Yes. Collective bargaining is negotiation of wages working conditions by an organized group of employees (often called a union). The union representatives meet with the employer/employer's representatives to negotiate terms.
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.
