The short answer is that you can't – There is no working mechanism in place to allow this.

I figured out a way around this — I get the chart set with all of the charting options I want, then I bookmark it (or add to favorites). Then I use my bookmark to enter the charts rather than the Yahoo provided links. — Not an elegant solution, but if you make a lot of changes to the default chart, it sure beats doing all the chart set up repeatedly.

Beta
The measure of a fund's or a stock's risk in relation to the market or to an alternative benchmark. A beta of 1.5 means that a stock's excess return is expected to move 1.5 times the market excess returns. E.g., if market excess return is 10%, then we expect, on average, the stock return to be 15%. Beta is referred to as an index of the systematic risk due to general market conditions that cannot be diversified away.

Beta equation (security)
The market beta of a security is determined as follows: Regress excess returns of stock y on excess returns of the market. The slope coefficient is beta. Define n as number of observation numbers. Beta =
[(n) (sum of [xy]) ]-[ (sum of x) (sum of y)]/
[(n) (sum of [xx]) ]-[ (sum of x) (sum of x)]
where: n = # of observations (usually 36 to 60 months)
x = rate of return for the S&P 500 index
y = rate of return for the security

If i remember correctly, the Beta coefficient measures correlation. Thus, you can use it to discuss how market factors affect the stock price of your company. If the market is volatile and the company's movement is highly correlated, the company must implement actions that could hedge or protect against these fluctuations.

I too suddenly lost the Yahoo Beta chart capability. A search led me to the following page that gave me beta charts. Go to this page and enter your stock symbol to get beta charts. You'll will subsequently got beta charts for other stocks. Please try:

Two questions. First, why would anyone own this company? Having looked at the fundamentals, I am not sure it will survive as a going concern.

Second, beta charts will never occur. Beta uses the partial derivative, estimated by regression, but cannot actually know the partial. As a partial, it also strongly fails as an estimator. Since regression is the basis of beta and the assumptions of the regression are strongly violated, the measure itself has no meaning.

Beta is going to disappear from finance.

haha..
2:30 “to calculate beta you need this big computer..”
haha
beta= ratio of st. dev on your stock under consideration to st dev of major index (proxy for mkt) times coeff. corr between rates of return on your stock relative to rates of retrun on your market proxy say: S&P 500 , or better NYSE (2000 stocks)
anyway
or just Cov bet stok and mrk, diveded by variance of mkt
simple as that .. no computers no nothing, hahaha
though it’s a cool video
really funny one
thank you
