美伊协议后市场反弹

We need to translate the given English description into Simplified Chinese, preserving numbers, percentages, dates, ticker symbols, acronyms, proper nouns, etc. Must output only the translated description, no extra commentary. Must keep the marker '' at the end unchanged. Must not use pinyin. Must keep EPS, P/E, RSI, IPO, ETF, EBITDA, ROE as is, but they aren't present. Must preserve numbers, percentages, dates, ticker symbols ($AAPL). There's no ticker symbols in the text except maybe S&P 500 Index, Dow Jones Industrial Average, Nasdaq 100 Index. Those are proper nouns; we can translate them appropriately but keep them as is? The instruction: "Keep proper nouns (company names, person names) in their conventional target-language form." S&P 500, Dow Jones, Nasdaq are indices; they have conventional Chinese names: "标普500指数", "道琼斯工业平均指数", "纳斯达克100指数". We can translate them but keep numbers. Also "Wall Street analysts" maybe "华尔街分析师". "Fed" maybe "美联储". "Intel" and "Microsoft" are company names; we can translate them as "英特尔" and "微软". Keep percentages, numbers. Keep "EPS" etc not present. Keep "ETF" not present. Keep "P/E" not present. Keep "RSI" not present. Keep "IPO" not present. Keep "EBITDA" not present. Keep "ROE" not present.

We must preserve the marker at the end exactly: ''.

We must output only the translated description, no extra text.

We need to keep similar information density, may be slightly shorter or longer.

We must use Simplified Chinese characters, formal style like Caixin, Yicai.
