The Taiwan Weighted Index is the benchmark of the Taiwan stock market that everyone often hears about. It is calculated using market capitalization weighting, so larger companies have a greater influence.

This index is quite interesting. It reflects the overall market situation and can be seen as a mirror of Taiwan's economy. Large companies have a higher weight in it, and giants like TSMC carry significant weight.

Investors seem to really like keeping an eye on this index. It feels like it can provide some clues about market trends. Many funds also use it as a benchmark.

However, this index is not perfect. It may overlook the performance of smaller companies. Sometimes, the price fluctuations of one or two large companies can cause the index to fluctuate.

Overall, the Taiwan Stock Weighted Index is still quite important. However, when using it, it's best to also consider other factors. After all, who can predict the stock market?
