Shares of legal-cannabis company India Globalization Capital Inc. (IGCC)  soared as much as 49% Wednesday as many pot stocks rallied.

IGCC rose as high as 64 cents a share before dropping back to 59 cents shortly before the close, up some 36% on the day. The stock rallied on rumors that it's gearing up to launch a line of cannabis-infused drinks.

Other pot stock rose as well on expectations that demand for quality pot will continue to outstrip supply -- particularly in Canada following the government's recent decision to legalize recreational use. Canada, which last month legalized recreational cannabis, expects to see up to $7.17 billion in cannabis sales in 2019, according to a recent report from Deloitte.

Aphria Inc. (APHA)  rose 9.7% on the New York Stock Exchange to close at $8.49, while Aurora Cannabis Inc. (ACB)  added 8.5% to $7.91 and Canopy Growth Corp. (CGC)  gained 7.3% to $34.

However, other names in the sector fell. For example, Origin House Inc. (ORHOF)   fell 4.2% to $5.95 in over-the-counter trading, while Tilray (TLRY)  lost 2.7% to $110.88 on the Nasdaq.

"The price action in the sector is really all over the place today," said Charles Taerk of Toronto-based Faircourt Asset Management, a sub-adviser to the Ninepoint Alternative Health Fund, which invests in cannabis, nutrition and nutraceutical companies. Taerk said cannabis stocks were seeing "choppy markets" based on different news from various players, coupled with expectations of new participants entering the space.

Recent disappointing earnings results from several legal-weed companies had spurred some investors to snuff out their pot-stock holdings. However, Taerk said Wall Street's broad rally on Federal Reserve chair Jerome Powell's semi-dovish remarks lit much of the marijuana market back up, especially given that many pot stocks' valuations had recently fallen.
