Regression

So I work for an IB in Brazil. ~I´m doing this DCF model which I´m regressing GDP against the growth of the market for the past 10 years.

GDP growth averages 3.64%, sector growth averaged 4.32%. I did this regression using excel and R2 IS KIND OF LOW, AROUND 0.35 , but anyways , the slope of the line comes to about 0.7…

Meaning I am projecting the market to grow about 70% of GDP, but that just seems really counter intuitive for me, since on average the market grew more than GDP…

Any help? I´m a little rusty on this
