Ferroglobe shares surge 13.3% after-hours as EU imposes safeguard measures on ferroalloy imports.

think> Okay, let's tackle this query. The user wants me to act as a financial analyst explaining a stock price movement based on recent news. The stock in question is Ferroglobe (GSM), which surged 13.3% in after-hours trading. I need to link this movement to the provided news events. First, looking at the stock performance: it's a significant increase after hours. The main news provided has two reasons. Reason 1 is about the EU imposing safeguard measures on ferroalloy imports, which Ferroglobe's CEO mentioned would help their European business. The article states that GSM's stock surged 18% on Tuesday due to these EU measures. The second reason is a series of news about stock transactions and earnings reports, but they seem older and less relevant to the recent surge. I need to determine which news is relevant. The first reason clearly relates to the EU's action, which is a major regulatory change affecting the industry. The second reason includes older news (from August to May 2025) about earnings, institutional investments, and other factors, but these don't seem to directly cause a 13.3% jump in after-hours trading on the specific date mentioned. The key here is the EU's safeguard measures, which were recently announced and directly impact Ferroglobe's market conditions in Europe. The CEO's comments also align with the positive outlook. Now, checking if the direction matches. The news about EU measures is positive for Ferroglobe, as it limits cheap imports that were hurting their sales. This would logically lead to a stock price increase. The after-hours trading period is specified, so I need to mention that in the summary. I need to ensure the summary is concise, under 150 words, and follows the Bloomberg style. Round the percentage to two decimals (13.30% becomes 13.30% but the example shows two decimals, so 13.30% but the input is 13.29787234%, which rounds to 13.30%). Wait, the example shows 4.23% as the rounded value. Let me check: 13.29787234% rounds to 13.30% when keeping two decimal places. But the example shows 4.23% from 4.230769%, which is rounded to two decimal places. So here, 13.2978... should be 13.30%. However, the user's instruction says to round to two decimal places and remove trailing zeros. If it's exactly 13.30%, maybe it's written as 13.30% or 13.3% if trailing zero is removed. Wait, the example shows 4.23% which is two decimals, but if the value was 4.2, it would be 4.20% but they remove trailing zeros, so maybe 4.2%. But the input here is 13.2978... which rounds to 13.30% (two decimals). However, the user says to remove trailing zeros. If the value is 13.30%, perhaps it's written as 13.3%. Let me check the example again. The input was 4.230769% which becomes 4.23% in the output. So for 13.2978..., it's 13.30% but since the third decimal is 7, it rounds up the second decimal from 29 to 30. So 13.30%. But the instruction says to remove trailing zeros. If it's 13.30%, then the trailing zero can be removed, making it 13.3%. But maybe the user wants exactly two decimal places regardless. The example shows two decimals. So perhaps I should present it as 13.30%, but given the instruction says to remove trailing zeros, maybe 13.3%. Hmm, the example shows 4.23% from 4.230769%, so they kept two decimals. So for 13.2978..., rounding to two decimals gives 13.30%. But the instruction says to remove trailing zeros. If the value is 13.30%, then it's 13.30% but with trailing zero, but maybe the user wants to present it as 13.3%. Wait, the example shows 4.23% as the output, which is two decimals. So perhaps the user wants two decimal places regardless of trailing zeros. So 13.2978... becomes 13.30%. However, in the example, the input was 4.2.
