So, you have a stock portfolio, and you’re wondering: “How do I know if this is a good investment?”

The answer to that question lies in doing an analysis of your company’s stock.

Or are you looking at the broader picture of your entire portfolio? In that case, it’s time for a portfolio analysis.

So what is the difference between these two types of analyses? And how do I perform them myself? Well, that’s what we’ll try to answer here!

## Introduction to Stock Analysis

Stock analysis is the process of evaluating and forecasting the financial performance of a company. Stock analysts use various methods to come up with their valuations, including price-to-earnings ratios, price-to-book ratios, and so on.

They may also use statistical models based on past stock performance to predict future returns.

Stock analysts usually spend their time looking at large companies that have traded publicly for years – think Apple or Microsoft – but it’s possible for individual investors to perform stock analysis as well. In fact, many advisors recommend that you do your own research before investing in stocks because it makes you feel more confident about your choices and ensures that your investment portfolio is properly diversified across industries and sectors (more on this later).

## Introduction to Portfolio Analysis

Portfolio analysis is a way to determine how well a portfolio of investments is performing.

It can help investors decide if they should hold onto their investments or sell them, and it can help them determine if they are diversified enough.

Portfolio analysis is done by an investor, typically after the end of a quarter or year, who wants to see how their stocks performed over that period of time.

They look at all the different holdings in their portfolio and calculate their gains or losses for each one individually (or group).

Then they add up all those individual gains/losses to see what kind of net result there was for the whole bunch as a whole.

The investor might also do some research into how other similar portfolios performed during this same time frame; this will influence how they ultimately decide whether selling now would be best for their particular situation

## What Is the Difference Between a Stock Analysis and a Portfolio Analysis?

Stock analysis is the study of a single company’s financials and its performance.

A portfolio analysis, on the other hand, is an examination of multiple companies’ financials and their performance.

While both analyses take into account each company’s assets, liabilities and earnings per share (EPS), they differ in their focus:

- A stock analysis is more focused on the individual company’s performance while a portfolio analysis incorporates that information along with information about other companies as well.
- A portfolio analyst has to consider whether changes in one company’s balance sheet or income statement affect another company; this means that there are no hard-and-fast rules for making predictions about valuation or return on investment (ROI).

## How Do You Do a Stock Analysis?

Stock analysis is the process of evaluating the investment merits of a company.

A stock analysis should be conducted by any investor considering making an investment in a particular company.

A portfolio analysis is simply a stock analysis conducted on all the companies in your portfolio.

It’s important to note that while you may have several stocks or mutual funds, they are still separate entities and will have different characteristics, so it’s important to conduct an individual analysis for each one.

## How Do You Do a Portfolio Analysis?

To perform a portfolio analysis, you’ll need to first figure out the value of each individual stock in your portfolio.

To do this, you’ll use something called the weighted average cost basis method (WACCB) or the easy way method.

Here’s how it works: Go ahead and add up all of your stocks’ market values and divide that number by the total number of stocks (don’t forget to include the cash).

The result is what we call your cost basis—the average price at which you purchased each investment (but don’t let that fool you into thinking it’s just a simple average).

Then multiply that cost basis by 100% to get a new number called “percentage.” This percentage represents how much money was spent on each investment relative to the total value of all investments combined (100%).

For example, if one investment was $100 and another was $500 but together they totaled $1,000 in total investments:

⦁ Cost Basis + Profit = Percentage Value In Dollars

⦁ 0 + 100% = 100% Value In Dollars

## What Is the Purpose of an Investment Portfolio?

The purpose of a portfolio is to combine multiple investments so that you can take advantage of diversification.

When analyzing the risk and return of an investment portfolio, you are trying to determine if the overall investment strategy has been working for you or not.

You may also use this information to see if there are any changes that need to be made in order to improve your returns.

## What Are the Benefits of Doing a Stock Analysis or Portfolio Analysis?

A stock analysis or portfolio analysis can be a useful tool to help you determine the value of your investment and whether it is performing as expected.

It can also show you if your investment is worth the risk, and when it may be time to sell or hold on to your investment.

## What Is the Difference Between Equity and Debt Investments? (Stock vs Bond)

A stock investment is a share of ownership in a company, whereas a bond is essentially a loan to that same company.

As such, bonds have lower risk than stocks but offer lower returns as well.

On the other hand, stocks can be much more volatile but have the potential for higher returns over time due to their higher risk profile.

## How Do You Calculate Return on Investment (ROI)? (ROC=R/P)

Let’s take a look at how to calculate return on investment (ROI).

Return on Investment (ROI) is a measure of the profit that you make on an investment, expressed as a percentage. It can be calculated as:

\begin{equation} ROC = \frac{(R – C)}{C} \tag 1 \end{equation}

where:

• `R` – expected future returns from the stock analysis

• `C` – cost of investment (or price paid for shares)

## How Do You Calculate Risk and Return Ratios For Your Company’s Stocks?

First, let’s get the definitions out of the way. The risk of an investment is measured by its potential for loss.

Put another way, it’s how likely it is that you’ll lose your money on that investment.

If a stock drops in value and you sell it at a loss, then your return has been negative—you’ve lost money as a result of owning that stock.

The return on an investment is generally quantified as the increase or decrease in value (usually expressed as a percentage) over time.

For example, if you buy 100 shares of Company A at $10 per share and after six months they’re worth $12 per share, then you’ve made $200 on those shares; this means your total return would be 200%.

On paper that sounds great! But if instead, they’re only worth $8 each after six months (so now they’re worth 80% less than when you bought them), then suddenly making 80% doesn’t seem like such good news anymore…
