Over the last five years, the Tesco (LSE:TSCO) share price has quietly doubled. Group sales came in at £16.8bn, with UK like-for-like sales up 1.8% on top of an exceptionally strong prior year period. The team at Morgan Stanley issued an Overweight rating with a 560p share price target – around 18.9% higher than where Tesco shares are trading today. So with plenty of wind in Tesco's sails, is this a cheap stock worth considering today? While far from disastrous, like-for-like sales fell 3.2% during the first quarter, partly reflecting a lower-margin contract exit and some unfortunate prior-year comparatives.
