The amount of just basic, rank ignorance of finance and economics evident in both the article and the comments is disheartening - if not entirely expected and predictable.
Elon Musk isn't a trillionaire. He's barely even a billionaire. "On paper" means it's pixies and fairy dust. "Net worth" has become a convenient 'shock value' to wield against the successful. It inflates actual monetary worth on an imaginary scale. Fits perfectly with the Little Red Book of anticapitalist propaganda - which is wielded endlessly in the comments.
SPCX the stock is not an "ETF". If you're going to opine on investing, at least bother to look up what a TLA is before spouting off.
A company "valuation" is nothing more than a calculated prediction value based on a simplistic formula that is only meaningful if the company performs 100% in line with the vague predictions, and, BREAKING NEWS, predictions are pixies and fairy dust. There is no 'dollar value' that one can earn from or profit from in a prediction. That should be evident by the fact that the valuation was "calculated" in the trillions of dollars before a single share was sold. Lots of whiners here gleefully predicting that the stock will crash and lose everything, even shorting the stock to try to profit from it. Well, go right ahead. That's your choice and your prediction. Investing is a form of gambling, albeit if you learn how to 'count cards' you can do reasonably well at it.
Index providers "Bending the rules" is their own choice; Since the whole idea is to maximize profit/return, they aren't doing it in order to be 'cool', they're doing it because they believe there is future profit/return to be had. And lets just ignore that there are winners and losers across all indicies, it's not like the same exposure hasn't always been there, regardless of index type.
The article is laughable here: "[...] inclusion forces automatic buying, which means millions of savers could gain exposure to an unprofitable company without ever choosing the stock." News flash: "savers" are not "investors". If you're a saver and you pay attention, you have a SAVINGS account at a bank and you earn, if you've done your homework, about 3.5% interest, which keeps you up with inflation at best. Savings and Investing are two different things. What's in your 401k has always been subject to profit and loss, based on what the 401k managers choose to invest in. I worked in a union long ago that made some incredibly bad choices in their pension fund, and lost millions and millions of dollars. Blame that on the pension/401k manager, not the index.
Quoting Paul Krugman was good for a laugh. The man has multiple 'derangement syndromes', and they override what used to be sound financial advice.
meh, I've barely even cracked the ignorant claims riddling the comments. Y'all hate musk, hate capitalism, subscribe to the dogma of class warfare, and blame your own failings on someone else doing well. Hell of a way to live your life. "How can I be a victim today?"
