这是 Bloom Energy,一只非常热门的股票,它之所以出名是因为 Nancy Pelosi。嗯,这是部分原因。Bloom Energy 本身也有很有意思的业务,但来看看这里的技术分析。
Here's Bloom Energy, a very popular stock that gained its fame because of Nancy Pelosi. Well, that's part of the reason. Bloom Energy also has an interesting business, but take a look at the technical analysis here.
你看,当 Bloom Energy 在某个区间内横盘整理时,布林带相当窄。它稍微小一点,并不很宽。然后,当 Bloom Energy 经历大量波动、开始向下交易并面临大量负面动能时,布林带就显著扩大了。
它在下跌期间会明显变宽。这是因为波动越大,意味着该股未来有更多可能进一步移动,无论是向下还是向上。
See, when Bloom Energy was moving sideways within a certain range, the Bollinger Band was fairly narrow. It was a little smaller and not very wide . Then, when Bloom Energy experienced a lot of volatility and started trading downwards and facing a lot of negative momentum, that's when the Bollinger Band widened significantly .
It widens noticeably during downturns. That's because more volatility means there are more possibilities for the stock to move further in the future, either downwards or upwards.
