One more thing to add to that is the fact that I often mention my preferred leverage ETF if covering a sector in a video or when covering the sector as a trade idea, whether include the leveraged or inverse ETF as an official trade idea or just mention it as an alternative to the 1x non-leveraged sector ETF. With that being said, feel free to ask me if I have a preferred leveraged or inverse ETF when covering a sector as I often do, typically those that have the most liquidity as I find it best to avoid some of the less actively traded ETFs due to the large spreads which can cost you $$ when buying & selling.

I know most but not all of the long & short ETFs for the various indexes & sectors that I cover but it would be an arduous task to list them all with each sector or index ETF that I cover. Plus there many have at least two of the following: 1x (non-leveraged) long & short ETFs, long & short 2x leveraged and many also have both long & short 3x leveraged ETFs not to mention that a lot of sectors have numerous 1x & even 2x tracking ETFs (e.g.- for just the long/bullish 1x non-leveraged tracking ETFs, the semiconductor sector has at least 3; SMH, SOXX & XSD).

Regarding the biotechs, there are at least 3 non-leveraged long ETFs: XBI (mentioned above), IBB & PBE. There also BIB (2x long) & BIS (2x short) biotech ETFs which track the same Nasdaq Biotech Index as IBB. You can also juice up the Nasdaq Biotech index to 300% leverage with UBIO (3x long) & ZBIO (3x short). Then you have LABU & LABD which are the 3x long & 3 short biotech sector ETF that track the same biotech index as XBI does.

I’ll make a note to update the ETF Center to both include the latest ETF offerings asap. Until then, the site that @jamske mentioned sounds like a good resource to get the latest listing of ETFs for each sector, index or commodity.
