Suggest you READ the details in those reports. Would you say MS raising the price target to $76 is an upgrade? How about if you realized the old target was $70 and EPD at the time was already at $74 +/-.
Long ago, I came to the conclusion that analyst price targets are meaningless. As long as the earnings and distributions keep growing, the price targets will keep rising. I'd rather use a downside price target to know when to buy more units for the next move up.
