Stock Market Yo-Yo

Up today and down tomorrow. The stock market seems to be constantly reacting to good news and bad news, sometimes “because of” the news and other times “despite” the news. In this research, we explore the portion of days that the market is up compared to the number of days it is down. Over the past five decades, through secular cycles, decades, and individual years, the range of up-days versus down-days is relatively close to 50%.
