$1.$ Recall the ppt slide from the Chap $5$ lecture below that shows various

asset class returns over the $18-$year period. Note that in some years low$-$risk assets such as cash & US Gov$$t bonds outperformed high$-$risk assets such as US & non$-$US equities. In chapter $1,$ we learned an implication of no$-$free$-$lunch is the risk vs$.$ return trade$-$off. Do the returns shown in the table below dis$-$prove no$-$free$-$lunch?
