Answer:
B
Explanation:
I think you've already figured this out for yourself, but I thought I'd answer anyway and maybe clarify some things.
Supply is the total amount of a <u>good or service</u> that is available to consumers.
- Think about it: goods are physical things bought and sold, like apples. Services are actions done for another person, like taxi driving or renting a used car.
- None of the other answers make sense: a "device" is not a strictly defined term in economics; an "industry" can't be available to consumers, and a "warranty" isn't applicable.
Answer:
The correct answer is letter "D": All securities in an efficient market are zero net present value investments.
Explanation:
The Efficient Market Hypothesis (EMH) states that neither public or insider information cannot help in an attempt to beat the market because stocks already show all available information possible. Thus, neither using technical or fundamental analysis could be useful to predict future stock price movement.
<em>In other words, in a market under EMH all stocks are zero Net Present Value (present value inflows minus present value outflows) investment vehicles.</em>
Bank interest is when you leave money in the bank for saving purposes. Then the money stays in the bank and you get money for keeping your money in the bank.
Answer:
D) Stock prices of companies that announce increased earning in January tend to outperform the market in February.
Explanation:
The above is consistent with the Efficient Market Hypothesis. All others are a direct contravention.
<em>The efficient market hypothesis (EMH), also known as the efficient market theory, is a hypothesis that states that the prices of shares contain all information and that consistent alpha generation is impossible.</em>
According to the hypothesis, stocks always trade at their fair value on exchanges, making it impossible for investors to purchase undervalued stocks or sell stocks for inflated prices.
This means that it should not be possible to outperform the overall market through professional stock selection or market timing.
The only way according to EMH that an investor can obtain better returns is by purchasing riskier investments.
By implication, this also means that it is not possible to "beat the market" consistently on a risk-adjusted basis since market prices should only react to new information.
You would note that in the option D, earning (which is a key driver for demand of stock) is announced in one month. The natural reaction would be for the demand for that stock to surge in the next month.
