Three ibex 35 shares start May with potential of more than 50% in the stock market

In spite of a very moved in the markets by the commercial war initiated by Donald Trump, the IBEX 35 has managed A accumulated revaluation of 14%. Of course, optimism has been deflated a little since at the end of March it reached a maximum closure of 13,484.30 points (Intradiary maximum of 13,515,10), located at levels that had not stepped on since 2008.

But if we listen to fundamental analysts, it seems that in the Madrid parquet there are still good purchase opportunities, especially for those most focused in the long term. According to data collected by Reuters, No less than 18 of the 35 Ibex components have a double digit potential 12 months seen. Of these, 13 exceed 20% of the bullish route, in nine is exceeding 30%, in five to 40% and In three of them, 50% is exceeded.

As in previous months, the action that offers more potential in the IBEX 35 is Grifols. According to Reuters data, the Alcista potential is 83.51% up to an average target price of 15.51 euros.

And, when it seemed that the value began to overcome in the stock market, with a strong advance in the start of 2025, in the last two months it has lost bellows and is already clearly located with a negative balance (-7%) in the accumulated of the year. The company is still trying to move away the ghosts that stalked it last year – a caid of more than 40% – with a turn not only in governance, but also in the policy of compensation to the shareholder.

Also a very high potential presents Solaria, a company that continues to suffer in the parquet, with a drop accumulated in 2025 of 14.5% after last year lost almost 60% in the parquet. The pressure on the sector of the renewable companies, which has been exacerbated by the turn in American politics after Trump’s landing in the White House, partly explains this behavior.

The company is in the process of transformation from a photovoltaic company to one that also covers infrastructure, data centers or energy, and it seems that at least analysts trust that it manages to turn around the situation. According to Reuters data, it presents a 73.59% bullish potential. Specifically, they place their target price on the 11.53 euros per share.

With a 51.07% potential Red Laboratories is located, which is the red lantern of Ibex 35 so far from 2025, with a drop of 17.5%. Much of the fault of this behavior is the ‘profit warning’ that launched in mid -February warning of “a lower activity of the planned” in its manufacturing business to third parties (CDM) during the fourth quarter of last year. The shares have fallen by 21.5% since its maximum of February 6, but analysts trust the rebound, placing its average target price at 78.33 euros.

Without reaching 50% of the potential, but rozing it (+47,4%) is IAG (Iberia). The airline holding, which last year practically doubled its price, has fallen by 14.3% so far from 2025, but could overcome the medium and long term flight until reaching an average assessment of 4.59 euros per share.

Values with negative potential

Analysts are much more prudent regarding other values. Up to eight ibex 35 actions have a negative potential, that is, that the assessment of analysts is lower than the current price.

As in previous months, analysts are especially pessimistic about ACS: they give an objective price of 49.28 euros that are 10.15% below of your current quotation. The construction company that presides over Florentino Pérez has had a modest start compared to IBEX 35, although the accumulated rise is more than 14.2%.

It also touches the -10% Mapfre, which has had a strong acceleration in recent weeks that seems to have caught the analysts. The insurer has risen 28.8% so far this year, with no less than 22% since April 7, but experts place their target price at 2.87 euros, 9.18% below of the current contribution.

If the focus on the best values of the IBEX 35 is placed so far this year, Indra is the main protagonist of the parquet, with A strong rise of more than 60% in the heat of the plans of European governments (including Spanish) to boost defense spending to adapt to the new geostrategic map. However, analysts give it an additional moderate potential, of and 2.12% up to an average target price at 28.39 euros.

Behind Indra are the Ibex banks, all of them with accumulated increases of more than 30%. However, the bullish potential that analysts see is moderate, although it stands out 6% that give Banco Santander to an objective price of 6.62 euros. The entity chaired by Ana Botín has risen more than 40% so far from 2025.
