RE:Good Work IrwinAnytine shares are issued they are out out with something being gained in return, it's a trade off.
Tilray is expanding it's collection of breweries in the US currently. This can be expected to have been done through cash and / or shares. In return the company gains new sales revenue, more branding as well as additional channels to market for cannabis infused drinks down the road should the company opt to go in that direction.
I order to understand the value of these trade offs for the company (dillition vs value add) you need to understand the fundamentals of a stock.
Adding sales capacity aids in future sales, assets and liabilities they take on change the companies enterprise value, price to Book and price to sales ratios.
These numbers officially update every 3 months via the QTR reports. Between reports you can estimate the change to the fundamentals based on the information you can gather regarding each deal.
Daytraders and Swingtraders avoid this work and just simply trade on chart patterns. Long term investors make the effort and consider the fundamentals, they also consider much much longer timelines.
