** AlphaValue upgrades Spanish engineering firm and infrastructure operator Sacyr SCYR.MC to "add" from "sell", citing its consistent strategy, strengthening cash generation and expanding concessions
** The broker says the company is now "ready to harvest cash" with its business mix becoming more concession-led, which offers better visibility and a lower risk profile
** Sacyr "remains a defensive stock in nature, given the long-duration and infrastructure-backed profile of its assets", AlphaValue adds
** The brokerage raises Sacyr's target price to 5.08 euros ($5.87), which is around 23% higher than its Thursday's trading price
** Including the session, the stock has gained about 9% since the beginning of the year
($1 = 0.8653 euros)
