Same here. I'm regretting not pulling the trigger on TLSA yesterday....
If you believe in a stock and its future prospects, don't live in the 'could've should've' mentality. Many of the high flying, so called 'new innovation' stocks, are still 20-30% below their ATH (TSLA and NIO included). A quick search of Cathie Wood's top 10 holdings in ARKK fund shows TSLA, ROKU, ZM all of which are way below their recent ATH. Same goes for PTON.
Point being that todays prices are still attractive if you are in long term and have a 'buy the dip' mentality. Short term though, is anyone's guess. Trying to time the market is a foolish proposition.
