VHT is the ticker for Vanguards healthcare ETF that seeks to track the MSCI US IMI Health Care Index. I use this ETF as part of my long term investing strategy to gain exposure to the US healthcare sector which I believe will experience greater growth and lower drawdowns then the general market over the next 20-30 years. The reason I believe this is because populations are ageing in combination with unhealthy lifestyle habits. This has lead to people living longer in conjunction with chronic or complex medical conditions that require advanced and expensive treatments to manage them. As with any long term investing strategy it is not especially useful to attempt to time the market but it is helpful to make additional purchases at reduced prices when headwinds cause market sell offs. I believe VHT is at such a level now, it has been unable to break below previous resistance turned support and is sitting just above the 200 day moving average. While the price may still move lower as there are considerable market headwinds currently, I am happy to continue to purchase additional equity in this ETF as it moves into any future support zones.
