Apple stock historically bottoms out at higher earnings yields

In last 20 years, apple stock has 'bottomed' out at earning yields in the 6-10% range. However, in the past it was a smaller company with a high growth rate potential. Current earnings yields on apple are in the 4% range and now its a near 3 trillion dollar company. I dont know if thats an apples to apples comparison ;) AAPL QQQMSFT
