The negative feedback loop that has rocked our world for the past two years gives way to a more uplifting view of things. As my cousin Harold likes to say, “Every day that I wake up on the right side of the grass is a good day.” The stock market celebrated April by welcoming all news that was less terrible than expected as a major victory. The Wall followed suit by mercifully losing two worries. But it’s still worth keeping an eye on a financially wobbly Eastern Europe and the growing unrest in Pakistan. For now, though, the stock market glass is half full; buying begets buying, and up is good.
