The search for market excesses can probably start small – in fact with the smallest stocks that have seen outsized gains so far in 2021 as well as record trading volumes.

Already in 2021, companies with a market capitalization between $50 million and $300 million, as measured by the Russell Microcap index, are on a tear. The group has risen just shy of 10% with January only half over, part of a 12-month trend that has seen the gauge soar 31%.

In fact, the gains so far this year have set a record for the index that goes back to 2007.
