Similarly you can estimate the probability of a price reaching a threshold whether it be a stock price or option strike price by; ln (expected price/ Price)/ (Volatility*sqrt (time)) ln = naperian logarith ln not log 10 This can be modified with the above formula to estimate the future probability, rather than immediate.

Stock Out Probability Formula To calculate the stock out probability, simply divide the number of stock outs by the number of demand requests, then multiply by 100.
What is the formula for expected stock price?
The formula is D+E/(1+R)^Y where D is any dividends expected to be paid during the period, E is the expected stock price, Y is the number of years down the line, and R is the real rate of return you estimated. Plug the numbers into the formula to complete your calculation.

Probability of Touching Calculator
This calculator provides such useful information that it should be used by all options traders, including very experienced ones, and it is referred to by more than one name. It could be called a "Probability of Touching Calculator" or a "Stock Price Probability Calculator." Ask your broker if they have such a calculator available for you to use.
Other Strategies
When you trade any options strategy with multiple legs (these are known as spreads), there is more than one option that matters. For example, in a typical butterfly spread, you own two different options.
Choosing the Holding Period
Another way to use this calculator is to decide how long to hold onto the position. By plugging a different number of "days" into the calculator, you can learn how the probability of touching changes.
Is it hard to value long established stocks?
On the other hand, long-established stocks, especially those that have a consistent record of dividend payments and increases, aren't too difficult to value -- at least in theory.
Can we predict the price of a stock in the future?
None of us has a crystal ball that allows us to accurately project the price of a stock in the future. However, if we make a few basic assumptions, it is possible to determine the price a stock should be trading for in the future, also known as its intrinsic value.

Drawing Probability Distribution
Discrete vs. Continuous Distributions
- Discrete refers to a random variable drawn from a finite set of possible outcomes. A six-sided die, for example, has six discrete outcomes. A continuous distribution refers to a random variable drawn from an infinite set. Examples of continuous random variables include speed, distance, and some asset returns. A discrete random variable is illustrated typically with dots or dashes, while …
Probability Density vs. Cumulative Distribution
- The other distinction is between the probability density function (PDF) and the cumulative distribution function. The PDF is the probability that our random variable reaches a specific value (or in the case of a continuous variable, of falling between an interval). We show that by indicating the probability that a random variable X will equal an actual value x: P[x=X]\begin{aligned} &P[x …
Binomial Distribution
- The binomial distributionreflects a series of "either/or" trials, such as a series of coin tosses. These are called Bernoulli trials—which refer to events that have only two outcomes—but you don't need even (50/50) odds. The binomial distribution below plots a series of 10 coin tosses wherein the probability of heads is 50% (p-0.5). You can see in the figure below that the chance of flippin…
Lognormal Distribution
- The lognormal distribution is very important in finance because many of the most popular models assume that stock prices are distributed lognormally. It is easy to confuse asset returns with price levels. Asset returns are often treated as normal—a stock can go up 10% or down 10%. Price levels are often treated as lognormal—a $10 stock can go up to $30 but it can't go down to -$10. …
Poisson
- The Poisson distribution is used to describe the odds of a certain event (e.g., a daily portfolio loss below 5%) occurring over a time interval. So, in the example below, we assume that some operational process has an error rate of 3%. We further assume 100 random trials; the Poisson distribution describes the likelihood of getting a certain number of errors over some period of ti…
Student's T
- The student's T distribution is also very popular because it has a slightly "fatter tail" than the normal distribution. The student's T is used typically when our sample size is small (i.e. less than 30). In finance, the left tail represents the losses. Therefore, if the sample size is small, we dare underestimate the odds of a big loss. The fatter tail on the student's T will help us out here. Eve…
Beta Distribution
- Finally, the beta distribution (not to be confused with the beta parameter in the capital asset pricing model) is popular with models that estimate the recovery rateson bond portfolios. The beta distribution is the utility player of distributions. Like the normal, it needs only two parameters (alpha and beta), but they can be combined for remarkable flexibility. Four possible beta distribu…
The Bottom Line
- Like so many shoes in our statistical shoe closet, we try to choose the best fit for the occasion, but we don't really know what the weather holds for us. We may choose a normal distribution then find out it underestimated left-tail losses; so we switch to a skewed distribution, only to find the data looks more "normal" in the next period. The elegant math underneath may seduce you into t…
