Answer:
✓Technical analysis cannot
✓fundamental analysis cannot
Step-by-step explanation:
The efficient-market hypothesis can be regarded as hypothesis in financial economics, this hypothesis stress it that asset prices will definitely reflect all available information. This implies that "beating the market" consistently on a risk-adjusted basis is quite impossible, since price in the market
supposed to react to new information only.
this theory comes in different versions such as;
✓weak
✓semi-strong
✓ and strong.
The semi-strong form has the belief since calculation of a stock's current price is been done using information that is public, utilization of technical or fundamental analysis by investors to gain higher returns in the market could be impossible.
It should be noted the semistrong-form of the efficient market hypothesis implies that Technical analysis cannot
generate abnormal returns and fundamental analysis cannot
generate abnormal returns.
