5 月 20 日，美国天然气期货飙升约 10%，原因是预计下周需求将增加，长期预测今年夏季气温将高于正常水平，以及一些分析师所称的技术性反弹，导致日产量下降。

5 月 19 日，天然气价格下跌约 7%，收于 200 天移动平均线以下，一些分析师表示，这可能促使一些技术交易员开始购买天然气。

“有时候技术交易员比基本面交易员更有影响力。有时新闻不多，计算机和算法就能无视基本面因素，推动价格上下波动，最终基本面开始发挥作用，”Price Futures Group 分析师 Phil Flynn 表示。

U.S. natural gas futures soared about 10% on May 20 on a decline in daily output on forecasts for more demand next week, long-term forecasts for a hotter-than-normal summer and what some analysts called a technical bounce.

Gas prices fell about 7% and closed below the 200-day moving average on May 19, which some analysts said likely prompted some technical traders to start buying gas.

"Sometimes technical traders have more power than the fundamental guys. There are times where there is not a lot of news and computers and algorithms can drive the prices up and down regardless of the fundamentals, and then ultimately the fundamentals start kicking in," said Phil Flynn, an analyst at Price Futures Group.
