The PSI (Portugal Stock Index) maintained its opening trend around 9:30 a.m. in Lisbon, climbing 0.22% to 9,162.92 points, with 11 companies rising, three falling and two maintaining their price (CTT at €6.39 and Teixeira Duarte at €0.42).

The main European bourses opened higher on Tuesday, despite investor fears regarding the impact high energy prices could have on inflation data.
The euro traded lower, falling 0.22% to $1.1630 on the Frankfurt foreign stock market.
The price of Brent Crude, Europe's benchmark for July delivery, fell 1.57% to $110.34 as negotiations between Washington and Tehran failed to progress.
Brent fluctuated between $107 and $113 a barrel on Monday amid rumours of dialogue in the Middle East (including a gradual reopening of the Strait of Hormuz, a long-term freeze of Iran's nuclear programme instead of a complete dismantling, and the transfer of enriched uranium to Russia), which later gave way to doubts about an imminent agreement after the White House considered Tehran's latest proposal highly insufficient.
US President Donald Trump said in a statement that, at the request of Qatar, Saudi Arabia and the United Arab Emirates, he would not carry out the attack on Iran he had planned for Tuesday and would postpone it by two or three days, because the leaders of those countries believed serious negotiations would result in an agreement acceptable to all parties.
Trump again threatened a major attack otherwise.
Iran warned the US on Tuesday not to make another "miscalculation" and said its armed forces had their "fingers on the triggers" to respond in a "fast, firm and powerful" manner to any new aggression.
Dow Jones and Nasdaq futures pointed to declines of 0.04% and 0.15%, respectively, at the same time in Lisbon.
