Hey there. The stock is under significant pressure due to the short seller report and a quarter in which it saw a bit of slowing growth. The class action lawsuits are a very common thing when short reports are issued, and the vast majority of time they are a non-event. We can see law firms who are targeting Lightspeed are also targeting stocks like Zillow and Peloton. They're best ignored.
Long term, I am a holder of Lightspeed and do not plan to sell any shares. This is a stock that has considerable volatility. If you're going to invest in the company, you have to accept the fact that this type of price movement can happen.
