Go long XSVMXSVM is an excellent ETF to give you exposure to a large variety of quality small-cap stocks. It has a low expense ratio and has a good set of holdings. Its largest holding is Gamestop, but the pain should sort itself out over the next week. I would start a position in this and continue to load the boat as it approaches the lower end of the trend line.
The small-cap value area of the market should do well in the years to come, the imminent stimulus bill should throw some more gasoline on the fire.
This is a long-term hold, 3-5 years at least. It should work out relatively short-term, say to the end of 2021; but this is an investment vehicle that is best to average into overtime for long-term gains and appreciation.
