Above are some illustrations that you can review to try to get an idea of the semiconductor chain, as well an idea of historic sales data and valuation comparisons. Semiconductors have had a huge run as of late, about 80% or so since the March bottom but the Exhibit on the bottom shows that the valuation of the sector in general is still relatively cheap. Below is a list of all stocks that are semiconductors, segmented by niche focus (took tons of time, so I hope it's useful). As for my personal use, I will save this write-up under my favorites and keep this as a "shopping/research" list, although I know most well. I will accumulate more semiconductors on dips but own a good amount now.
