A few days ago, I noticed that the concept of brain-computer interfaces is particularly hot. Let's review what the technical aspects are all about.

**Brain-Computer Interface: Is There a Fifth Wave?**

At the beginning of this week, positive news drove the market, and the brain-computer interface jumped open sharply. On Tuesday, it continued to gap up, and then it started consolidating over the next few trading days. From the daily chart, the trend shows a typical wave progression—rapid rise in the past few days followed by oscillating consolidation. According to wave theory, this rhythm suggests there might still be room for a fifth wave upward on the daily chart. So, next week, we should keep an eye on this direction.

**Photovoltaic Equipment: Hidden Opportunities on the Weekly Chart**

Speaking of photovoltaics, some negative news came out over the weekend, which indeed puts short-term pressure on the sector. But from a weekly perspective, the current position of photovoltaic equipment is already at a clear low point. More importantly, the main players' intentions are very clear—they have been continuously moving upward for four trading days starting from Monday. Although there was a pullback on Friday, this rhythm indicates that funds are still choosing to enter.

Another point worth noting is that recently, the commercial space sector has been particularly hot. If photovoltaics can be combined with space exploration, the new concept of space-based photovoltaics could be hyped up. Such thematic integration often sparks new imagination in the market.

However, the sector's trend is very susceptible to various factors, and short-term news impacts can be significant. So, these analyses are purely discussions of market trends and may not be entirely accurate. Everyone should make their own judgments and not treat this as investment advice.
