(a) Buffett is clever and by reading the news and financial reports he is able to buy under-priced stocks and sell over-priced stocks. This provides evidence for rejecting the semi-strong and strong form EMH.

(b) Buffett was lucky, his strategy happened to be the right one, not due to its merits, just by chance. This provides no evidence for or against the weak, semi-strong or strong form EMH.

(c) Buffett’s investment strategy exposes investors to higher undiversifiable risk than the market and therefore deserves a higher return. This provides no evidence for or against the weak, semi-strong or strong form EMH.

(d) Buffett is an insider trader and is able to make money from his private information. This provides evidence for rejecting the semi-strong and strong form EMH. (Note: Warren Buffett is not an insider trader, he is an honest philanthropist, but assume the contrary in this answer option).

(e) Buffett may not have beaten the market because the graphs ignore dividends - the S&P500 is the price index rather than the accumulation index and BRK pays no dividends, so even though BRK has a higher capital return than the S&P500, the total returns could be equal. This provides no evidence for or against the weak, semi-strong or strong form EMH.

(a) Right now, borrow USD in America, convert it into EUR at the spot, lend it in Germany and lock in to buy USD and sell EUR forward one year. One year later, withdraw the EUR, convert it into USD and pay back the USD loan.

(b) American debt may be under-priced, buy it.

(c) German debt may be over-priced, sell it.

(d) The spot EUR may be over-priced compared to the USD, sell the EUR now.

(e) The forward EUR may be under-priced compared to the USD, lock in to buy the EUR in one year.
