为什么要打板？这个问题涉及到股票交易的策略和技巧，以下是对这个问题的解析以及英文翻译对照：

首先，打板是一种高风险高收益的投资策略。在股票市场中，有些股票会出现连续涨停板的情况，这时投资者可以通过打板的方式买入涨停板附近的股票，等待其继续上涨后再卖出以赚取差价。虽然这种策略具有较高的风险，但一旦成功，收益也非常可观。英文翻译为：Firstly, hitting the board is a high-risk and high-return investment strategy. In the stock market, some stocks may experience consecutive涨停板, allowing investors to buy stocks near the涨停板 and sell them after they continue to rise to make a profit. Although this strategy has high risks, once successful, the returns can be significant.

其次，打板可以帮助投资者快速捕捉市场热点。在股票市场中，热点板块和股票经常会出现快速上涨和下跌的情况，而打板则可以帮助投资者快速买入这些热门股票，享受股价上涨带来的收益。此外，打板也可以避免投资者在市场回调时买入股票而遭受损失。英文翻译为：Secondly, hitting the board can help investors quickly capture market hot spots. In the stock market, hot stocks and sectors often experience rapid rises and falls, and hitting the board can help investors quickly buy these popular stocks and enjoy the returns of their价格上涨. Additionally, hitting the board can also prevent investors from buying stocks during market corrections and incurring losses.
