My thesis: any product that my wife uses this much should be worth at least $100B. Especially when the use is in conjunction with so many high dollar value activities (shopping, travel, home renovation, etc.)

For me timing is everything. When you are freshly new to the market and want to enter you would see that everything is super overbought and some anxiety will kick in that if you enter long now, the market will somehow crash. The opportunity to start a new portfolio or to add up to your current one was in the March - April 2020 crash due to the first Covid-19 lockdown. But how many times does such unprecedented moves occur? Or "healthy corrections"? I have in mind these kind of events for fresh new positions - corrections and an unprecedented events. The lack of a real Bear markets since 2008 is replaced by fierce short-term corrections generated by unforeseen events, profit taking or like the last $SPY fall - due to the rebellion of the Retail traders.
