5. Canopy Growth Corp. (NASDAQ:CGC)
Canopy Growth extended its winning streak to a third consecutive day on Monday, jumping as high as 15.7 percent during the day before closing at $1.44, after an analyst’s bullish rating on one of its peers spilled over to its stock.
In a market note, Jefferies gave Tilray Brands Inc.—one of Canopy Growth Corp.’s (NASDAQ:CGC) counterparts—a “buy” recommendation with a higher price target, saying that it would benefit from a potential rescheduling of cannabis use to a lesser federal restriction.
Earlier this month, President Donald Trump said that his administration was looking to loosen federal restrictions on the use of cannabis, which would see the likelihood of reclassifying it to Schedule II from I at present.
Drugs under Schedule II are classified with a high abuse risk but also have safe and accepted medical uses in the US.
Meanwhile, Schedule I drugs, where cannabis currently falls under, are those with a high abuse risk, without any safe and accepted medical use.

In a regulatory filing on Monday, Richtech Robotics Inc. (NASDAQ:RR) said it entered into a two-year master services agreement with an undisclosed retailing giant under which it will provide support to the latter’s automation and robotics needs.

Drugs under Schedule II are classified with a high abuse risk but also have safe and accepted medical uses in the United States. These include certain narcotics, stimulants, and depressant drugs.
Meanwhile, Schedule I drugs, where cannabis currently falls under, are those with a high abuse risk, which means that it has no safe, accepted medical use in the United States.
Earlier this month, President Donald Trump said that his administration was looking to loosen federal restrictions on the use of cannabis and would make an official decision in the coming weeks.
