[2] On the other hand, Professor Jeremy Siegel analyzed the Nifty Fifty era in his book Stocks for the Long Run, and determined companies that routinely sold for P/E ratios above 50 consistently performed worse than the broader market (as measured by the S&P 500) in the next 25 years, with only a few exceptions.

The confidence interval can be expressed in terms of statistical significance, e.g.: "The 95% confidence interval represents values that are not statistically significantly different from the point estimate at the .05 level." [20] Interpretation of the 95% confidence interval in terms of statistical significance.
If x is measured at the precision of a single year, we can construct a separate 95% confidence interval for each age. Each of these confidence intervals covers the corresponding true value f(x) with confidence 0.95. Taken together, these confidence intervals constitute a 95% pointwise confidence band for f(x).
The NIFTY 50 index is a free float market capitalisation-weighted index.. Stocks are added to the index based on the following criteria: [1] Must have traded at an average impact cost of 0.50% or less during the last six months for 90% of the observations, for the basket size of Rs. 100 Million.
A confidence interval states there is a 100γ% confidence that the parameter of interest is within a lower and upper bound. A common misconception of confidence intervals is 100γ% of the data set fits within or above/below the bounds, this is referred to as a tolerance interval, which is discussed below.
Classically, a confidence distribution is defined by inverting the upper limits of a series of lower-sided confidence intervals. [15] [16] [page needed] In particular, For every α in (0, 1), let (−∞, ξ n (α)] be a 100α% lower-side confidence interval for θ, where ξ n (α) = ξ n (X n,α) is continuous and increasing in α for each sample X n.
NSE's flagship index, the NIFTY 50, is a 50 stock index that is used extensively by investors in India and around the world as a barometer of the Indian capital market. The NIFTY 50 index was launched on April 22, 1996 by NSE with a base value of 1000 on the base date of Nov 3, 1995. [10] [11]
Robert Shiller's plot of the S&P composite real price–earnings ratio and interest rates (1871–2012), from Irrational Exuberance, 2d ed. [1] In the preface to this edition, Shiller warns that "the stock market has not come down to historical levels: the price–earnings ratio as I define it in this book is still, at this writing [2005], in the mid-20s, far higher than the historical average
