Flow - Capital Expenditures
**What to look for:** Positive and growing. Compare to net income to check quality of earnings.

## Frequently asked questions
### What data should I trust when researching a stock?
Prioritize audited company filings and well established metrics such as
revenue and operating cash flow. Trendshare uses normalized historical
numbers to remove one time items so you can compare underlying performance.
### How many stocks should a beginner hold?
Beginners often hold ten to twenty well researched stocks. If you prefer
fewer decisions and broader diversification, consider a low cost index fund.
Your ideal number depends on time, diversification needs, and how much research you
can do on each company.
### What ratios matter most?
Look at P/E for valuation, ROIC for returns on capital, and FCF for cash
generation. Always focus on trends rather than a single period number.
### Should I use dollar cost averaging or invest a lump sum?
Dollar cost averaging reduces timing risk, while lump sum investing can
outperform over long periods in rising markets. Use a calculator to compare
outcomes and account for trade fees.
## Try the DCA vs Lump Sum Calculator
Compare dollar cost averaging against lump sum investing with your own numbers.
Adjust the amount, time period, fees, and expected returns to see which strategy
works better for your situation.
