I agree that Tesco, based on the performance over the past years, is definitely not an outstanding investment. But there was the little window where there was an opportunity to make a speculative investment to achieve a short term gain. A more steady retailer is Home Retail Group who saw a drop in value on the announcement of the closure of some Homebase Stores, but then have seen a steady rise on the announcement of the new plans for the Group, which includes Argos Stores. Definitely a better bet than Tesco!
