inefficient

- An investor evaluated a firm's past stock data and determined that the price always rose on the Tuesday after a 3-day weekend - She purchased the stock on the Friday before such a weekend and sold it on Tuesday for an abnormally large gain This outcome suggests that the market is...

weak form market efficiency

- Security prices reflect all information found in past prices and trading volume - If the weak form of market efficiency holds, technical analysis is of no value; investors cannot earn abnormal returns by studying past data - Since stock prices respond only to new information, which by definition arrives randomly, stock prices are said to follow a "random walk"

Strong form market efficiency

- Security prices reflect all information—public and private - Strong form efficiency says that anything pertinent to the stock price and known to at least one investor is already incorporated into the security's price - If the strong form holds, even private (inside) information is of no value

semi-strong form market efficiency

- Security prices reflect all publicly available information, including: - Historical price and volume information - Published accounting statements - Information found in annual reports - Press releases and news articles - If the semi-strong form of market efficiency holds, published information is of no value

efficient market hypothesis (EMH) implications

- because information is instantly reflected in stock prices, learning information when it is released has little to no benefit - firms should expect to receive the fair value for securities that they sell, but cannot profit by fooling investors

treasury notes/bonds

- long term instruments (mature in up to 30 years) - pay semi-annual coupons like corporate bonds free of default risk

treasury bills

- short term instruments (mature in a year or less) - do not pay interest; rather, they are sold at a discount from face value

arithmetic mean

- the average return earned in any particular year - necessary to calculate standard deviation - overly optimistic

geometric average

- the equivalent compound annual growth rate - employed in TVM calculations - overly pessimistic for short time horizons

10 to 20

A projected IRR on a risky investment in the _____ percent range is not unusual.

Blume's formula

If you are forecasting a few decades in the future (as you might do for retirement planning) you should calculate the expected return using:

risk-free rate

real risk \-free rate + infaltion

efficient capital market

stock prices full reflect available information - there are no surprises

compounding

risk
