I believe the world is at an early stage of a transformational technology revolution. Semiconductors are central to this revolution so although the industry has a boom and bust quality I believe the secular trend is strongly higher. The last two months have seen a sharp sell-off but ETFs don't go bust and have a track record of rebounding to new highs. I think this is a good time for bold investors to buy ETFs that track an index of semiconductor shares. Two are listed above. The 3x leveraged version is obviously for very bold investors.
