Im gonna offer some free advice. No need to Venmo me 1% of your total portfolio balance. Based on the info you post, if you were a client I would advise the following. You portfolio should be built on a backbone of an index ETF or two. The S&P 500, the Nasdaq 100, Pure Tech etc. As an option, you can add some individual stocks that you feel strongly about. These should be blue chip, moat possessing, strong balance sheet stocks. Walk away from meme stocks, SPACs, penny stocks etc. They are like strippers, fun to look at and play with. While you might hit a homerun with one, odds are likely they will leave you poor and unsatisfied. The Golden Age of SPACs has passed.
The blue chips you choose should work in some way with your index ETF/ETFs. Either to go overweight a particular company or two, or to add coverage with it that your ETF doesn't provide. Example if you pick the QQQ for your ETF, owning JPM to provide some exposure to financials (QQQ has no financial stocks in it). Or owning PYPL, DIS and/or NVDA because you like them and want to own a little more exposure than what you get in the ETF. Build you portfolio, set it to reinvest dividends, and look at it once or twice a year and when you add money to it. Retire down the road with a nice nest egg.
As to PSTH... Keep it until you see the merger target. If its a company you want to own long term them ride it out. If it isn't, sell on the pop and walk away. As of this writing, I would only recommend 3 - 4 SPACs to buy depending on their proximity to NAV (PSTH, XPOA, BTWN and SVFA and this one is iffy). That is it. Yes you will misss some good companies, but you will also avoid a ton of dogs with fleas.
