左则建仓，在投资领域中，通常指的是在市场下跌时买入，即“买跌”。这与“右侧建仓”相对，后者是指在市场上涨时买入，即“追涨”。

在下跌的市场中，投资者选择左侧建仓往往基于对市场的深入理解和预期。他们认为市场虽然当前处于下跌趋势，但未来可能会反弹或反转。通过在市场下跌时买入，投资者可以降低平均成本，并在市场反弹时获得更高的回报。然而，这种策略也存在风险，因为如果市场继续下跌，左侧建仓的投资者将面临巨大的损失。

左侧建仓的优点在于可以利用市场下跌带来的低价机会。当市场价格下跌时，投资者可以以更低的价格买入更多的股票或其他投资产品。此外，左侧建仓也可以帮助投资者避免错过买入机会。在市场上涨时，许多优质的投资机会可能会被抢购一空，而左侧建仓则可以在市场下跌时提前布局。

然而，左侧建仓也存在一些缺点和风险。首先，预测市场走势是非常困难的。市场可能继续下跌，导致投资者损失惨重。此外，左侧建仓需要投资者具备较高的风险承受能力和耐心。在市场下跌时，投资者需要保持冷静，不被恐慌情绪左右，坚定自己的投资计划。

总的来说，左侧建仓是一种高风险、高收益的投资策略。它需要投资者具备丰富的投资经验和市场判断能力，同时还需要有承受市场波动和不确定性的心理素质。对于初次接触投资的人来说，建议在充分了解市场和投资产品的基础上，谨慎选择适合自己的投资策略。

英文中“什么叫左则建仓”可以翻译为“What is meant by “buying the dip”?”。 In the investment world, “buying the dip” typically refers to buying when the market is下跌, or “买跌”. This is opposed to “buying the rally”, which occurs when one purchases during上涨in the market, or “追涨”.

When the market is下跌, investors who choose to buy the dip often base their decision on in-depth market understanding and expectations. They believe that, despite the current下跌trend, the market may rebound or reverse in the future. By buying during下跌, investors can reduce their average cost and potentially achieve higher returns when the market rallies. However, this strategy also carries significant risks, as continued下跌in the market could result in significant losses for investors who choose to buy the dip.

The advantages of buying the dip include taking advantage of lower prices created by下跌in the market. When prices decline, investors can purchase more shares or other investment vehicles at lower costs. Additionally, buying the dip can help investors avoid missing out on investment opportunities. When the market is上涨and prices are increasing, many quality investment opportunities may be snapped up quickly, while buying the dip allows investors to take early positions during下跌.

However, there are also disadvantages and risks associated with buying the dip. Firstly, predicting market movements is extremely difficult. The market could continue下跌, leading to significant losses for investors. Additionally, buying the dip requires investors to have a high tolerance for risk and patience. During下跌in the market, investors need to maintain冷静and avoid succumbing to panic selling, staying committed to their investment plan.

Overall, buying the dip is a high-risk, high-reward investment strategy. It requires investors to have extensive investment experience and market judgment, as well as the psychological strength to withstand market volatility and uncertainty. For those new to investing, it is advisable to fully understand the market and investment products before making谨慎choices that are suitable for their investment strategy.
