What is the 95% value at risk?
It is defined as the maximum dollar amount expected to be lost over a given time horizon, at a pre-defined confidence level. For example, if the 95% one-month VAR is $1 million, there is 95% confidence that over the next month the portfolio will not lose more than $1 million.
What does 5% VaR mean?
Value At RiskThe VaR calculates the potential loss of an investment with a given time frame and confidence level. For example, if a security has a 5% Daily VaR (All) of 4%: There is 95% confidence that the security will not have a larger loss than 4% in one day.
What does 99% VaR mean?
From standard normal tables, we know that the 95% one-tailed VAR corresponds to 1.645 times the standard deviation; the 99% VAR corresponds to 2.326 times sigma; and so on.

How do you calculate market risk for a portfolio?
The market risk premium can be calculated by subtracting the risk-free rate from the expected equity market return, providing a quantitative measure of the extra return demanded by market participants for the increased risk. Once calculated, the equity risk premium can be used in important calculations such as CAPM.
Why are stocks volatile?
The main problem with volatility, however, is that it does not care about the direction of an investment's movement: stock can be volatile because it suddenly jumps higher. Of course, investors aren't distressed by gains.
What are the components of a VAR statistic?
Now let's get specific. A VAR statistic has three components: a time period, a confidence level and a loss amount (or loss percentage). Keep these three parts in mind as we give some examples of variations of the question that VAR answers: 1 What is the most I can—with a 95% or 99% level of confidence —expect to lose in dollars over the next month? 2 What is the maximum percentage I can—with 95% or 99% confidence—expect to lose over the next year?
What is a VAR?
Value at Risk (VAR) calculates the maximum loss expected (or worst case scenario) on an investment, over a given time period and given a specified degree of confidence. We looked at three methods commonly used to calculate VAR. But keep in mind that two of our methods calculated a daily VAR and the third method calculated monthly VAR. In Part 2 of this series, we show you how to compare these different time horizons .
What is the problem with using beta as a measure of a stock's risk?
Of course, the problem with using beta as a measure of a stock's risk is this: Beta measures how much a given stock's price deviates from "normal" stock price movements. A high-beta stock could be one that falls steeply when the stock market merely stumbles, a stock that soars when the market just plods along, or both.

Can you let $500 go to zero?
Unless you're an inexperienced stock investor, you would never let that $500 go all the way to zero. Your actual risk isn't the entire $500. Every good investor has a stop-loss or a price on the downside that limits their risk. If you set a $29 sell limit price as the upside, maybe you set $20 as the maximum downside.
Is it better to invest 500 to gain millions?
Risking $500 to gain millions is a much better investment than investing in the stock market from a risk/reward perspective, but a much worse choice in terms of probability. In the course of holding a stock, the upside number is likely to change as you continue analyzing new information.

Is there a protocol for determining asset risk?
There is no standard protocol for the statistics used to determine asset, portfolio or firm-wide risk. For example, statistics pulled arbitrarily from a period of low volatility may understate the potential for risk events to occur and the magnitude of those events.
How to value a stock?
The most common way to value a stock is to compute the company's price-to-earnings (P/E) ratio . The P/E ratio equals the company's stock price divided by its most recently reported earnings per share (EPS). A low P/E ratio implies that an investor buying the stock is receiving an attractive amount of value.
Why do investors assign value to stocks?

What is the last valuation model?
The last model is sort of a catch-all model that can be used if you are unable to value the company using any of the other models, or if you simply don't want to spend the time crunching the numbers . This model doesn't attempt to find an intrinsic value for the stock like the previous two valuation models. Instead, it compares the stock's price multiples to a benchmark to determine if the stock is relatively undervalued or overvalued. The rationale for this is based on the Law of One Price, which states that two similar assets should sell for similar prices. The intuitive nature of this model is one of the reasons it is so popular.
What is absolute valuation?
Absolute valuation models attempt to find the intrinsic or "true" value of an investment based only on fundamentals. Looking at fundamentals simply means you would only focus on such things as dividends, cash flow, and the growth rate for a single company—and not worry about any other companies. Valuation models that fall into this category include the dividend discount model, discounted cash flow model, residual income model, and asset-based model.
Is relative valuation easier to calculate than absolute valuation?
Typically, the relative valuation model is a lot easier and quicker to calculate than the absolute valuation model, which is why many investors and analysts begin their analysis with this model.

Why do stocks have high P/E?
The reason stocks tend to have high P/E ratios is that investors try to predict which stocks will enjoy progressively larger earnings. An investor may buy a stock with a P/E ratio of 30 if they think it will double its earnings every year (shortening the payoff period significantly).
Why are dividend stocks attractive?
It's always nice to have a back-up when a stock's growth falters. This is why dividend-paying stocks are attractive to many investors—even when prices drop, you get a paycheck. The dividend yield shows how much of a payday you're getting for your money. By dividing the stock's annual dividend by the stock's price, you get a percentage. You can think of that percentage as the interest on your money, with the additional chance at growth through the appreciation of the stock.
Why do investors use the PEG ratio?
Because the P/E ratio isn't enough in and of itself, many investors use the price to earnings growth (PEG) ratio. Instead of merely looking at the price and earnings, the PEG ratio incorporates the historical growth rate of the company's earnings. This ratio also tells you how company A's stock stacks up against company B's stock.
Why is a low P/B ratio good?
In either case, a low P/B ratio can protect you— but only if it's accurate. This means an investor has to look deeper into the actual assets making up the ratio.

Can a stock go up without earnings?
A stock can go up in value without significant earnings increases, but the P/E ratio is what decides if it can stay up. Without earnings to back up the price, a stock will eventually fall back down. An important point to note is that one should only compare P/E ratios among companies in similar industries and markets.

The Idea Behind var
Methods of Calculating var
Historical Method
- The historical method simply re-organizes actual historical returns, putting them in order from worst to best. It then assumes that history will repeat itself, from a risk perspective. As a historical example, let's look at the Nasdaq 100 ETF, which trades under the symbol QQQ (sometimes called the "cubes"), and which started trading in March of 1999.3 If we calculate each daily return, we p…
The Variance-Covariance Method
- This method assumes that stock returns are normally distributed. In other words, it requires that we estimate only two factors—an expected (or average) return and a standard deviation—which allow us to plot a normal distribution curve. Here we plot the normal curve against the same actual returndata: The idea behind the variance-covariance is similar to the ideas behind the hist…
Monte Carlo Simulation
- The third method involves developing a model for future stock price returns and running multiple hypothetical trials through the model. A Monte Carlo simulationrefers to any method that randomly generates trials, but by itself does not tell us anything about the underlying methodology. For most users, a Monte Carlo simulation amounts to a "black box" generator of ra…

Special Considerations
How to Calculate Risk/Reward
- Remember, to calculate risk/reward, you divide your net profit (the reward) by the price of your maximum risk. Using the XYZ example above, if your stock went up to $29 per share, you would make $4 for each of your 20 shares for a total of $80. You paid $500 for it, so you would divide 80 by 500 which gives you 0.16. That means that your risk/rewar...
