What is the efficient market hypothesis (EMH)?
The idea that stock prices fully reflect all available information
What does the efficient market hypothesis (EMH) suggest about technical analysis?
It is useless because past price patterns cannot predict future returns

As long as policies are fully disclosed, markets adjust for differences
Why does lack of comparability in accounting policies not necessarily affect share prices?
Investors can adjust for accounting differences if information is transparent
