Every stock market investor should be concerned about the impact that rising interest rates might have on future investment returns. The prevailing theory is that when interest rates rise then stock prices should decline due to the impact to earnings from higher borrowing costs. Since we are at or near the lowest level in interest rates, conventional wisdom suggests that eventually interest rates will rise.
With rising interest rates, investors should expect that stock prices will decline as per share earnings are reduced. One industry that borrows heavily for going operations is the utility sector (electricity, water, gas etc.). This article will give a cursory examination of utility stocks from the beginning of a rising interest rate cycle to the peak (1939 to 1980). We will attempt to determine if the conventional thinking on rising interest rates and their impact on utility stocks is correct.
