What determines the market's direction each day? Jobs Data, manufacturing reports, interest rates, war, government conferences, etc. . . . ? I think it's the weather more than anything else. Today its raining, the market is down. Thursday it will be sunnier, the market will go up. Freak blizzard in April, the market goes down. Sweltering heat in July, market goes down. Flowers blossoming and birds chirping in May, market will go up. That's what I think.
